B, D, F, H Series Pro 74mm Throttle Body

PLM Pro throttle bodies are designed to be used with factory intake manifolds as well as aftermarket intake manifolds for bolt-on horsepower and torque gains by optimizing engine airflow, all at a competitive price.

The B-Series 74mm throttle bodies are 14mm larger in diameter than the OEM 60mm throttle body. The throttle bodies are precision diecast from high-quality materials with an idle adjustment screws for fine tuning.

Each throttle body features an oversized bore, which results in significant horsepower gains throughout the power band on naturally aspirated applications and even more on forced induction ones. This results in a larger opening for incoming air and dyno proven 15+ WHP gains (modified engine with port matched intake manifold opening). 

We recommend port matching the intake manifold to have the best results. Some vehicles may require customizing of coolant lines as well.
