CAI sounds sick in my car...

that is all...

its worth it just for the sound...

 

haha and here i was expecting more.
i think when i get an intake im gonna go with either m7/ddm or alta.

 

I could really care less about sttraight line speed..but it does give it a very noticeable extra jolt..but it sounds freaking incredible..I also got an ALta 22MM RSB in...Feels so amazing in the turns!! OMG!!!!

 

I started with the Ultrik cold air and didn't really like it, I recently installed the Dinan Closed box intake, gotta say much better product
All up to you, check them out though.
It fits right into the lower half of the existing air box.

 

I cant wait to get my alta cai!

 

Wonderful sound, like the "new" Italian job movie. Some small-throttle-opening whistle though, do you get that too?

 

Thank you for the biz-nez and the post! Let me know if I can ever help in the future!

See ya!

 

I'm definitely putting in the K&N Drop-in Filter, but what about the CAI? I assume this voids the warranty. Is it worth it? How does the Alta compare with the K&N?

 

adam76, I'd pass on the K&N drop-in. I had one. It doesn't make a noticeable amount of power (it would be hard for even a dyno to tell) and K&N's just seem to let too much dirt past. I went with a Webb Sportbox and am very happy with the results. The only problems you should have with warranty is if something happens to the engine and they blame it on the intake (but they could also blame it on a panel filter). Also, don't you have a Cooper? These are all intakes for the Cooper S.
