I have a 95 legacy LS. Looking to add a Block heater. I saw a Subaru part number A0910AS100. Any thoughts? does it work. Are there better out there? how is the installation.

 

thanks,

i put one on my 99 OBW, i installed it during a coolant system flush, unscrewed the plug, screwed it in and ran the wire out the front behind the licesnse plate...piece of cake. i like it because on the 18 degree mornings it gets rid of the annoying piston slap. and in about a quarter mile i have warm air.

The stock subaru block block heaters work great. Since it's a screw-in design and most others not, I doubt there are aftermarket ones available.

 

I would recommend installing a stick-on oil pan heater at the same time.
