Hi all, ordering the EZ Heat sump pad for my RV-8 and Spruce lists the 440 or 441 as applicable for the O-360. Anyone know which one fits better?

I have the 440 on my O-360. It fit very nicely. I cant speak to the 441, because I never tried it.

That’s exactly what I needed to know, thank you. The two are just a bit different dimensionally, will be ordering the 440 today.

The 440 heat pad did not fit my O-360-A1F6. Sent it back.

Mine is an O-360-A1A...

I bought a smaller square one for $90 on amazon.ca. I think the brand name Polar from Canada. Seems to work good and sticks very good. Same adhesive and silicone sealant.

My hangar neighbor bought this one which was way cheaper still ($25) and uses the same adhesive and sealant that came with my $163 AC spruce unit that I’d sent back.
