Improves Horsepower. This SR Performance Cold Air Intake kit completely replaces the stock air box and restrictive paper filter element in your 1999-2004 3.8L & 3.9L V6 Pony with a high flow filter assembly for a noticeable increase in horsepower and throttle response while filtering out destructive power robbing dust particles. This CAI pulls cooler denser air from inside the inner fender well to make more power that you can feel. Reusable Filter. This kit includes a high flow reusable air filter, so theres no need to go out and buy a new filter every few thousand miles. Just clean the filter, re-oil it, save money, and go! Polished Finish. A SR Performance Cold Air Intake not only improves horsepower and acceleration, but it also improves your Ponys under-hood appearance with a striking polished aluminum finish. Now you can have the best of both worlds, performance and style. Simple Install. SR Performance Cold Air Intake kits are relatively easy to install with basic hand tools. No extra modifications are required for the installation.
