Mazdaspeed NGK 1-Step Colder Spark Plugs - Set of 4

One of the most crucial components of the Mazdaspeed engine are the spark plugs! Much like the Mazdaspeed HPFP internals, correct heat range and high quality spark plugs are needed when modifying your Mazdaspeed for higher than OEM power levels. With increased boost pressure and turbo sizes, a 1-step colder spark plug is recommended for peak performance.

CorkSport is helping you take the guess work out of choosing the proper spark plug for your Mazdaspeed build. CorkSport now has pre-gapped NGK 1-step colder plugs ready to buy with your other CorkSport goodies.
