Actually, I just can't leave well enough alone. Plus, I have a soft spot for NGK's.

Btw, as Arthur & Gilly says, the part for Bosch changed from F9DC0 to F8DC4. And the Bosch website's part finder lists the new F8DC4 for my car. So which should I do? The old with the "0" or the new with the "4" (Extended insulator nose)? And why did they change the recommendation to the colder heat range?
