Product Overview
The Spark Plug Tube Seal C2D3526 is a Genuine OE-grade sealing component for for Jaguar and for Land Rover vehicles with 3.0L V6 and 5.0L V8 petrol engines (AJ126 / AJ133). Also known as a spark plug hole gasket or valve cover washer seal, this seal fits into the valve cover around each spark plug tube, preventing engine oil from leaking into the spark plug wells . Over time, these rubber seals can harden and shrink due to heat cycling, allowing oil to contaminate the spark plugs and ignition coils . C2D3526 is the Jaguar part number; LR014345 is the Land Rover equivalent . Each seal is sold individually – quantity required depends on the engine (V6 requires 6, V8 requires 8) .
