Good To Know

Q: Can I fit this sleeve without machining the head? A: No, a valve seat sleeve is pressed into the head and then cut to the correct seat angle, so machining by a shop is typically needed.

Q: How do I confirm it fits my GTI 130? A: Check that your machine runs the 1503 engine and match part number 420256606 against your model year and parts diagram.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
