Response to spark plugs

The Autolite 45 is the sub for a no longer available 42. The 32 is a colder plug but to confuse matters more the AR33 (racing) plug is the same as a BF22. I don't know if there is an Autolite match for the 32 and couldn't find any listing for a Powertip 35 so we haven't answered your question so far.
