Carburetors And Intake Manifolds

Whether you're carbureted or fuel injected, a big block or 4cyl, Pep Boys can help feed your need for speed.

If you are looking to upgrade your carburetor due to age, damage or appearance, things such as engine size, internal engine components, intake manifold design, and intended use of vehicle are key to making the proper carburetor selection. No matter the vehicle, Pep Boys has the carburetor that's right for you.


Pep Boys offer performance carburetors from companies like:


  • Demon
  • Edelbrock
  • Holley
  • Jet
  • Proform


Intake Manifolds come in two basic types: single and dual plane. Dual plane manifolds offer good low-end torque and are usually found on street cars and normally peak out at around 5000 RPM. Single plane manifolds, usually associated with performance, offer reduced low-end torque but provide good mid range and upper RPM limits to 8000-8500 RPM and higher.

The best way to select an intake is based on what you intend to do with the engine. Pep Boys can help determine the best manifold intake for your vehicle.

  • Ford Racing
  • Professional Products
