    I’m trying to install a cp-e intake on my 2017 st2 from a previous depo-racing intake. (Previous owner, never got to know them since the car was from an auction) Depo-racing I assume uses the factory piece seen in image 1 to house the sensor shown. (I’m gonna be honest I don’t know what sensor...

    Hi! Would love to purchase one of Velossa Tech’s ram air intakes for my ST but there’s a part on the instructions that says I have the option of cutting into some part on the car.

    Been searching forums everywhere for a while now, maybe I’m just not looking in the right places. Everybody and their godamn mother has their K&N intake that just doesn’t stick out to me.

    So I’ve recently run into an issue with my Cobb intake rubbing a hole in my AC line. Not sure if it was something I did during install but even after replacement and refitment it still rubbed. I had to end up bending the new line a bit to give clearance. Here’s a pic of the new line before...

    Hey guys, I recently bought a COBB CAI from a buddy, but it's missing the coupler for the turbo side of the aluminum tubing. Am I correct in assuming that the factory stuff down there won't connect with the intake tubing? If not, what could be my options? Does anyone sell just the couplers...

    Currently on my ST I’m running an injen CAI, AWE track edition catback exhaust, and the turbo smart BOV. I’m wondering if I get a catless downpipe will I need a tune? Bc I’m running stock tune right now and want to keep it that way.

    I've done 54k miles and have come to the conclusion that CP-E's intake is causing the P04DB CEL to display on my 17' Focus. With the car mapped or stock and the CP-E CAI installed the P04DB CEL displays randomly after 1-5k miles. Reinstalling the stock intake clears the CEL in about 30 miles...
