Description of Roush Performance Products 421827 Intake

No need for calibration or a custom tune, as this CAI system was engineered, tested, and designed to work with the completely stock 2.3L I4 engine. Replaces the restrictive stock air intake, unlocking latent power and fuel efficiency. 2015-2017 2.3L I4 Eco boost engine brings staggering performance increases that can be achieved with an installation that takes under an hour with no calibration required.

Easy installation, nice wins!

Installed about 1000 miles ago and love it. The Mustang is slightly more responsive to the throttle and will definitely throw you back in the seats a little harder. If you want a quick win that doesn't void your warranty, this mod is for you!

Pros
  • Acceptable
Cons
  • Expensive insurance

Good product! First I tried the K&N dispenser

Great product! I tried the K&N inlet first, I had problems with the check engine light coming on. Returned, bought later. Very easy to install and love the improved performance! I recommend this product without hesitation!

Pros
  • Impressive
Cons
  • boring packaging

Very disappointing Best in Filter

Interesting, all these great reviews are just made up, just installed in 2017 Mustang Eco, very slight sound improvement, first CAI system I bought that runs quietly, no noticeable increase in performance, was just too install but cost $400. I am extremely disappointed. I think that's why Roush Racing isn't doing very well in NASCAR at the moment!

Pros
  • Best
Cons
  • Ugly packaging

Worth the investment!

Installation took less than an hour, requires socket set, flat head screwdriver and pliers. I saw the CJ Pony Parts video on YouTube and this Cai sounds fantastic. I definitely noticed an increase in HP, I highly recommend Rousch. Yates performance delivered on time as promised by a great seller.

Pros
  • New

Very disappointed with parts

I am extremely disappointed. I think that's why Roush Racing isn't doing very well in NASCAR at the moment!

Pros
  • Finally bought
Cons
