Title: not a PROHEAT
Review: I bought this hoping to save a little money over the PROHEAT heater. Big mistake. This heater has no PSA or ALUMINUM backing on it. I have two other PROHEAT heaters on other vehicles and they work great, down to -40F I do not recommend the Kats for engine heating , way too hard to put on. I do recmommend the PROHEAT pads. I have a model 512 CSA and a 154 CSA and now I am buying another 512 for my pickup
