Ford Falcon BOSS V8 5.4L High-Volume Inlet Plenum & Twin-Blade Throttle Body for BA BF FG FGX Falcon XR8 BOSS 260, 290, 302 & 315 Engine

* Includes Throttle Body *

Planet Parts' High-Volume BOSS V8 inlet plenums are designed for both street & track purposes. Our BOSS plenums give performance gains to N/A and boosted setups. They are an absolute must for ANYONE looking to increase the performance of their Ford BOSS 5.4L V8.

Even though these manifolds are the absolute best value on the market, we haven't taken any shortcuts on quality. Each manifold follows a strict manufacturing process - after casting, they are heat-treated for strength & shot blasted smooth. After that, the plenums flat surfaces get machined to mirror finish for a flush fitment. Then each unit is tested to hold 40psi of pressure before finally being safely boxed up and sent on its way to you!

Our High-Volume inlet plenums are supplied in a smooth cast iron finish - perfect to either install right away or get painted in your preferred colour!
