Roo Racing Secondary Air Pump Block-Off Plates (EJ Engines)

The secondary air pump system on later-model EJ engines is a common failure point — stuck valves, broken pumps, and constant CELs that leave cars in limp mode.
This kit removes the system entirely and seals the ports correctly using Australian-made stainless steel block-off plates.

Perfect for owners deleting the system during ECU calibration or when hard faults make repair uneconomical.

Why this exists

• Secondary air pumps regularly seize or trigger faults

• OEM replacement parts are expensive and increasingly hard to source

• A proper block-off solution prevents exhaust leaks and repeat failures

• Ideal when the system is disabled in the tune

Features

• ✅ Direct bolt-on plates to replace the factory SAI valves

• ✅ CNC-cut stainless steel — no warping or flaking coatings

• ✅ Australian-made in small local batches

• ✅ Fits all EJ engines originally equipped with a secondary air system (2005+)

Fitment

• EJ20 / EJ25 turbo engines with factory SAI

• WRX / STi / Forester XT / Liberty GT (2005 onwards)

Important:
This mod requires the air pump system to be deleted in the ECU calibration by a tuner.
Intended for off-road / motorsport applications.

Removing failure points is just as important as upgrading the rest of the package — especially as these cars age.
