short ram will cause no problems if the maf mount is stick diameter

Cold air has about a 70% chance of causing running problems.

Neither will make even a 1whp differnce on the stock turbo. Spend your money elsewhere. A set of Samco or Perrin intercooler hoses will make a real difference and should cost you less.

K&N drop in filter is all you need to do unless you have over 300 some WHP or a FMIC.

Dyno's dont lie. Drop in panel filters yeild 0 power over a cleanish paper stock one.

Im not discounting the statement, but thats the first time ive heard that. Are there any respectable websites that have more information or testing regarding the paper filter vs. aftermarket? Im guessing that the even though the K&N filter flows better, the paper filter is capable of providing more than enough flow to satisfy even a mild modified motor?

Thanks!

It's fairly well known. Shiv (Vishnu) did some testing a couple years ago.

Exactly. Call TurboXS, Call Vishnu, hell call pretty much ANY of the major tuners and ask.

Want some REALLY interesting feedback? Call Techtonics tuning and ask them how much power they made with a K&N vs a stock paper element that had 75% of itself blocked off with duct tape.
ZERO. They gained ZERO hp over a stock paper element that was 70% blocked off. This was on a HIGHLY tuned 2.0 16v motor.

You just dont flow enough to pull more than the stock intake can handle. The best intakes in the world, when put on a stage 4 car, will only make 5-7whp, at 20+ PSI. So now tell me you think a td04 at 13-17lbs is going to magically make more power? Exactly.

I installed the APS short ram intake and it seemed to make a difference in performance. I was stuck at 13.0 in the 1/4 mile and after the install I have not seen 13's again. I have run 12.7's, 12.9 and a best of 12.6. No idle problems at all. Nice unit and was under $200. 15 minute install in parking lot of drag-a-way.

Thank you Davenow, I appreciate the knowledge!!

Now im going to mask off 70% of my paper filter, then when it gets dirty, just block off a different section and ill get more life out of my filter!

Andy

Please dont take that seriously.

DO NOT BUY A COLD AIR INTAKE!

I have a 2003 with UP, DP, 3 Catz missing, exhaust, BOV (recenlty removed) and I had a AEM CAI (removed). Well I was getting 12-13 miles per gallon and many were saying that normal or it was my driving, the lack of cats, etc. i also had surging issues, many said that was normal too since I had a BOV.

I starting posting on this forum and quickly learned that AEM CAI have issues on WRX. I removed mine and let me tell ya.....BOY what a difference. For starters no more surging! AND AND! Im not getting 12-13 miles per gallon any longer! It appears the MAF location on the AEM cold air intake wasnt so good. I put my stocker air box back in as many suggested I do. Upon doing that, my car runs better (out of the hole), no more surges, and Im getting around 18-20 miles per gallon!

THE ONLY THING that kinda sucks but doesnt suck..... I cant hear the air intake sucking in air anymore. And my stock BOV isnt as loud (not that it ever was) with the stock air box back in.

Short Ram is the way to go if you feel you need to rid yourself of your OEM intake !!!! But I would be wise and spend the money elsewhere !!!!
Put it toward an exhaust system or something.

You did NOT gain 0.4 seconds with just an intake.

I know because ~10 whp max doesn't equal 0.4 seconds. He became a better driver, not a significantly faster car.

I can say with the vf30 setup there is no real performance gain from the short ram. My stock intake box melted a bit and has a couple pin sized holes, so I replaced it with a GP moto short ram unit and am happy. My only complaint is the noise when putting through town and the men in blue are watching--It is however, rather impressive when merging onto the highway at full tilt. I've had no issues with A/F ratios or EGTS (only NOISE) that some of the early desings or the CAIs had. The intake does gets hot, and I'm not certain there's much movement of fresh air under 45mph--Something the stock box ensures.

Stock box with a K&N and elbow silencer delete is in my opinion the best setup because it looks stock, offers some sound feedback, and isn't too over the top. I will go back to this setup once it warms up. Spend your $100 on an up-pipe or tuning. Or a better Y pipe for the intercooler.
