Description
Secondary Air Injection Service Block-Off Tool – 1.8T
Seal the secondary-air port while you pressure-test or service your 1.8T. This precision-machined plate bolts directly to the cylinder head, used in place of the combi-valve perch and eliminating unwanted leaks during diagnostics, turbo swaps, or dyno pulls.
-
No-Hassle Fitment – Installs in seconds with two socket-head screws for a tight, reliable seal.
-
Built for the Job – CNC-cut billet aluminum, hard-anodized in black, paired with an OE-style nitrile O-ring and stainless hardware.
-
Keeps Tests Honest – Blocks stray air that can skew boost-leak or exhaust diagnostics.
-
Repeat-Use Ready – Durable finish and reusable sealing components stand up to repeated service sessions.
