I am interested in getting a CAI for my 1997 Elantra. I was looking at the AOS CAI w/AEM Bypass valve. I don't know if I will gain much hp and that is why I am posting here. If you could tell me which CAI would give me the best HP gain, that would be great.

 

Wait for the new SR Cai.Its the best and it will come on market very soon.....
Keep checking the Sharkracing e-shop or the forums of TSR

 

Righ now the RS-CAI is $40 without a filter. Its shows the best gains and is really easy. Search for a random special or RS-CAI and check out the dyno's 6hp+- gain which is the largest gain so far wink

 

5.8hp and 6.1ft lbs.
