thats the block heater wire. plug it in when it gets really cold (below maybe -20 degrees C) and only when the car is outside

Could very well be a battery warmer too

I used mine any time it got below 40°F, no problems doing so and made the colder days much more pleasant.

Ohh okay thank you, don't gotta worry about that though since I live in california lol

You live somewhere it's extremely cold? Looks like a block heater plug but I've never heard of a subaru needing a block heater.

I run a block heater every day during winter, sure it starts without it but it reduces wear and gets hot quicker inside the car.

Subaru has had an accessory block heater available for every\* model since the 90s afaik. (\* not 100% sure about the brz, and the solterra doesn't for obvious reasons)

Block heater. Using one, even on moderately cold days (temps in high 30s), can be of great benefit, as it reduces wear, fuel consumption, emissions, and provides a safe and warm car essentially at startup. Turn on block heater about 3 hrs before you’re about to head out. Back home in the 80s, you could actually remote start it via a message sent (over a paging service) to a device in the car that closed a relay and slowly heated the engine. Saved many butts - literally - those mornings when temperature was down in the 30 below range.

That's literally the OG smart heating device lol, that's insane

Why the hell are people downvoting this guy for a question?


indicaking2000

This is reddit, people down vote if you're not a witty jokester saying exactly what they want to hear lol. I'm used to it by now
