Installation Notes and Tips

Install on the right side only. Verify vehicle year, make, model, and engine-side application before installation. Clean the mating surfaces thoroughly and inspect the cylinder head flange, studs, and exhaust connection for damage before assembly. Use the included gasket and hardware during reassembly to help achieve a proper seal.
