Specs At A Glance

Good To Know

Q: Should I have the head checked before installation? A: Yes, having a machine shop verify flatness and pressure-test the casting is a smart step before bolting it on.

Q: Are new head bolts required? A: Most 1.4L turbo applications use torque-to-yield bolts that must be replaced rather than reused.

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