S2 spark plugs same as S1?
 

Hey All,

I just wanted to be sure that the S1 and S2 spark plugs are the same. I have read the S1 DIY install thread and some S2 threads but I just want to be sure that the plugs are the same before I order some on amazon.

My concerns come from putting in a 2010 R3 on advance auto parts website and NOT getting the NGK 6700 and 6701 but putting in an 04 base and getting the NGK plugs.

Thanks for not flaming!

The plug specifications are the same. Have you consulted your owners manual? If you don't have one, they are available on the Mazda website....
