Review on Beler Eberspacher Airtronic Heater 252069011300 Replacement Parts by Chad Judex

Product does not work with Espar D2 heater. The threads seemed to be loosening and the hex head design is a little different from Espar's filament design which doesn't seal well and allows air into the combustion chamber. This disrupts the air-fuel mixture and the heater will not ignite. The heater will not work with these filament pens. Once the thread and hex head issues are fixed, everything will likely work fine. This is currently not the case. I returned the part.
