Block heaters
 

So last winter my car seemed to run like shit in the winter compared to the summer especially as it was warming up (Naturally aspirated, not tuned). I was wondering if any of you guys run a block warmer or know where I might be able to get one specifically for the miata for those sub freezing mornings coming up.

I am not aware of any miata specific, but I have used ( at various times on my cars) a generic one that is magnetic and I have also used a dipstick that plugs in and keeps the oil warm. That particular one worked well while wintering in Vermont.

Would something like this work ok?
