440 Ignition Coil & Plugs
Thanks! So they current plugs installed at Champion RJ12YC
From a Google search, these are a #12 heat range plug
Using that link, the two NGK plugs are much, much different:
3332: #5 heat range (V Power)
3522: #6 heat range
At NGKs website, the cross reference for the RJ12YC is the #2298 plug and the #3332 plug
