If I remember correctly NGK higher number colder, while Champion lower number is colder.

(Actually I have a large drawer full of them from the last 735 hours of operation!) These are the factory NGK BUR7EQ and 9EQ (cheap). If I were to try a colder plug, I am stumped on the listings about what to try and which will fit without grinding off those ears on the rotor housing. Could you steer me to a part number that I could try? No liability, I promise. Bill Eslick 13B NA The higher the number on NGK plugs the colder the heat range. Try the 10s in fine wire if you can find them. I use 11.5s to race on. But $25.00 each is a bit steep. I had some Champion N-57Gs and N-82s I was using. The 82s are a bit hotter but caused no trouble. Any cross to the N-57G heat range would work fine. NGK B10EGV Is the cross for the Champion and has the gold Palladium fine wire tips. _http://www.championsparkplugs.com/sparkplug411.asp?kw=Heat+Range+Interchang e+%28NGK%2DDenso%2DChampion%2DBosch%29&mfid=2_ (http://www.championsparkplugs.com/sparkplug411.asp?kw=Heat+Range+Interchange +(NGK-Denso-Champion-Bosch)& mfid=2) Here is a nice site with crosses for heat range. I will find those Autolight plugs and get you that number. Lynn E.
