Get that badly needed top end power into your Subaru. We put the STi onto the rollers and picked up 35hp from the Sheetmetal Intake Manifold! HP increased from 305 to 341AWHP!

Did you WRX guys feel a little bit left out because we only made an intake manifold for the STi? Well, we didn't forget about you. The WRX Sheetmetal Intake comes with CNC machined endcaps, with CNC radiused runner inlets, formed one piece plenum and Mandrel bent runners. It will accommodate the Idle Air Control built into the Stock WRX throttle body, and the throttle cable. Get that high RPM power that you've been craving!

Magnus Subaru Sheetmetal Intake Manifolds - Short Runner

These manifolds are a direct replacement to the stock manifold, and continue to utilize the tumble generator valves (TGV).

	Subaru USDM STI Intake manifold- short runner	$1095.00
	Subaru USDM WRX Intake manifold - short runner	$1095.00

Magnus Subaru Sheetmetal Intake Manifolds - Long Runner

These manifolds are a direct replacement to the stock manifold, but eliminate the tumble generator valves (TGV). We compensate for the thickness of the TGV by adding length to the runners, which keeps the throttle body in its stock placement.

	Subaru USDM STI Intake manifold - long runner, TGV delete	$1195.00
	Subaru USDM WRX Intake manifold - long runner, TGV delete	$1195.00
	Subaru JDM/EURO STI and WRX Intake manifold - long runner	$1195.00

Heat Barrier Gaskets

Magnus' heat barrier gasket replaces the stock gasket and forms a heat barrier between the intake manifold and the cylinder head. This dramatically reduced intake temperatures.
