Installation Notes and Tips

Verify right-side fitment by year, model, and build date before installation. Inspect the cylinder head surface, fasteners, and downpipe connection for damage or corrosion before assembly. Use the included gasket during installation and follow the vehicle service procedure for torque sequence and final tightening.
