spark plug heat range

[Tia813]

I've been looking all over my local parts store for Autolite XS62 or NGK BR8EIX (the ones that come with the PAMCO)... I was successful in finding the NGK BUT it was the BR9.... The only difference between the two are the heat ranges. The BR9 is a colder plug. What can happen running a colder plug?

The worst thing that can happen with using a colder plug is that it will foul. But it isn't likely, being just one click colder.

The #9 NGK is a very cold plug. I find the NGK #7 heat range to be a good all arounder. Try to find a BP7ES NGK, these should be available and I believe they are called for in the manual. Put an R in there if you need a resistor plug.

Yeah man I had my doubts so I returned them. I did find the BR8 at Advanced Auto parts for $7 each...
