What This Product Does

The rubber sleeve forms a flexible, sealed connection within the inlet manifold assembly. Maintaining this joint helps prevent unwanted air entering through a damaged connection.


Functions

  • Connects adjoining intake components.
  • Seals the inlet connection against air leakage.


Technical Details

  • Part reference: 91111088502
  • Brand: OE Match.
  • Construction: rubber sleeve.
  • Fuel injection application: K-Jetronic.
  • Diagram engine/model designation: 911/911S.
  • Vehicle requirement: six sleeves; this does not indicate a six-piece pack.


Symptoms of Fault

Inspect the sleeve for splits, hardening or damage around its connections. An intake leak may accompany an uneven idle, hesitation, stalling or a hissing sound. These symptoms can have other causes, so confirm the source before replacing parts.


Why Replacement Matters

Renewing a deteriorated sleeve addresses a potential air-leak path in the intake assembly. Check the adjoining connections and clamps during installation, as worn supporting components can leave the joint improperly sealed.


FAQs

What should be checked before fitting?

Visual inspection and an intake smoke test can help locate a leaking connection.
