SRI or CAI

ok guys, i have an upgraded SMIC (CS SMIC) and i currently have the Injen CAI, is it best to run the SRI or the CAI (performance wise) or is the gains so minimal that it doesnt matter either way....
 
repost #100,000. I wont say search though. I think it's mostly said that cai vs. sri is like apples and oranges in a FI car. The extra bends of a cai offset the cold air. I have a SRI and I love it. An added benifit to the the SRI is not having to worry about hydrolock (not that we get many downpours in NC). I thin the CAI sounds better :)
 
which one makes you feel sexier?

I say SRI, so you can buy my brand new perrin SRI that i have for sale right now!
 
i just hate to think that i paid $xxx for a CAI and then im going to convert it to SRI....hell i may give it a shot and see what perfomrs better IF a difference is noticiable

thanks guys!
 
I for one am not converting my Injen. I would like to see a legitimate dyno on a stock MSP showing the effective gain or loss with a K&N panel filter, SRI, and CAI. The CAI was my first mod and the butt dyno felt a difference and my top speed went up. Even though I have an intercooler, I still do not want to suck in hot air with a SRI or retain that ugly looking stock box.

how could your top speed went up?
 
my car has been runnin way cooler with the CAI. its a great mod im even thinking about buying one for my house
 
I've had both, and IMHO, I think your choice depends on your situation.

A cold air intake is better for a MSP engine with limited mods, I believe. It will pull in colder air, and that one extra length of pipe isn't THAT much to make a difference in killing any gains as far as the air having to travel a greater distance to the turbo -- not that intake gains in general are anything huge. However, with the CAI's designed for the MSP, you have to consider one major thing -- water. Where you live, are you prone to a lot of rain, downpours, and flooding? If so, be prepared to leave your car stranded, as the air filter sits down LOW and might suck up water if you try to drive in massive puddles.

I now have an SRI. And I can tell you it's much more conveniently located, as changing/cleaning the filter where it's situated in the CAI setup is a huge PITA. But now, I can also pull in relatively cool air even with my SRI because I have a vented hood -- and my SRI air filter sits right by the vent. And the cold air isn't as much of an issue anymore for me, as I now have a FMIC as well.

Just my two cents. Good luck!
 
Not saying that the CAI defeated the rev limiter. Just that I could only hit 120 or so before putting on the INJEN. Afterwards, I could top out higher. The engine had 10,600 miles on it when I put the CAI on, so it wasn't a case of not being broken in.

Your gear ratio won't change no matter what u do to your engine
 
Don't feel like making yet another repost of this age-old argument, and I apologize if bumping this one up is just as bad, but -

I think we all already know the arguments for and against each type of intake - cold air + more bends for CAI and hot air + less bends for SRI - but what exactly are the differences in power? I'm not looking for any more logical discussion, but simply cold and hard facts. Does anybody have dynos of each intake? IMO that's the only way we can form a conclusion.
