IMPORTANT INSTALL NOTES - READ BEFORE PURCHASING  ? Header Spark Plugs \u0026amp; Heat Shields REQUIRED for Proper Fitment To ensure proper clearance, you MUST use Header Spark Plugs and plug wire heat shields. Standard spark plugs WILL have clearance issues. Recommended Spark Plugs: * Accel 0576S (Taper Seat) * Accel 0414S (Gasket Seat) Plug wire heat shields are also strongly recommended to prevent heat damage. ? Failure to use the correct spark plugs may result in fitment issues and difficulty during installation. ?
