Spark Matters. Using the correct spark plug is a must for nitrous powered vehicles to ensure maximum performance and reliability. A good rule of thumb is to run one step colder plug per each 100HP added over stock. If you are unsure about what spark plug is right for your application contact a Nitrous Outlet tech specialist at 866-648-7637 and we will help you find the perfect plug for your application.

Application. This plug is 1 step colder than a stock 5.0 Coyote, 2 steps colder on a 6.1L HEMI, and 3 steps colder on a 5.7L HEMI. These plugs should be gapped at .032".
