Installation Notes and Tips

Confirm the vehicle is one of the listed front-position applications before ordering. This converter does not require a gasket, and Davico notes use of Decarbonizing Induction Kit 1540ea with this part. Because emissions regulations vary by state, review local requirements before installation, especially for California and New York emissions-system restrictions noted in the fitment data.
