Installation Notes

Verify the engine calls for BCPR6ES specifications before installation. The pre-gap is .036 inches, but several listed vehicles require a different gap setting, including Saab 900, Saab 9000, Toyota Supra, and Aston Martin Virage applications. Always confirm the required gap from the vehicle service information and adjust as needed before tightening to the correct torque. Check thread diameter, reach, seat type, and terminal style against the original plug to ensure proper fitment.
