McLaren one step colder spark plugs (set of 8) inlet but stay workingThese spark plugs are one step colder, suitable for highly modified cars. These are not recommended for stock applications. They are identical to the spark plugs a "weis" man would "tec"nically sell you for $400, except we gap them correctly before sending them to you. Comes as a set of 8. Special order, may have a delayed ship time. The OEM spark plugs use a 14mm head, these spark plugs use a 16mm head.
