I dunno if the lack of K in the part # matters.

According to NGK’s part guide:

> **[partnumberkey.pdf](https://www.ngksparkplugs.com/techinfo/spark_plugs/partnumberkey.pdf)**

K = 2-ground Electrodes.

The BKR7EIX cost me $12ea. What are these costing you?

well compare to your stock ones then… if the length from the seats is the same, then they’ll work with the proper gap… The only thing people are scared of when using the wrong spark plug is when they’re too long which might hit the piston, or too short which won’t fire the mixture properly and bad combustion.

Oh… and also the heat range. If I remembered right the 6, 7, 8 represents different heat range. That’s going to affect your performance too.
