Air intake systems are a common first mod to many project cars. They are quick and simple to install while also enhancing the looks of your engine bay, the sounds of your engine, and the performance of your vehicle.

Air intake components consist of air filters, vacuum lines, and connectors used to complete your air intake setup.

Pop the hood on a diesel enthusiast's truck somewhere in North America and you may find my company's logo on the engine. Welded to an intake or intercooler pipe, this logo represents an awesome responsibility to the diesel enthusiast community that has supported WCFab over the years. It's a responsibility and commitment to ensure WCFab products meet the highest standard of craftsmanship and fitment. We care enough to put our name on it.
