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. I attached the picture for reference but was wondering if that’s something that is optional. Do I have to cut into...

I got a used depo intake not realizing the fitting for the breather hose was missing, anyone know what size the fitting is?

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. I’ve personally never seen Individual throttle bodies with the open intake on an ecoboost and I’m curious if...

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...

Hey guys , currently purchased the intake tube from fswerks. I currently have a cattless downpipe, custom exhaust, And BOV, will I notice a difference in noise or possibly even a drive difference ? Thanks

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...

Plan on buying a Roush Intake for my FoST. I live in CA so I need one that is CARB approved. Please watch this video from youtube (not mine) and forward it to 0:20 It flutters. I want to know if that is safe or normal when you install n CAI on FoST. Need a little help with why it flutters...

I just purchased a 2015 ST2 with 49k miles, and I’ve read a lot about the carbon buildup on the intake valves. I was just wondering if anyone knows of a place to get them walnut blasted? Will a ford dealer do it?

So I have a muffler delete on my 14 focus st and it sounds ok. Very quiet still which sucks. Not sure if deleting the res will be too much or if I can install a more performance resinator that will make it louder but not horrible. Also I need opinions on an intake lol. I’m trying to find one...
