CAI or SRI
- Thread starter ProGenIII
- Start date
Based on the convertable K&N Typhoon CAI I have, SRI may have the advantage, based on my experience with it on everyday driving.
CAI: You actually lose some low end power from stock(seems same thing happen to other brand name CAIs as well from what I heard from people here) around the 3000rpm range, actually making the car feels slower from a stand still. But you feel more power from 4500+rpm. Gas mileage bumped from averaging 25/26mpg stock to 29mpg.
SRI: Much nicer low end power around 3000rpm that I can really feel the difference after I swap from CAI to SRI. More usable from daily driving. Not too sure about the gas mileage as I just did the swap very recently. But doesn't look like it makes a big difference from the 3/4 gas tank that my new SRI set-up has consumed. But can't really tell until I have driven the car for a while to average out the gas mileage numbers after a few refueling.
So bottom line:
CAI - better high end power at high rpm, looks cooler without the filter sticking out in the engine bay, quieter than SRI, good gas mileage, but risky of hydrolock if your area is flooded.
SRI - better low end power(more usable), loud, ?? gas mileage(but still better than stock anyhow). Slightly cheaper.
Take your pick.
Or get a K&N Typhoon so that you can go back & forth. 
I personally lean more towards SRI, just because I can feel more of a difference in the low end.

SRI is better, waaaaay better and Im getting ready to get SRI and get rid of my CAI. Well, 1st time I ever ran at the track, I had ONLY ebay SRI and I ran 1/4 mile in 16.3 seconds. Now I have Injen CAI, Jspec intake camshaft, racing beat axle back from MP3, underdrive pulley, Short shifter with bushings and BRAND NEW TIRES. I feel god damn power, but for some reason I run like crap. Last night I ran 3 times at the track and best I could do was 16.4 and worst 16.7. I think Its the intake problem. Definetly gotta get an SRI for cheap somewhere and test it out on the track again. Dont get me wrong but with all these mods I should be in 16 flat or 15.9
NO, they don't.....for they are nearly completely surrounded and are definately protected from nasty stuff from under the wheelwell.ProGenIII said:
and for NORMAL N/A cars, which are not all out raced or heavily modified...I think you would be hard pressed to measure much of a difference that you could even notice with either. So its really most likely a personal preferance.
the biggest and major difference is that its MUCH easier to change/clean the filter on the SRI.....not to mention its a lot easier to notice when its needed.

CAI on N/A cars. Have had both. I think Injen CAI performs outstanding.
An intercooler doesn't make the intake charge anything resembling cold. They just make it, 'not as hot.'MrE007 said:
A SRI isn't called a 'hot-air intake.' Any of you guys with CAIs, go for a nice long drive, then stop and put your hand on your intake. Now, see how long you can hold your hand there....
What were the atmospheric conditions during the separate runs? If you ran in february, and then during the summer, of course you will be slower. The weather has alot to do with times.DiS said:
And as for the CAI vs. SRI. Jesus, do a friggin search! There are like 20 other polls/posts asking the same question.
