Air Intake Question.....

[Silvia240sxxx]

I was looking on ebay for a cheap intake cuz I never really thought of them to really help much, but knew they help somewhat. And seems like a waste of money to spend $200 for... :tweak: So anywayz i was reading one they were selling that had a heat shield over it. If you read the description they explain that with the heat shield the air that goes in is 86 degrees cooler.... :wtf: That's hard to beleive that little piece of metal cools it down that much. Anyone have any experiece with that kind of intake??? Here's the link of the intake I was looking at.

That maybe true in the case of an engine fire, but other then that, dont use the heat sheild unless its protecting the intake from water like a sw20.

just get something with a K&N filter.

just get something with a K&N filter.

K&N's are not so great for 240s, over time the oil will taint your MAFS.
Dry filters = less time cleaning & less potential for funky idle.

edit:
I just noticed the guy double posted, so here's my reply from the other thread (which should be deleted... hint-hint, original poster):

HAHAHA omg.

TYTE Weapon-R intake y0! haha...
IF they did get and 82deg drop, i'm more than sure it has more to do with their little CAI-ish feeder tube that's right next to the intake (look to the right, near the headlight, see the tube from what I assume is the stock airbox (I forget what it looks like, I've been w/o one for years)

So their claiming their "K&N like" intake does better when you cover up 80% of it with a "heat shield" huh? A shield made out of a "composite plastic" that's just painted with crappy chrome paint (yay krylon!). Oh... and it has the built-in Vortex/Tornado unit that's been debunked by pretty much every mag and TV-show that's reviewed them.... PLUS you get a nifty lil resistory to further confuse your poor ecu.

What a bargain!

To put things in perspective, anything will be a step up from the restrictive stock airbox, but how tall of a step is the variance. For $69+29 S&H (BULLSHIT S&H charge), I'd say this intake has precisely dick to offer you. For $100 I'll keep my Apex Power Intake over this POS any day... I'm sure my intake would show a 80 deg drop in temp too if I had cool ambient air forced at it's opening What a silly auction. Oh well, at least they don't claim to get 30hp and add 20mpg to your fuel efficiency.

[Advan]

I was so thinking about spending the $118 for the Apex intake, but I went the drop in K&N route for the time being, till I've gained enough money to not only put towards my RB street exhaust(headers-presilencer-duals exhaust) for $987, but also have money left over for me to buy the Apexi intake and almost enough for a pair a rims...or maybe a paint job.

Edit: but in the end, I have no clue how ya can trust what people say on eBay. For some reason, I feel uneasy about bidding on things there.

maf adapter and a cone filter 20 bucks ebay......... i use to have an intake.. converted back to stock ... one of the best things i ever did...

[pignosecoupe]

I have a K&N cone filter (and adapter plate) on my KA. I didn't notice a HUGE difference (I am just being honest). Sure I would like to boast about a huge HP increase or somthing like that. The main bennifit I have noticed from my setup, is the sound. I have the stock exhaust, and it produces alot more engine noise (which sounds AWESOME). And hey, I never have to replace the filter. !!

[infinitexsound]

yeah stay stock if you arent gonna do any serious engine changes... theres no point at all ... my opinion

[darren240]

i got a injen cai, and i am very satisfied even though it cost a shit load. :D

[Project D]

Im just buying the apexi power intake. Seems like its the best option for what I am doing..

[AllenRPS13]

i sed to have an intake, but i don't really like it, it makes my fuel economy go worse, don't know why...
now i change back to stock pipe with apexi filter, it works great on my KA

[infinitexsound]

ding ding ding* smart guy............. what a waste of bloody money buying a full intake... u can just make one ... money can be better spent elsewhere..

[Silvia240sxxx]

Hmm i'm glad people agree with me that the intake on ebay is a full of horse shit.

[SilviaDriver]

^^^ if you knew it was horse shit in teh first place why even post? obviously your first intial post you were somewhat confused about the truth. no need to cover things up now

[junkilo]

thanks for that info, I didnt know that, and suspected funkyness with the K&N and chucked it in the trash a while back and now I'm glad I did and went back to paper.

