Roush Cold Air Intake Kit

A cold air intake swaps the factory air-filter box for one that pulls in cooler, denser outside air instead of hot air trapped near the engine - cooler air makes a little more power and (mostly) a better induction sound. This one uses a reusable, washable filter instead of a paper one you throw away.

why this one — No tune or PCM recalibration needed to run it (unlike some intakes), about an hour to install, and it is CARB-legal for 2018-2021 model years - a real consideration for any owner in an emissions-testing state.
