Extraflow Value Packs are a simple, affordable way to add performance. As the name implies, Extraflow assemblies move more air into an engine through the top and sides of the air cleaner; this improves horsepower and fuel economy. Filters are cleanable/reusable and, when maintained with Spectre's AccuCharge System, offer a Manufacturer's Lifetime Warranty.
Value Packs include:
