• Heats entire engine
• Use an extruded aluminum construction that is durable but also lightweight (13 oz). The size of the unit is either 5 x 4-5/16” or 5 x 2-3/4” (depending on model). Models can be used for over 600 Lycoming and most Continental engines as well as some Franklin, Garrett, and Marathon.
• The pre-heater is impervious to puncture and contaminants.
• Can be reinstalled after overhaul or to another engine.
• Can be left on continuously (the heater is thermostatically controlled: 170- 200 deg. F.).
• The heater will never overheat. A thermal fuse shuts off the heater should the heater ever become dislodged from the sump and the thermostat fail.
• Can be used with portable generators.
• 220 watts; two, 110- watt heater cartridges in parallel.
• Extremely simple installation. Installs with a 2-part epoxy (included) that is heat cured when unit is plugged in.

• Minimal paper work. Installation is considered a minor modification with no STC or 337 entry needed. Simply make a log book entry.
• FAA/PMA approved.
• Two-year, unconditional guarantee; the best in the industry

Lycoming IOs w/air intake on bottom (IO 360A1A, for example); for engines where a smaller footprint required; typically mounts on side of sump.
Size: 5" x 2-7/8" x 5/8"
