Inlaatspruitstukpakking dicht de verbinding tussen de bovenste plenumkamer en het onderste inlaatspruitstuk op de EFI Rover V8-motor af.

Het vormt de luchtdichte afdichting over het plenum-naar-spruitstuk-vlak, waardoor ongemeten luchtlekken worden voorkomen die het brandstofinjectiemengsel en de stationaire kwaliteit zouden verstoren. Gemonteerd op de Rover V8 EFI benzinemotor.

Frequently asked questions

What does the ERR6621 plenum inlet gasket seal on an EFI V8?

The ERR6621 gasket seals the plenum chamber to the inlet manifold on 4.0L and 4.6L EFI V8 engines, preventing air leaks into the intake tract. Air ingress here upsets fuel mixture and idle quality. It fits the Discovery 2 (V8 petrol) and Range Rover P38 (1994-2001).

What are the symptoms of a leaking plenum gasket on a V8?

A leaking plenum gasket typically causes rough idle, hesitation under throttle, and a hissing or weak vacuum at the intake. On EFI V8 Land Rovers, unmetered air past the plenum seal can trigger lean mixture conditions and poor throttle response.

Does this gasket fit the Range Rover P38 diesel engine?

No. ERR6621 fits V8 EFI petrol engines only, specifically the 4.0L and 4.6L units. It doesn't fit the P38 with the 2.5L BMW diesel, which has a completely different inlet manifold design.
