Air Intake and Fuel Delivery Parts

Your factory intake and exhaust systems are typically the biggest bottlenecks preventing your vehicle's engine from performing at its peak. Performance exhausts work best when paired with a free-flowing air filter or performance intake system. While you're here, check out Pep Boys' selection of intake manifolds, carburetors, air filters, and performance air intake kits for domestic and import cars and trucks.

For most enthusiasts, installing an exhaust or performance intake is a simple, DIY job that can be done under in a morning or afternoon’s work, however if you want help from the pro’s, visit your local Speed Shop for advice, parts, and installations.
