need to at least regap plugs for use with CDI box..... so i figure i will replace them while im at it.....
i have bosch supers in there now....
im gonna try the NGK's... im told either the bp6es or bp7es....
only difference is heat range correct?
what do you guys recomend....
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.

Well then there ya go! You need NIPPLES.
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.
Which runs cooler the 6 or the 7 - I have a set of both, but can't remember

so whats the "P" for?
My local shop looked up the plugs for a 914 in his NGK book and it said
B6ES for 914
BP6ES for 911

hmmm...now im more confused....
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.
