- Honda Civic Si EM1 (1999-2000)
Specs & Features
- Cast intake manifold
- Pre drilled plenum
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 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.
The BLOX Racing surface-mount vacuum provides an easy and clean installation when additional sources of vacuum are required.
BLOX Racing Performance Intake Manifolds are cast using the latest in gravity casting technology, which helps create a smoother internal plenum and runners.
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.
To add a distinct look, the intake manifold now features a raised nameplate and included BLOX Racing product badge.
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 surface-mount vacuum block provides additional sources of vacuum and can be mounted on to any flat surface. Vacuum blocks are sold separately.
The BLOX Racing Performance Intake Manifold features a larger plenum and longer runners that significantly increase the engine’s incoming airflow and volume, compared to the factory and some other aftermarket units.

All BLOX Racing Performance Intake Manifolds are designed to accept factory or aftermarket throttle bodies, and reuse all factory sensors.
For maximum results, use with a BLOX Racing cast or billet throttle body, air filter and velocity stack.
