Yep only difference is heat. I'm using the BP6ES right now. Don't let them sell you the BPR6ES. It's a resistor plug and you cant pull the little metal cap off of it so the plug wires wont go on. Ask Scott how we know this. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

what is the heat range of your current Bosch plug, and do you want to go hotter or colder than that ?
*generally* you want to run the coldest plug that you can keep from fouling. the CDI should let you keep a colder plug clean, as well. so i'd try the NGK 7's, especially with summer and track events coming. watch 'em for fouling tho. |

Bosch are colder with smaller numbers (e.g. 5 is colder then 7) NGK runs the other way - bigger numbers are colder (e.g. 7 is colder than 5) yes, it's confusing. i ran NGK 8's in my /6 on the track, with (IIRC) 140 mains and open exhaust... |

Hey Aaron: Really only 3 things to worry about.
1 Thread Dia. 2 Length 3 Heat Range You have got the first two down (not by choice). Number 3, you going to have to learn to read them, sandy brown, tan. Its is the color of the porcilen(sp). the deeper you look into the pulg the better. If they start to get to dark go to a hotter plug. NGKs as stated above the higher the number the colder the plug. NGKs are cheap, find the heat range you want to run with them, if you still fell the need to put in high doller plugs, do it after. Oh yeah, NGK makes thoes too.
