Roush Performance Products 421827 Cold Air Intake Kit, 1 Pack, Black

Took under an hour to complete the install, need socket set, flat head screw driver and pliers. Watched a video by cj pony parts on YouTube and this cai sounds amazing. I've definitely noticed hp gain, highly recommend rousch. Yates performance delivered on time as promised great seller.

Excellent product! I tried the K&N intake first, had issues with the check engine light coming on. I returned it , purchasing this a bit later. Very easy install and love the improved performance! Would recommend this product without hesitation!

Easy installation and makes engine sound much better

Easy to install. The reason for only four stars - the sound wasn't as deep as I would have thought when into the throttle.

Wondering if all these great reviews are just made up, just installed in a 2017 Mustang Eco, very minor increase in sound, first CAI system i've purchased that is quiet, no noticeable power increase, was an easy install but at $400. Im very disappointed. I guess thats why Roush Racing isnt doing well in NASCAR now !!

Great product ,price and fast shipping

Installed it about 1,000 miles ago and I absolutely love it. The Mustang feels a bit more responsive on throttle and definitely throws you back into the seats a little harder now.If you want some quick gains that won't void your warranty, this is the mod for you!

Aye I know it's a bit pricey but DEFINITELY worth it. You hear and feel the Roush
