Autolite 295 for those needing a long reach plug.

I use AC plugs, R45XLS in the 170 or long reach D17 and use R45S in WD45 and short reach D17.

Actually, the Autolite 295 is the 3/8" short reach plug.

yeap dan thats correct . the only time i would run the 3/8 reach plug on either the 3 or 4 inch head is if i was oil fouling the plugs . the heads sparkplug hole is made in fashion of a good antifouler when the 3/8 reach plugs are use . on the 3 inch head you cant use the projected tip . the electrode will hit the backside of the plug hole casting in the head . if you desire a projected tip plug for the 3 inch head my recomendatiomn is to look at the .708 reach plugs they have worked for use on the 3 inch head well in the past. I dont have any plugs in stock cant compete with autozone or orielys.
