I have installed the big filter my way. I removed all parts in front of the 90 degree elbow attached to the turbo , I mean everything , gives you some room. Next buy a 4inch abs black plastic coupling , drill a hole same dia as the inlet sensor, install the sensor. place coupling in elbow from turbo tighten the clamp. I put two rev. of friction tape on the big wix filter and let it rest on the coupling, now go go go no restiance. https://www.turbodieselregister.com/forums/newthread.php?do=newthread&f=14#
