NGK spark plugs..

[666 the legend]

NGK is a great plug but..I use the CHEAPY Denso $1.98 plug [gap .35]in my NOVA..[970 HP N/A] and it starts up everytime and havent changed a PLUG since last May..!! is 9.50 ET all day long..at 3,600 lbs..!!

Are the iridium plugs worth trying?

[666 the legend]

I try whatever WORKS...!! as long as you have the RIGHT HEAT RANGE...and it runs GOOD and DEPENDABLE...Thats all that matters to me...

I need to replace the plugs in my Wifes car and after reading this I'll give the NGK's a try. Does anyone know which plug would go in a GM crate engine 454/420HP, iron head? I'm pretty sure that wouldn't be in the NGK catalog.

A couple side notes to the superiority of NGK plugs;

Not sure if the same in the States or not but new offshore produced vehicles coming into Canada sometimes show up with Champions installed as 'original equipment' instead of the actual spec NGK's to save on import taxes!.
I believe they ship the Champ plugs and a few other simple items from here to Japan or wherever the production plant is so a lesser percent of the car is considered produced offshore hence the lesser import taxes.. Of course the Champs run like s**t in many applications and are quickly changed to the spec NGK's by service techs in the know.. This isn't publicised by the manufacturers for obvious reasons also not spread to the dealer level either to keep them from changing them under warranty!.

Also to NGK's credit, they're all I use on the old two-stroke racing snowmachines anymore too.. With mixed or injected oils, Champs and others foul very quickly in comparison to a set of NGK's!.

I've also got the NGK's in the outboards, I think the little boat's plugs are three or four years old and it always cranks on half a pull.

What part no. would be correct for my stock 302 as the ngk weblink does not have all the correct engines listed?
