PLM Power Driven B-Series Throttle Body B18 B20
The B-Series 70mm throttle bodies are 10mm larger in diameter than the OEM 60mm Throttle body. The throttle bodies are precision die-cast 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 powerband on naturally aspirated applications and even more on forced induction ones. This results in a larger opening for incoming air and dyno proven 12-15 WHP gains (modified engine with port matched intake manifold opening). Some vehicles may require customizing of coolant lines. We recommend port matching the intake manifold to have the best result.
