XF EA-AU BA BF FG Falcon 4L Barra SOHC Intake Manifold Plenum

Description

Forward Facing Intake Manifold Plenum to suit XF EA EB ED EF EL AU BA BF Falcon Barra and SOHC 4L. Proven bolt-on power gains for the same boost level. Forward facing throttle, made from cast alloy.

These plenums are designed to fit the stock lower inlet runners from EF-BF SOHC & Barra Falcons with minor changes (holes drilled to 10mm). Key features include:

• Fully designed and cast in Australia!
• Shorter, neater intercooler piping
• More power on the same boost level
• Flows more air than the stock manifold
• Allows room for the injectors/fuel rail to be removed without unbolting the plenum
• Heavy duty cast alloy construction, will not crack/split under high boost
• Cast alloy finish can be painted, powder coated, sanded/polished
• Fits standard SOHC EA-AU cable & Barra BA-BF DBW throttle body (FG option available)
• Has MAP sensor mounting boss to fit AU-BF MAP sensors (can be blanked for use on EA-EL)
• Supplied with vacuum fittings supplied and all bolt holes tapped
• Suitable for high powered N/A applications as well as forced induction

The Skid Factory guys have put the R&D into this new plenum, and they provide proven results on the dyno and track.

This plenum is fitted to the Hackshop Garage Turbo Fairlane. Running a rebuilt stock SOHC, the car made impressive power through a massive histall on the dyno.

When fitting a similar plenum to a Barra FG Falcon, we’ve seen it go from 300rwkw with the stock manifold to 325rwkw with a plenum and slightly less boost! The Barra has since run a 1/4 mile of 9.98@135mph with 460rwkw at the time. Similar plenums have also made 430rwkw on 23psi boost on a SOHC, and BAs and BFs have gained 20-40rwkw on the same boost. They even work great on N/A cars; we’ve seen a BA Falcon pick up 14kw up top from fitting a plenum.

Fitment

These plenums fit all manifold models from XF-FG. EA-ED must use EF-AU manifold lower runners, available cheaply at wreckers. For BA BF Throttle Body (65 x 65mm) see our Throttle Body Loom Extension kit (available through T.I. Performance). For all models, grab our Forward Facing Thermostat Kit to move the radiator hose out of the way of the plenum. For FG Throttle Body (65 x 75mm) make sure to order the variant with FG throttle body bolt spacing. See other listings for fuel rails and injectors to suit. For XF it is recommended to use an FG throttle body to provide extra clearance to the bonnet & inner guard.
