Air filters

[jdm213]

Well im cleaning up my engine bay, but i want to take out that ugly airbox. So I just wanted to know if i can put a new air filter but keep the stock intake?:hsdance:

[let5l1de]

I assume it is possible but ca smog requirements may restrict you from modifying the intake. Besides the smog issue, an maf adapter for air filter, and inlet air temp sensor adapter is what you would need. Most people just let the inlet air temp sensor hang loose since there are not many adapters available for this.

its possible but like mario said its against ca smog requirements
plus it burns ups MAFs which leads to idling issues.

just save up for a used carb legal intake. you can get one on here for around 75 bucks. just be patient for a good deal, its always better to buy legit parts the first time instead of wasting money on crap. :2c:

well yeah cuz i was thinking of buying a mushroom head filter and just put it on my stock intake.:mepoke:

like i said before.. you can do it.. but you will regret it later.
it WILL burn up your MAF.
you will have to keep giving your car gas to make it idle. if you dont it will just stall. my friend did that on his intake and burnt up like 4 mafs before he got the picture

K&N makes a nice intake setup that is not too expensive, but most importantly it is CARB approved and comes with the sticker with the CARB number on it to keep the smogman happy. Then you can lose the airbox...

Why would changing your intake filter lead to your MAF fucking up?!?! Who's feeding you that BS???

have you ever put a cone filter on a stock intake tube like the OP was talking about doing???

go put one on and drive around for a day then tell me how well your car idles

K&N makes a great application that bolts in place of the stock air box like you want and has a CARB EO.

The only problem with a wet type filter is, you can over saturate the element. With the light weight K&N oil, guess where the additional oil is sucked into and what sensor it may contaminate?

Regardless, IMO K&N is a great filter manufacture.

As an at heart musclehead, I'd say just replace the stock air filter with a better one. I've seen alot of 500+hp v8's with the stock airbox... Which is good for you because of CA's emissions laws.

Then again, 4cyls are a tad different. You can try modifying your stock intake box a little to help breath better. remove the baffles and what not, get a better filter. Its cold enough over on that side it won't make a huge difference if you take off them there fresh air tubes.

And K&N manufactures the air filter for the M1 Abrams tank... just a little FYI

To bad it has never contaminated a MAF sensor to failure even with over oiling. The oil will not blow off.

I have put K&N drop in filters in every vehicle I have owned. Never had a complaint.

lol @ failure. Someone else must have posted failure.... And since when have we taken one test from any manufacture as the answer for every application or situation?

Ok here is my experience. I was employed with SuperShops for 6 years and also worked with CarCustom for over 4 years, not to mention my personal experience of 18 years. As you may already know, SuperShops was one of the top 10 retailers of K&N filters. With the volume of sales, we saw everything come in to us regarding feed back on many parts sold throughout the chain of over 170 stores nation wide.

Anyway, I was serious v8 gear head. My love at that time was small block Chevy 1st gen and SB2 engines. I also used the E-3750 (14"x4" round) element in a drop-base bottom with the chrome K&N logo top. This is where I encountered my first oil collection found on the inner lower lip of the filter assembly. I contributed the collection due to ambient under the hood temps and possible over-saturation.

AirCooled Volkswagen (yes i know...) was another fun time for me in the performance industry (may the "vw and performance is an oxymoron" comments begin). Long story short, over-saturated K&N filters sitting on flat based, almost non recessed bottoms on top of Weber or Dellorto downdraft carbs (especially with outerwears) showed the signs seepage onto the venturis. This wasn't a big deal since VW's are notoriously known for carb rebuilds and oil leaks among others...

Who is to say this could not happen with a saturated tapered or oval style filter?

IMO, K&N filters were and still are one of the best filter mfg's (as stated earlier) in the performance industry. I personally have sold many hundreds, maybe over a thousand of the K&N filters, installed hundreds K&N products and customers serviced probably over a thousand times. The large majority of my installations as well as customer installs have worked in near flawless performance.

As with any manufacture, we do come across situations we would have never guessed could have happened. Once the product has reached a customers hand, anything is possible...

ANYTHING!

-sell your 240sx
-eat a gun

i dont need it to be carb legal its just a brand name filter i just dont like the brand. i prefer to get an ebay filter and it will work the same as that and for less money. cmon some of you have sr, or rb its already not legal !:fawkd:

If you ever have a maf failure you can mail it to them and they will test it for you and show you how it failed.

I don't see how your anecdotal evidence proves anything.

Do me a favor. When you get your hood poped and a ticket for a non-carb intake. Don't come here whining about it.

