Time to change your spark plugs? Worn spark plugs can decrease performance, cause damage to your engine through misfiring and detonation and even trick you into thinking your engine has low compression symptoms. Keeping your ignition system components in good health will extend the life of your RX8 and ensures you're getting the most out of your car.
 
This set is sold as a pack of 4 plugs containing:
x2 Leading NGK RE7C-L 
x2 Trailing NGK RE9B-T
 
Compatible with all RX8s (2003-2012).
