Solves the space problem I had with the EZ Heater pad touching my new Powerflow exhaust collector. These are small enough to mount one on both sides of the oil sump.

I received my order in a timely manner, although I haven’t installed them yet on my O-360 powered RV6 kit. I have used these sump heaters before and prefer them because of their size and ease of installation. There isn’t always a lot of open real estate on the bottom of the oil pan, but I’ve always been able to find a spot for these - and they work great in service.
