Description

Details

A redesigned cast alloy inlet plenum that allows improved airflow resulting in power gains of 10-25 bhp depending on engine spec. Uses the original 60mm throttle body and inlet manifold (both not supplied) and is supplied with a new throttle bracket and butterfly lever. Suits engines with 300+ bhp but better results will be seen on 400+ bhp engines. The issue with original plenums is that they don't supply an even distribution of air to each cylinder meaning that whilst one cylinder's mixture is fine, another could be rich because it is getting less air. This becomes more critical with increased performance of the engine. The modified plenum uses a high air flow venturi design to supply an equal amount of air to each cylinder. Machined with O ring sealing joints for both manifold and throttle body faces. Made from a strong alloy casting which will not split under high boost pressures, unlike welded manifolds. Supplied with hardware kit.

Note about fitment: if you compare this plenum with an original item, you will notice that the throttle body is positioned further forward. For red top engine applications (2wd & early 4wd Sapphire), the power steering hose will now foul the throttle body. A revised flouro-lined PAS pipe is available to get around this problem. For all applications, you will also need to adapt (usually with an additional pipe adaptor) the intercooler to throttle body pipe as it will now be at a shorter distance.
