This is the genuine Bosch 0432191290, a new mechanical fuel injector for the Mack E7 ASET engine. It is a complete nozzle and holder assembly, set and ready to fit. It replaces Mack 736GB419M2 and 25101204, the Mack exchange number 736GB419M2X and PAI 891965. Opening pressure is 240 to 260 bar.

Mack used several Bosch injectors on the E7 family, and each has its own Mack number. Bosch lists Mack 736GB410M and 736GB420M under the 0432191283, and Mack 736GB410M3 and 736GB420M3 under the 0432191284. Order by the Mack number in your parts book or the Bosch number stamped on the old injector body, not by the engine name alone. The engine takes six.
