I'm in a good mood, despite being sick.
They're pretty much identical, pick one.

Apex has he best flow and filtration.

[bardabe]

^^^ what he said

[johngriff]

I demand flow bench's or you edit that statement.

I demand flow bench's out of ALL intake systems right now.

I demand that you use a better filter in your air box, because it is a more functional cold air intake, than an under the hood filter ever will be.

Ask and you shall receive: http://www.mkiv.com/techarticles/filters_test/2/

[burnsauto]

well....with the filter still in the engine bay, it doesnt do crap, just sucks in more hot air....but, i think it was injen that makes the adapters to make it an actual cold air intake. (but you could just make your piping and stick an a'pexi filter on it for a fraction of the cost..)

[johngriff]

Wow, by that test it looks like APEX filter is the best i could ever buy.

(throws away hks filter)

Everything Japan Makes is Superior!

[usdm180sx]

Except hks filters haha

[johngriff]

Obviously they were made in america or something.

Just pick up a ebay one A bunch of people run them. After all its just a pipe and a few couplers. Then pick up a K&N Cone filter.

[usdm180sx]

Why would he wanna pick up a k&n when it was just demonstrated that apex is the best?

[LimitedEdition]

Correct me if I am wrong but thats the flow on a MKIV Supra, shouldnt it be different on a different engine? Plus, I have never had any problems with the K&N's nor has my cousin who drags 1xxxhp Foxbodys.

A filter is a filter is a filter. It filtrates air regardless of what motor it's on. If they used a 3 cylinder Geo Metro the filtration/flow results still would have been the same.

Dude that is so wrong...so you are saying if you put a apexi intake on a geo metro, it will gain the 14 hp that the supra gained? Thats wrong... Maybe I read your post wrong.

The proper way is to bolt up the whole intake track and benchflow it with each filter. This will tell you which filter flows the most cfm. The least restriction will give you the most gain.

Also it didnt say how they tested the experiment. If they just put the car on the dyno and swapped the intakes, thats not very accurate. Each dyno run could have some kind of error, whether it be engine temperature, airflow, etc. Im not saying that the apexi isnt the best but I just felt the information isnt complete.

DIY is better.

You read my post wrong. Of course it would be different for different motors. Nowhere in my post did I post that whp gains would be the same. The point is that the apex filter has the best filtration and flow no matter what motor it's on.

As far as a perfect test it will never happen. Just like we don't live in a perfect world. I have neither the time nor energy to go through the hassle. Feel free to do so if you like. I'll just go with the Apexfilter and not try and reinvent the wheel :D

[Diabolical]

Honestly, save your money.

[projectRDM]

The filter isn't the restriction, it's the pipe itself. A smooth, even size pipe without humps, indentations, or other obstructions provides a better airflow than just placing a big filter on the car. Plus as mentioned the open filter is sucking in nothing but hot air, so any gain in airflow is negated by the higher temps.

fujita f5 i hear are really nice but ive got the apex

[s13pignose]

I actually have the apexi panel filter. It's fine cept for the rubber surround on the top started to break off in chunks so I just cut it all off. Also I don't have the resonator box.
The panel filter supposedly uses the same filter element as apexi's cone filters. So therefore doesn't require oiling.

But yeah for time being until you make a choice, just take the intake resonator box off. Turn your wheel all the way to the right I think, and pull the splash guard back right after the bumper on the driver side. Thats how I got to mine

Air filter which is better: Apexi, HKS, BLitz, K&N Sports racing, (http://www.zilvia.net/f/showthread.php?t=151037&)

homemade pvc intake is best less heat is trapped by the intake plus it costs like 15 bux

You....are a fucking moron. PVC is plastic, a plastic that emits highly toxic fumes when heated. If you're running this in your engine bay, you run this risk of inhaling these fumes through your vents as the pipes melt/warp from the extreme heat under the hood. And yes the engine bay does get that hot, especially under boost.

[S14DB]

If you don't live in a carb state:
1) Buy ebay CAI
2) Throw away filter
3) Buy K&N at store(or JDM tizzite of your choice)

If you are in a CARB state, Bend over and buy the cheapest CARB cert CAI.

This is my intake. Much better than any I've ever bought. As soon as my intake piping comes in the tb peice will be gone and flex pipe. So it will be smooth the whole way.

[projectRDM]

Had one like that over ten years ago, it is the best solution for avoiding underhood heat.

[twofortyrida1388]

The usual intakes you buy I didn't notice anything but more intake noise. When I put this thing on it was like holy crap. 2nd grabs better in the bottom end and all gears pull better.

[Dream240]

Yeah but don't you lose some top end with that thing? Seems like you would have more air turbulence at higher rpms, than the standard over the shroud design.

[240on430]

I have the injen with the cold air extension that replaces the resonator.living in california, I needed a carb legal intake.I take the extension out when its raining...takes about 5 minutes.

[twofortyrida1388]

Top seems better. Like 4th pulls very well to 110-115. It should be even better when I eliminate tb peice and flexpipe. One reason may be too is that air is being forced in intake at higher speeds.
