I have several sets of plugs here... some Bosch W5DC plugs and some W7DC plugs?
I know that the numeral in the part number is the heat range - but what does it mean to me and my little /6 cylinder monster?

I've got three sets of W5DCs here. I called my FLAPS and they told me that W7DCs weren't available anymore. Does anyone know if the part number was superceded? The kid on the other end of the phone got confused when I asked him. -Rusty |

For Bosch, the higher the #, the slower it transfers heat (hotter plug). If you do nothing but race, then the 5's are good. I usually stick with 7's for street use. Sometimes even 8's. My favorite plug bosch makes is a W7DTC, grab some, you will see why I like them. |

Thanks for the info. Okay... I'll bite. Why? |
