I'm just winging it as far as A-B-A testing and such. This isn't a mod you can easily remove and reinstall. OTOH, I think it's a no brainer that it would help reduce heat loss. I think heat loss is a more visible issue for those of us who do lots of EOC and who have reduced overall engine use and output. Or if using a block heater.

I've been watching it carefully for heat deterioration and it seems to be holding up just fine. As the weather warms up in spring and summer I'll watch it closely again.

As I now use a block heater daily i'm paying attention to heat loss from the engine. My block heater takes forever to do its job so I figure anything I can do to reduce heat loss while heating up is a good thing.
