We have about 240 of the Denso 41-983 (AC number) original 496 OEM platinum plugs and we are selling them in sets of 8 for $7.00 per plug plus UPS shipping. they should be gapped to .060". If anybody is interested, call us @866-496-8181 or email to [email protected].

Denso's SUCK plain and simple,,, after many years of racing and never popping a plug I went cheap and bought a few Denso's first lap out on the track in practice popped one plug, second lap on the track popped the second plug. I wouldn't use them in my lawn mower !! NGK all the way.