On the subject of shiny intakes........ all roads lead to ITBs and turbo so don't waste your money on chrome. Move the battery into the trunk, or move it somewhere, cut out the tray, punch a hole through so you can see to the ground, get some 2" abs, proper rubber adapters and fittings and you can turn you stock airbox upside down with maf connected and plumb from there into the TB. Cheapest fun mod evar.

your right..i was confused...but that is what my initial thought was that it was a piece of shit...but I wanted to see if anyone owned something like that and it actually worked well....well that's what i was hoping.

[Ghettokracker71]

CAI-ish feeder tube? Dear god I hope your not talking about the stock resonator tube that leads to absolute nothing-ness....


Although I cut out the buttom of mine and ran a large tube into the stock resonator so it blows a lil on the filter :p




On more topic specific note: Cheap intakes definitely make a difference. I have an eBay intake on my 240sx,and it definitely was noticeable,but barely. You are only gonna get so much out of an intake. What does it matter what brand it is? Its just a fucking pipe,a pipe. Thats all. If it comes with a shitty filter like mine did,just pick up a decent cone one. Don't use any oil on your filter, I personally have fried a MAF or two by doing that.

[m0rex]

Me and my friend always have a discussion about the adapter and filter on my stock pipe that goes to the airbox is not a "cold air intake". Does the tubing matter? Plastic or stainless steel? Sorry for the thread jacking but since we are on topic.

You probably over-oiled it. I've been using a K&N for years and it's never given me trouble.

The best part is how they explain its' usage and benefit. "You will not gain 20 horsepower. Realistic power gains range from 7 to 10 horsepower at the engine." Think about their demographic when making that comment...

[Silvia240sxxx]

I think that guy is an asshole. If you read my post....I obviously dont' think this intake is going to work. Of course I had some doubt..but why not ask people to see if they had one...just to confirm how bad it was. You can always think something is horseshit before knowing for sure if it would work or not.....asshole

[ranisron]

I have K&N Cone filter in my altima with stock pipings and Maf adaptor...
K&N drop in for my 240sx...

I can always switch around between the two (the good thing having 2 Ka24de). but I doubt I would do that...

[Pank]

holy shit, that thing looks like the BIGGEST BOV I have ever seen

whoa, am I the only one who noticed they put a color cast on the pic so u cant just get radioshack resistor and sell them as the same thing? With the color cast on, NONE of the stripes are in the resistor color code....

Ahhh yes, the resistor color code... that Violet... what a slut.

[90rps13]

You're never gonna get 12 ponies out of that thing on a KA unless if you have many other mods like full exhaust + headers, etc. Looks like a nice piece, but those things usually never fit right, or you get the wrong adapter, or whatever. It would be more just for bling. Just be happy if you get 5 hp out of it or if you could even feel the difference. Just my 2 pesos. Peace!

I thought about running mine like that on my DOHC, but I thought the ECU and MAF needed the intake tube to be a certain length. how does yours run?

really good. the maf/ecu didn't complain much. Biggest improvement is wot over 4k rpms, it helps a chunk at maintaining precious vacuum to suck up more air than the stock feeder. Sound is just right with using the stock airbox and a paper filter (undetectable until you mash it around 4k).

The battery plate has been sawed out and theres a 4inch feeder tube going straight down.

[TheSquidd]

How much oil did you use on the K&N to get it to taint your MAF????

Let's just say, I am THOUROUGHLY involved in the performance air intake market, and unless you completely caked the filter in oil, a K&N will not mess up your MAF.

Paper filters flow literally a small fraction of the air compared to K&N's cotton filter element.

Foam filters break apart and get sucked into your engine as they degrade.

Rip off cotton filters (fleabay etc.) are usually only 2-ply elements with knock off oil doused into them. The oil blocks more air, filters less dirt (you'd hate to see what these filters allow through the element.) and fall apart at the seams from poor build quality.

