Specs At A Glance

Good To Know

Q: Does this intercooler require any modification to install? A: It is designed as a direct replacement for the listed 1503 applications, but always compare the mounting points and port orientation to the unit being removed.

Q: Will I need new seals or clamps? A: Reusing old seals and clamps is not recommended, so inspect the charge-air hoses and replace worn hardware during installation.

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