for sale are four (4) NGK one step colder spark plugs, LFRAIX6-11. these plugs are brand new and still in the box. i had a misfire issue with my car and thought i cracked a plug, so i ordered these and figured out the problem (intermittently bad coil pack) before they arrived so now i don’t need them anymore. i ordered these plugs from swerve and paid $34. i’m looking for about $30.