Heatshields are ineffective. Period. What matters to a combustion engine is Air DENSITY not temprature. On a cold day, the air is DENSER than a hot day. But the heat from your engine bay is not decreasing the density of the air around it, the air you suck in on a cold day with a hot engine will be the same density if you have a heatshield or not.

Uh, the end. Buy a tube, put a K&N cone on the end of it and you've got increased horsepower (While not large gains, it's more than you're getting with your paper filter. Even drop in replacement filters have dyno'd at around 8hp to the rear wheels on some applications.)

[Irukandji]

errr dont waste your money. i have an injen intake + K&N cone filter and it seriously didnt make that big of a difference. Throttle response was better and the engine was a bit louder.. but other than that.. i regret spending the $. save your money for a K&n drop.

What's the part number for the power intake? I couldn't find any for S13's but the power intake for the US spec 95-98 240sx would fit a 92 240sx correct? Same engines..

[420sx]

2 clamps, 2 rubber couplings from home depo, a pipe with some cutting, and a filter. k&n is just fine. bam bitch. done. whats the fucking problem? why post this useless shit over and over? stop beating a dead horse. its an intake.




its just a fucking pipe with a filter. goddamn it, when you people will learn. it simply purifies air going into the engine. you are still stock. you are still n/a who gives a flying horses ass.

[aznpoopy]

this is true

the reason people taint their maf is because they use a shitload of oil when they recharge their filter

just spray it on so it covers it. you dont need to put on a lot.

i've had a k&n filter on my car for 3 years. it actually came with the car so it's probably been on a lot longer. maf is still working fine.

[junkilo]

bumping a thread, need to zonk squid here.

well ok then.
Paper filters flow literally a small fraction of the air compared to K&N's cotton filter element.
misleading but true.
Heatshields are ineffective. Period. What matters to a combustion engine is Air DENSITY not temprature.
hello!? How do you get a increase in air density on n/a cars? for us simpletons that means air temperature.
On a cold day, the air is DENSER than a hot day. But the heat from your engine bay is not decreasing the density of the air around it, the air you suck in on a cold day with a hot engine will be the same density if you have a heatshield or not.
you just said air density is proportionally related to temp (which it is). good. hint:: on a hot day where does the coolest air reside?
Uh, the end. Buy a tube, put a K&N cone on the end of it and you've got increased horsepower (While not large gains, it's more than you're getting with your paper filter. Even drop in replacement filters have dyno'd at around 8hp to the rear wheels on some applications.)
again stop posting your misconceptions about air intake. air breathed into the engine gets sucked because the engine was making vacuum to suck it in. You aren't going to be magically making it over 0 bar with with a k&n filter. If you remove your filter all you get is increased throttle response as the air doesn't have to travel very far to get to the runners. The reason why you occasionally see dynos that make hp with changing filters is because in some applications the oem designed paper filter didn't have enough surface area to flow for their non-oem application. Most dynos showing these are people with big block v8s and turbo applications where they need 500+ cfm and are getting restricted by missized paper filter. The number of oem incorrectly sized paper filter elements is probably very low.

I feel like posting a tech thread on intake theory now.

[420sx]

I thought about running mine like that on my DOHC, but I thought the ECU and MAF needed the intake tube to be a certain length. how does yours run?

lol.... what???? you know what a MAF does? if you do then it makes no difference. anyway the shorter the better. less restrictions

[kandyflip445]

I have a ebay intake with one of those stillen velocity stacks at the MAF opening instead of the one that came with it. It has a K&N on it too. Yaaaay. It actually doesn't make it any louder. WTF? It is the same volume but you can hear air sucking now. Weird.

[Enemy]

I got a MAF adapter and a cone filter to replace my stock airbox but it made the idle funky. Maybe cuz that one hose that goes into the stock airbox from the exhaust isnt doing what its supposed to. I just put the stock shit back on.

I did also remove the fender lining and chuck the intake resonator thing as well as the flex tube that connects to the bottom of the airbox.

Any ideas why idle got funky??
