Colder burning spark plugs?, where do you get them Options

[nate95]

im suppose to get colder burning plugs for my nitrous kit, i went to autozone and asked for copper plugs and they didn't have any, they also said i wouldn't find any for my car? are there any other kinds other than copper that burn colder? like what about platinum? i just got some bosch platinums instead will they work? and whats with that ceramic tip on them instead of just metal?

I would change them sooner than every 15k if your on coppers. For the amount they cost, and the major role they play in your cars performance id recommend chaning them at LEAST every 10k. I would say every oil change would be ideal to change the plugs (coppers).

Also if the stores cant find "bkr7e" then ask them to find "NGK 6097". I went to 3 different stores, and talked to the parts managers at 2 of them and they couldnt find bkr7e. went back and asked for 6097, and got the right plugs.

BTW incase the parts guy doesnt know, for NGK, colder is higher number (7 is colder than 6). For most other plugs higher number is hotter. Just incase they try to tell you 6 is colder than 7.
