Filters & Caps

Filter and Cap Resources

A clean filter is essential to keeping your vehicle’s systems running smoothly and efficiently. Filters are designed to trap the harmful contaminants that could enter your vehicle, and allow your vehicle’s fluids to flow through and lubricate integral car parts. Pep Boys carries a wide range of filters for your vehicle including air filters, fuel filters, oil filters, cabin air filters and more. For the Speed Shop customer, we carry a variety of filters, filter wraps and other performance items. Pep Boys offers filter replacement services including a free air filter installation. Free air filter installation is also included in every oil change service package. Whether you are a do-it-yourselfer or prefer to let the professional take care of it, Pep Boys has the filters, caps and components you need for your vehicle online and in stores!
