BLOX Racing intake manifold version 3 (Honda B18C4 engines)

The BLOX Racing Power Intake Manifold features a larger plenum and longer runners which significantly increases the engine's incoming airflow and volume compared to the factory and some other aftermarket units. Each intake manifold has been balanced, pressure tested and tuned to create more usable horsepower across a wider RPM range.The intake manifold's overall weight is also greatly reduced. In addition, the IAC port has been relocated in order to accommodate throttle body match-porting up to 72mm.

The BLOX Racing Version 3 intake manifolds feature a pre-drilled plenum that accommodates the surface-mount vacuum block without the need of drilling or other modifications.

Recently introduced, the BLOX Racing Version 3 intake manifold features pre-drilled holes on the nameplate that accommodates the new BLOX Racing surface-mount vacuum block. The surface-mount vacuum block easily bolts on top of the nameplate providing a clean and hassle-free installation. However, the name badge can be applied if a vacuum block is not used.

The BLOX Racing surface-mount vacuum provides an easy and clean installation when additional sources of vacuum are required.
