I have just installed kit TSP4CYL-2925-115 on my O-320-D2G for colder overnight temperatures here in my new home state of Tennessee.
I found this to be an extremely well made product with very nice weatherpack connectors. I liked this kit with its heated bolts that replace one of the intake pipe bolts on each cylinder, plus a pad for the sump.
I also purchased their mounting kit TU01062 to mount the power plug to the oil dipstick tube. I used a piece of 1 inch heater hose as a grommet around the dipstick tube rather than their method of winding self vulcanizing tape around the dipstick tube. The heater hose slit down the middle worked perfectly as a grommet for the two hose clamps on the power plug bracket.
The wiring was very high quality enclosed in sheathing. I mounted the distribution connector to the engine mount behind the engine baffle using two Adel clamps. I also wrapped the harness to each side of the engine in spiral wrap conduit for a cleaner installation.
The current draw is only 2.1 amps at 120volts for 250 watts. After plugging in overnight, the entire engine and cowling area was at 100 degrees. All metal was warm to the touch. Engine oil was at 100 degrees.
This is an expensive kit which can be used on certified aircraft. I am very satisfied just the same with the quality and the performance of this system.
