Sounds amazing

Removing the factory intake proved to be the most time consuming yet install is simple. Sounds amazing on start up and Acceleration. Great product and great price. Very happy

Wow! Uncorked

Install was easy as hell, Paired with the race exhaust, header, Brisk spark plugs, and 93 octane tune this realllly opened it up. Above 4000 rpm it almost feels as if you’re giving it a little shot of nos. Don’t get a tone of induction noise from it or at least that I can hear but it really woke up the car. Well worth the 200$ would highly recommend buying it if you want to feel a bit more power.

Choke point in middle of tube

This product is absolutely garbage if you want performance. The tube has a choke point at the mounting bracket that reduces the ID to less than 1.88". That's smaller in diameter than the stock throttle body. To make flow even worse it has the MAF sensor tongue in the middle of the choke point. This product will starve your engine for air and make any other intake improvements obsolete.


Hi Phillip, We are disappointed to hear your comments on our Cool-Flo intake. First of all the middle section of the intake is intentionally reduced to 2.5" tubing so the car doesn't give out CEL codes. Unfortunately the Mass air flow sensor on these cars don't run properly if the tubing is all 3". Also the actual ID in the middle section is 2.40" NOT 1.88" Lastly the MAF sensor fitting on the tubing is in the same location and depth as stock unit allowing it to work properly with the engine pcm. This does not starve the engine in any way. If you have any questions please contact us at 714-693-2555. Thank you
