Why Replacement Matters

Renewing a damaged sleeve addresses leakage at this intake joint. A hardened or distorted sleeve may no longer seat correctly, even when its retaining hardware appears secure. Check the adjoining housings and clamps during replacement so that damage elsewhere does not leave the connection leaking.

FAQs

How can I check whether the sleeve leaks?
Look for cracks, distortion and loose connections. An intake smoke test can help locate leakage that is difficult to see.

Should the clamps be inspected too?
Yes. Check their condition and seating, and renew any damaged hardware using the correct specification.

Does rough idling prove this sleeve has failed?
No. Ignition, fuelling and other intake leaks can produce similar symptoms; establish the cause before replacing parts.

Check fitment for your specific vehicle (model, year, engine) before ordering.
