Overall, the AEV snorkel is a nice package although my primary complains are directed at these two areas:
AEV bumper - this piece interferes with the OEM front lower trim piece and should not. Being required to spend an hour wrestling with a 1/4-ton bumper and winch combo should not be required when removing a two pound plastic trim piece that normally takes five minutes to remove.
AEV snorkel - the airbox is a combination of metal and plastic which itself is not good. TO make matters worse, they expect the installer to place the disassembled airbox into where it will reside and perform final assembly which includes maybe a dozen rivets. The rivet hat should penetrate first through the plastic while the stem goes through the metal - this is the strongest method of assembly since it is easy for the plastic to deform while the stem is pulled through. Around half of the joints are correct whereas the other half are not so this leads to failed joints. It would have been better to develop a single piece box or maybe one with an angled horn that passes through one of the walls with metal rings on the outside of each. In summary, the piece is unnecessarily complex and much time is wasted on an inherently weak component.
As previously mentioned above, some have complained about how the snorkel attaches to the a-pillar. If installed properly I do not expect to have problems with this although if I do I will be happy to share. I came upon this video titled
"How to fix the weakest part on the AEV snorkel - upgrade the mounting hardware." Here are sections that raised questions in my mind:
0:26-0:36 - Installer only has one 1/2" rubber expansion well nut installed while the instructions specify two. The single 1/2" rubber expansion well nut is installed backwards (the shoulder should be up top with the brass threaded insert on the bottom) so when you tighten the screw the brass insert compressed the rubber above and it expands. In his defense, the AEV instructions do not specify how to properly install a rubber expansion well nut.
2:30-2:40 - Installer confirms that he ignored AEV instructions and only installed one rubber expansion well nut.
4:30-5:40 - Installer set in place two Nutserts into curved surface of unknown thickness. At first I was concerned of using a Nutsert on a curved surface since I have only used on flat ones - I was wrong and they can be used on curved surfaces. What I am not sure about is how thick the surface is since Nutsert specifies a minimum surface thickness of 0.030" which is awfully close to the thickness of the a-pillar. I would have measured it first and talked with the manufacturer if I had any additional questions.
I do like how he was innovative and did not remove the entire fender just to deal with this issue - he simply loosened most every thing up and pulled the snorkel out of the way to perform that work. I also like how he applied a waterproof sealer to the Nutserts, bolts, and washers. The AEV instructions do not specify this although I did the same since I would not want water to leak into the a-pillar.
Others have suggested using
3M VHB Tape which sounds like it too might be a successful application although I would contact a 3M technical representative to discuss which tape would work best and how to properly prepare the surfaces.
