NGK Plugs for racing?

[Dan M]

NGK's website is... not very informative. Summit racing has a part number for a "Spark Plug ``B10EGV`` Racing Plug" NGK-5927

On their website, NGK says that these plugs are designed for higher tolerances. I think I'd like to go this route. Any thoughts?

I'll rephrase... has anyone heard of these before?

I have heard of them, kinda pricey arne't they.

I have used, Accel U gooves, Bosch platinum splitfires, and AC Delco Rapidfires. Notice no difference.

Basically,

Unless you are running Nitrous, or forced induction I wouldn't think your plugs are that important enough to change them, unless you need a tune up.

Or if your engine chronically cracks them? [img]tongue.gif[/img]

I was thinking a plug with higher heat tolerances might last longer than 4-6 months for me.