Ebay filters are usually cheap paper shit that looks like a K&N. It won't work the same and will clog up after 15k. K&N will be good till 50k.
Foam filters break down over time and shit goes into you intake. I have had people with green foam in their maf.

You have a KA which is legal so why not keep it legal?

lol! I never said failure. Not my fight.

I may be a victim of my own cognitive bias at times. However, we are all entitled to our subjective validation. Hence, my personal experience as stated above.

We should request K&N to release or conduct more real time R&D studies of each individual filter types for increased consumer/public knowledge.

you don't like K&N but you like "ebay brand paper cone"? you're a fucking dipshit.
i just wanty to clean up my shit
what does this mean, clean up your shit? is the stock airbox in some way dirty?
based on the nonsense you post, i'm sure the engine bay is caked in grime, has exposed wires, etc, and you probably have a smashed in quarter or something severe that needs attention more than replacing a functional filter with some noname shit off ebay.
you're a moron, kid.

well its like if you have an sr and then you want to put a legal intake and shit , so thats retarded its already illegal, thats my point... idgaf thats why my shit it not legal, my car is all motor with engine rebuild, i have megan racing testpipe and headers, .. i know it aint fast but it sound nice, but i could still get pulled over, so whats a legal intake gonna do, make it legal? .. not a damn thing, so i want something not legal i dont want k&n :duh::Owned:

I'm sorry, I should have been more clear, being that your reading comprehension is at a second grade level. What I meant to say was: You're an idiot, and since people like you are the future of this country, we're all doomed.

Clear now? Good.

Dont tell people to stfu. You will get a zilvian bukake if you fuck around. Your making a stupid mistake here. If your keeping the origional intake pipe, your just losing throttle response and power.

Keep the airbox, or donate it to me. I can not stress that enough.

BUMP OLD THREAD...Damn and i was considering putting on a cone filter with my stock pipe, oh well. Anyone else have any good/bad experience with this setup? Just curious.

BUMP OLD THREAD...Damn and i was considering putting on a cone filter with my stock pipe, oh well. Anyone else have any good/bad experience with this setup? Just curious.

My guess is that it would probably be the same as a cone filter with an intake pipe. Not much difference from stock airbox in my opinion, besides looking a little better in the engine bay. My 240, and along with many others are so loud, that I can't even hear the intake noise.

[Brian04]

I just put a K&N Cone Filter on my stock KA intake tube a few days ago. Not much i can feel in terms of throttle response or what not. What i can say, is that it makes my S13 sound like a grunting fart can. Especially with an HKS Hi Power. I'm hoping it's just the intake baffling.

Anyways, point is i need an aftermarket intake tube to accommodate some extra loose hoses, and to increase airflow. No complaints on my MAF.

[kuelee]

well i ran a no name brand cold air intake. everything was correct, but my car idle's weird.. not normal.. so then i switched it to short ram.. still fucked up idles.. now back to stock and i think my maf is fucked.. when i come to a stop, rpm drops to like 4-5 hundred rpm// never did that before..until the fucken intake.. keep it stock..

You seem like a real smart guy. Thank you, sir, for that wonderfully insightful post. I'm gonna take my short ram off first thing in the morning!

[stinky_180]

I run an Injen short ram on my KA24E with the the IAT sensor disconnected. Perfectly idles at 750... I've seen stillen sell air filters that include a IAT mount on the filter element itself. I believe it is discontinued....

[SlideWell]

honnnnnduuuuhhhh

[hOngsterr]

cone filters on stock piping. do it.

i never had a idling issue regarding my filter.

My 91 DOHC idled rough and experienced acceleration issues. I had to put my stock airbox back on.

[Bigsyke]

Let see the benifits of keeping the stock airbox. Cooler air, better oil cooling with the PCV system, less chance of detonation, less heatsoak, better throttle response, and its tuned to the IM runners. Didnt most ITR owners come to the conclusion the stock airbox unmodified was the way to go? Our airbox is a lot less restrictive.

Maybe just get an AFE panel filter. Ive gone back and forth about 40 times this summer with a MAF adaptor and AEM dryflow, vs my stock airbox and different ducting. It seems the Airbox's restriction is the filter element. But it resists heat soak. The AEM dry flow breaths better, the Exhaust tone is alot quieter but after 40 minutes of driving I can hardly make it up a hill.

With the OE airbox I can make shrouds and ducts to seal off the areas around the radiator, while still getting fresh air where I need it. I can also Remove the Left rectangular resonator port, and replace it with 2x 2" ABS 45* angle pipes from home depot, and it pulls in more air from in front of the bumper. With cooler air I can run more timing.
