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.

Came pre gapped perfectly as described. Car kinda pops lil when you first start it up, totally normal. Take it for a drive and it quickly goes away. Overall satisfied with this product

Do these require a revision to a tune? I put these in and ever since I’ve been getting lower boost. Was hitting 18-20 and now hitting 13. Checked boost leaks and there isn’t any. Any help would be appreciated

I have Denso ignition coil packs, will that interfere at all?

If I need these pre gapped at 0.024 which is what my tuner recommended, can you do that with my order?

Mi auto solo tienen inlet, intake, Downpipe y tubería original directa (sin catalizadores)... Estos me sirven??? Por qué me han comentado que para autos que no traen internos de bomba y tampoco reprogramaciones, deben de ser bujias de Iridium a .033... Es correcto? O puedo usar estás .026 en mi auto casi estock?
