Espar AM3-D4R 12V Airtronic Replacement Heater (Heater & FMP Only)

Espar / Eberspaecher AM3-D4R 12V Airtronic Gen 3 Replacement Heater — Heater & Fuel Metering Pump

The Airtronic D4R is Eberspaecher's 3rd generation high-output diesel air heater, delivering reliable cabin heat in demanding vehicle and marine environments. With a higher air throughput than the D4L — 190 kg/hr vs. 185 kg/hr at maximum output — the D4R is the preferred choice for installations requiring maximum heat delivery from a compact unit.

Note:  Air throughput specifications were determined using a 75mm heater hood, the AM3-D4 heater kits come standard with 90mm ducting and a 90mm heater hood.

This listing includes the replacement heater and fuel metering pump (FMP) only. No additional installation hardware or wiring harness is included.
