37.5mm X 8mm Valve - T2 - 1975-79 - 2.0 Type 4 Inlet Valve - CJ Engine Code

This replacement inlet valve is designed specifically for Volkswagen Type 4 2000cc engines with CJ engine code, as fitted to Baywindow Buses from August 1975 to 1979. It is also suitable for other 2000cc Type 4 variants using the same inlet valve specification, including GD and GE engine codes.

The inlet valve controls the flow of the air–fuel mixture into the combustion chamber. Accurate valve dimensions and material quality are essential for correct sealing, efficient combustion, and long engine life. Worn, burnt, or pitted inlet valves can cause poor compression, loss of power, rough running, and increased fuel consumption.

Manufactured as a quality reproduction, this valve matches original specifications, featuring a 37.5mm valve head, 8mm stem, and an overall length of 117mm. The valve includes three keeper grooves, ensuring correct compatibility with original valve collets and retainers. It is ideal for cylinder head rebuilds, valve replacements, or routine engine overhauls.

These valves are sold individually, with four inlet valves required per engine.
