1.) remove air intake box assembly unbolt the the air box and set aside.
2.) remove passenger fender and passenger headlight. set aside
3.) remove factory rubber air director from factory airbox
4.) trim the factory rubber air director so that it looks more like a coupling for a pipe connection leaving the original connection to the air box the same.
5.) carfully heat the rubber air director so that it will stretch over your 3" abs elbow.
6.) place elbow and rubber pipe connection through the original air hole in your inner fender reconnect the base of the factory air box.
7.) point the elbow on the outside on this inner fender in the general direction you want to run the pipe. (allowing clearance for outter fender) max distance between inner fender and inside of the elbow coupling 1 1/2" on mine).
8.) use a sharpie to place indicator marks showing the direction the elbow is turned relevant to the direction in which the air box sits place a mark on the air box the coupling and the elbow so you can line these up in the future if needed.
9.) take painters tape and tape off area in which you'll be placing another hole for your 2nd elbow to pull air out of the vehicle. clean all the inner fender sufaces so sylicone can seal against the metal surfaces.
10.) theres really only one area you can bore a large enough hole for a 3" elbow (see pictures below) hold your elbow in place against the tape you put up and trace the outside of the elbow
11.) using whatever method of cutting you have avaiable cut the hole out keep in mind your ECU and wiring is right behind the area your cutting so keep your work shallow (theres about 2" from the outside of the inner fender to the face of the ECU) theres rubber and insullation just behind the metal to protect everything from sparks or metal shavings. As well the metal is only 1/16" thick if that maybe an 1/8" in a few places. I used a 1/4" drill bit with a depth gauge and poked serval holes around the inside of the hole I traced then used a drimel tool cut off wheel to complete the cut. dont go all the way to your trace line its helpfull to keep this fit tight to allow for better sealing later.
12.) once your hole fits the elbow inside remove the insulation and rubber pluging the hole place the elbow up there and cut about 20" worth of ABS 3" pipe. stick the cut pipe in one of the elbows and get an idea of where the pipe needs to bend.
13.) using an adjustable heat torch heat the plastic pipe being carefull not to melt it heat the pipe slowly for about 10 minutes if you go slow enough you can create a nice smooth bend and not kink the pipe like i did lol.
14.) once fitted place indicator marks on the pipe and elbows marking there angles to each other.
15.) remove the assembly, fit all your pipes and elbows and rubber connections ensuring the allignment of all your marks.
16.) using sylicone seal all your connections every elbow the rubber connection to your air box everything.
17.) while the sylicone is still flexable assemble your new snorkel. be sure to sylicone around the bolts for the air box as well as any holes in the airbox.
18.) once everything is installed airbox bolted down an pipes in there holes connected use sylicone and create about a 1/2" bead around the hole running into the cab and the hole running into your engine bay. the more sylicone the better!!!
19.) out of preference I used underbody coating (ruberized) to help seal up the sylicone connections plus it kinda looked cool once i got done lol.(yes i know you'll never see it or show anyone lol)
20.) It might not be a must do but i used some copper doorbell wire to help support the assembly to the inner fendor a zip tie would work to just didnt have one.
21.) re-assemble head light and fender to original location using the marks left from the fender bolt washers insure that the washers sit back in the same spot this will put all the body lines back to there original locations.
appologies for any miss spelling or grammer im better with a wrench than a keyboard.
