I have an 08 GTS 5spd and am looking to upgrade the intake. I currently have a takeda SRI, but it rattles when I start accelerating from a stop. I really like the K & N series, as I really dig the red piping. Does anyone know if the K & N CAI is compatible with the 4b11 N/A motor? I have tried to look it up, and I can't seem to find anything either way.

 

i know the takeda sri had some fitment issues but i thought they had fixed they?

either way, if its installed properly it shouldn't rattle at all.

i would try to sell that takeda and get a K&N SRI

but if you're set on a CAI my friend has an injen for his 4b12 and it sounds amazing and he said the gains are fairly noticeable too. i think you should look at injen and AEM, i've heard good things about AEM too and for sure they have em for 4b11

 

I really like the K & N because of the red tubing (red being my favorite color and all). I was hoping that I could use it, however I am doubtful. I am probably going to end up getting an injen, as I hear they are louder and produce more power then the aem system.

 

injen is a great choice, only hear good things about it and if you're set on a CAI then that's the one i would personally pick.

have a look at the K&N SRI though, i have it myself and absolutely love it. The sound is awesome and you get some noticeable gains in the lower band RPMs. Not to mention K&N is a really well known and reliable brand for intakes so you know it won't throw any CEL codes or give you any issues. comes with a heatshield too and you don't have to worry about hydro locking your engine

 

I am more or less sold on the CAI. I'm at a toss up between the AEM and the Injen. The Injen uses an oiled filter system and sounds like it might require more maintenance more often. I also read that the AEM sits higher off the ground leading to less chance of water damage. Anyone have any input?

 

I have the k&n SRI, I like it. It has almost noticeable power gains, lol. And very easy and quick to install. It is quite loud tho, just be prepared for that.

 

I have a injen sri their is a noticeable gain and it sounds a lot better but pretty much anyone you go with should be similar.

 

i wanna put a SRI on my 08 Gts, and i was thinking for Injen mainly bc i want the Injen exhaust aswell. does injen sell a AM heat sheild?
