No big surprise here -- an intake will improve horsepower, torque, and gas mileage by simply allowing more air into the combustion chambers. What might be a surprise to the average SUV owner is the ease of installation of this performance-adder. When choosing an intake for your application, consider the following: type of materials used, location, warranty, and CARB approval. For one lucky Suburban owner, we tried out CGS Motorsports' new intake for the 5.3L to see if it truly was as easy as it looks. Less than 30 minutes later, we had a better-looking engine compartment, a better acceleration sound, and a better feel from the gas pedal. CGS Motorsports makes intakes and exhaust systems for most fullsize SUVs and several midsize ones as well. One big plus you get with the CGS kit is all parts are CARB-approved and can be ordered with heat shields.
