so i want to make my first mod to my '02 p5. i'm having some trouble deciding on the injen CAI or the AEM SRI. i can't seem to find any info on the differance between the two. i understand the basics. is one better? if so, why?
thanks for any thoughts!

CAI-Filter in fender well.
SRI-Filter in engine bay.
There is a slightly increased loss of power in the lower rpm range with a CAI.
SRIs tend to be noisier.
Don't expect much power gain with either. 2-4 whp tops. But you car will rev smoother and will pull better in the higher rpms.
Oh, and save your money and buy an e-bay intake for 60$ (or less). Just make sure you buy one that fits. If you're not sure, post the link here.

My first mod (and only mod, so far) was installing a TWM Performance Short Throw Shifter Kit. And man, what a difference. Driving is so much more fun now. Best bang for your buck in my mind.

i have AT so i don't think that would work.

i've looked at the ones on ebay and the look kinda cheap. that makes me nervous. if the name brands are made better i think its worth the money.

I forget who said it on here, but I know somebody had a good point. "A metal tube is a metal tube" or something along those lines. I dont have one yet, but many people on here and elsewhere have one anf it seems to work just as good as any other.

Thats how i am too, but from what i've heard the gains are the same, I personally would buy an Injen because they are said to make the best CAI but thats just my $.02.

that would be Roddimus Prime,,, 'a bent pipe is a bent pipe', good point though.
Most of us have the ebay intakes, and we upgrade the filter to the K&N..

I personally have the ones from ebay and had it since april when i first bought the car. No problems, love the sound at 3k..

hope that helps.

i use the AEM SRI, but id recommend the Injen although im sure itd make little difference it seems itd be a tad better.....but im with the people that dont trust the ebay one...id rather have a quality built peice than a shitty peice i got for cheap

audio_nut

i have the injen and it made a big change in my take off speed...but they all work good

I bet the AEM or Injen ones make a difference....to the pocket book. Personally, I have the ebay one. I'd rather spend my $$ elsewhere.

Ain't it the truth. My SRI was a whopping 48 bucks. Someone please show me on a dyno graph that the AEM is $100 better.

I got Ebay CAI... just need to upgrade the filter.

Roddimus Prime

I have the Ebay CAI and it looks IDENTICAL to the Injen that retails for $225. I paid $48-60 for my CAI.

just fyi though...the fastest protege at our meet was Jonesboy running only the ebay cai, obx header (cheap) and obx catback (cheap). I don't think because something is cheap it's not as effecitive. My supercharger kit is almost $600-1000 cheaper than some turbo kits and I had no problem outrunning all of them.


BACK ON TOPIC....my first mod would be a AWR front motor mount....oh wait you have an automatic?? yeah, I'd still get it.

I say for a first mod it should be a set of springs! It will be a hole new car. And if your willing to spend that much money on the intake than spending 200 on springs is with in your buget. Then go the ebay route. I also have the ebay intake and it rocks 60.00 to the door.
