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?

>
those plugs are junk and if you are going to run nos then i would stay with the ngk as at least the were made for your car the bosch are a little hotter and will burn out very fast

other than copper what would be a colder plug? iridium? or what?

bkr7es-11 plugs...

or go to napa and give them the part number

1 step colder
BKR7E
2 steps
BKR8E

what Dan told me when I was trying to find out the exact same thing. Just walk into Napa and give them the part number, they look at you funny at first because you aren't asking questions but they do have the plugs at Napa.

>"Colder" or "Hotter" plugs have nothing to do with the material that they are made out of. It has to do with the ability of the electrode to dissapate heat inside the cylinder to avoid pre-ignition and hot spots on the plug itself.

"Colder" plugs can dissapate more heat away from the electrode. In non-modified cars, this can lead to fouling and poor running with build up, but in modified cars that run higher cylinder pressures than stock (nitrous, aftermarket turbos, increased boost on stock turbo engines, etc) the plugs work correctly, don't overheat and don't foul.

The stock 3s-gte should use NGK BKR6E (or BKR6ES) plugs. One step colder plugs are BKR7E. These are popular plugs in many import cars (My WRX uses the same plugs...).

For high-performance, nothing beats copper (standard) plugs. All other spark plugs are designed for longer life, not higher performance. Make sure you change your plugs every 10-15k miles if you use coppers...

Hope that helps...

thanks a bunch

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.

ok thanks guys, also my brother has a supercharged GTP and is looking for colder plugs to will that same part number work for his car to?

no a set of champions or autolite will work good for him , i dont know the part number right now

Why is he looking for colder plugs? Only go with colder if you need them. Just because his car is supercharged doesnt mean he needs it, unless he iss running more than stock boost, or upgraded something that would increase his cylinder pressure/temp

ya hes going to be running more boost, hes gitting the smaller pulley for it, and new PCM and other stuff. so he needs some.

go to ngk's website (ngksparplugs) and look up his car

and then find whatever plug the stock NGK plug is
and add 1 to the heat range

for example...stock plug is IFR6AIX-11
then the colder plug will be IFR7AIX-11 (heat range 7 rather than 6)

and then go on www.clubplug.net and look for IFR7AIX-11
once you find it, add it to your cart...
now go to the cart and see what the 4 digit NGK part number is for that plug

Take that number and go to napa and get your plugs

wow, ok thanks a bunch that really helps us out!

"teach a man to fish" type of deal...

I use NGK V-Power grade 8. All the fast guys here use, also.
