Model #1325 measures 5"x7"x.075" and consumes 500watts. It is best suited for larger capacity oiling systems holding 3-6 gallons. The Duramax oil pan does not have enough flat surface area to mount this unit.

PROHEAT pads consume less electricity than frost plug/block heater counterparts. Frost plug/block heaters take hours to install with a variety of tools -- PROHEAT pads install in minutes without any tools and are permanent. A typical frost plug heater consumes 600watts while a 6.6l Duramax heater consumes 1000watts. Most applications can be covered by a Pro Heat Model # 512 which only consumes 250watts. PROHEAT pads are SMART, SIMPLE and COST-EFFECTIVE.

Dual coil design provides best performance to peak temperature, yet will not melt or burn out.

"I've found these to be the best performing plugs on the market! If your 7.3 has the late electronic controller I would advise switching OR adding a programmable glow timer or manual push button. The self regulating plug vary their amp draw and this can cause short cycles with the electronic controller." - JK

Fits 88'-94' 7.3l diesels with INDIRECT injection. Will not fit Powerstroke. This plug is a solid performer, with a long service life, but are NOT self regulating like the Dual Coil units and need to be on a properly functioning controller. Identifiable by the round "bullet" style terminal.

"The electronic controller used on the 7.3L engines will not function properly with a dual coil plug. The 4 in 1 dual coil plugs will fit these applications, but will require either a controller change or a manual push button as the factory controller will sense the amperage drop and "short cycle" the plugs." - JK
