Been awhile since I visited this thread. That was due to the fact that I had never had a chance to plumb the entire system. Yes, I was running the snorkel just mounted to the body and only that.
The K&N filer was just running like a CAI and just that.
I was finally able to get Hellhawk into the garage and work on the snorkel tonight. About another 3-5 hours but the install is complete. Here is the final documentation of what transpired:
1. Use of the K&N heat shield cannot be used. It located the filter too far forward to allow a smooth turn of the piping to access the snorkel.
2. The K&N silver pipe had to be modified by a cutting wheel. The forward most portion had to be trimmed back 1" to allow the needed room to give the Apollo intake the space for the piping to turn towards the snorkel.
3. The piping of the Apollo to the K&N silver pipe is actually a hair smaller. But the intake plenum that comes with the CAI can be utilized to work with the Apollo. What I did was center the intake plenum on the back of the Apollo, and used 1/8" foam tape to mount it to the backside of the Apollo. From there I used 8 self tapping screws to hard mount the plenum to the backside of the Apollo. This ensured a water tight seal that could not be broken. The plenum was then notched out for the oil recirculating pipe and slide right over the K&N silver tube nice and tight. I used one 8mm x 3/8 self tapping screw to hard mount the Apollo to the K& N silver tube.
4. I then removed the factory U pipe for the stock air breathing system. I did this with the bumper on and by just peeling away the inner fender liner to access the one bolt that hold it to the body. There is a pressure spherical bolt that mounts to a rubber stay that pulls away from the body as well. I pulled this away and tossed the factory piece.
5. From here I ran the included flex tube from the Apollo down from the intake and back up into the fender liner area. It sits just above the fender liner nice and tight. I used the 4" - 3" reducing 90 degree elbow to mount the flex tube to the snorkel. 1" of the elbow needs to be removed from the 4" side.
6. I ensured all the connections were tight and started up the engine. No codes no lights all was perfect.
Results: The K&N CAI was great. Nice rumble, and allowed the engine to roar when you got on the throttle. Now that that sound has been moved from inside the engine bay to the exterior via the snorkel, it is about 100 percent louder and has a bit of a more grumble to the tone. Most likely because the resonance is amplified through the snorkel itself.
Here are the remaining pictures that will document the install.
Note that the 3" intercooler piping kit is not needed at all. Just the snorkel, MFC designed foam mount, K&N Apollo intake and K&N CAI is all that is needed. Any questions please ask. More detailed picture will surface, once I get a chance to clean it up in there and show you in better light.
