Want a quick and easy way to boost your truck’s horsepower and improve your fuel efficiency? Try installing one of our cold air intake systems for your Chevy Silverado or GMC Sierra (5.3L V8 engines, 2014-2018 models). By replacing your stock air intake, you can increase your engine’s performance by an average of 12 horsepower (or 14 horsepower measured at the wheels). Plus, you’ll also improve your gas mileage by making the combustion cycle more efficient. No brainer, right?
