1)The 3330's do not have the v-groove design in the center electrode.supra_10 said:Hey gang,
I have some questions for you guys, mainly on spark plugs:
MKIV.com mentions a "v-power" design. Page @:
1. Are the 3330s & 6097s of this v-power family?
2. If one searches NGK site for a spark plug per Toyota/ Supra/ 94/turbo, the part that comes up is 2978 with a .044 gap.
Any info on this spark plug and why does it seem to be "recommended" per NGK?
3. Toyota quoted me around $12/ea for their plug. Is the price justified, based on performance/quality?
I'm now @ 70M. Anything else, besides spark plugs, that needs to be replaced/serviced? Any filters, etc?
I'd like to get "street smart" and experience-based advice and not just "by the book".
I know that a service/maintanence schedule is somwhere on MKIV.com, however, I'm having hard time finding info on this site as it comes too dark on my tube.
BTW, another issue that I'm having with MKIV,com info is that pages are not dated so some of the stuff could be actually long outdated.
Thx in advance,
The 6097 looks like it has a v-groove in the center electrode, you might want to call NGK and ask them if it is really a "v-groove" design plug, here is a pic.supra_10 said:sleeper,
"1)The 3330's do not have the v-groove design in the center electrode."
Do the 6097s have this v-groove?
At BPU, should I care about this v-groove?
"2)The 2978 with 0.044 gap is for stock operation.
NGK doesn't assume you will be modding the car to high boost levels."
Are the 2978s good for BPU? To what level of boost?
Thx for your input,
