Most of the car engines came with a hotter glow head...it has a W shaped element. They are difficult to find now days, but a standard (part # 325) "low compression" glow head will work fine.
The "High compression" glow heads have knurling around the stem. (and are part #1702 IIRC)
You can use fuel to clean the engine...you want "1/2A" fuel for Cox engines if you're gonna run it Brian. Cox engines have a steel rod running on a steel crank and a steel piston running in a leaded steel cylinder...so Cox engines require a fuel with a high % of CASTOR oil. Around 25% oil content and 20 to 30% nitro.
Cox itself officially went out of business in Feb. of this year...
Estes had it for a while, starting in 1996, but I guess it's over and done now.
There was a LOT of inventory that was sold to several different vendors..."xenalook", and "engine 049" are a couple (on ebay) that immediately come to mind... "vintage glow engines" and "coxmania" are a couple more.
Here's a place to check out for additional info on Cox engines, etc.

I recently aquired a couple of Cox Gurney Eagles...both the red and the blue versions...
Dokk...did you have anything to do with those?
