I have 2 photos of the installation. Some breather pipes were not connected yet.
I use Donaldson type aircleaners because dirt is not welcome in any engine. Never. Performance might suffer but the engine will last.
This is on the gq with the transplant tb45e engine.
I used the thumbsuck selection method and used a 90mm outlet standard Donaldson cyclone air cleaner. It just fits in under the bonnet and I custom built the bracket for mounting onto the wheel well. The only drawback is that I have to loosen the mount clamps to get to the cartridge for cleaning.
The positioning made for minimal bends and virtually straight pipes in and out. The air gets sucked in from the original hole in the fender , so water does not easily gets in there. Also , the big inlet pipe is at an angle and with low engine speed , water will most likely not get drawn in. On this type , all the air is drawn in at the inlet pipe , so snorkel will work.
The change in pipe configuration played havoc with the engine management. I used the same air mass sensor housing and sensor , but the air flow patterns made no sense to the sensor.
Two hours of remapping by Maus and all was well again.
Those filters are used by most big engines. Look at the big generator sets and air compressors as well as most industrial earthmoving machines.
