    I'm lost. I'm not sure if I'm just missing something or if I'm just missing something. Purchased a K&N slightly used, tried installing today and have two major road blocks.

    Instructions here: http://www.knfilters.com/instructions/57-9015-1_inst.pdf

    1. I have an '02, and I have a crank case vent resonator chamber. I just don't see what grommet fits onto the tube to accept the chamber ... I just don't see how this fits onto the tubing.

    2. I installed the new intake tube, but the other issue I'm having is the tubing is not long enough (neither the one provided or the one coming from the engine. In picture 20 on instructions, its the line on top (closest to engine). This could be an easy fix because I have the same tubing in the kit that comes from the engine but I just need a hose fitting to connect them. But it sure seems like I'm missing something there, right?

    My 2 is a big problem, but I'm completely lost on the crank case vent chamber deal. Anyone run into this issue or have any suggestions?

    I've spent twice as long on this as I ever expected.

    That's what I've tried. I got so frustrated I had to. I just don't see how the chamber attached to the tube. You're supposed to drill a hole into the intake tube (I assume that's because the hole isn't always open in instances where there's no chamber to worry about). Mine was already drilled because I believe the previous owner needed it too. What I don't get is how the chamber attached to that fitting. The fitting is very small, and it appears there's a grommet to help it fit. I just don't see it.

    The one thing I have figured out is that I can avoid using the crankcase chamber entirely and connect one of the two accompanying hoses directly into the the third hose at the top of the compartment - I'm actually not sure what that hose is but it's what the crank case chamber ran into before.

    Is the crank case chamber piece necessary?

    I guess that goes directly to the crankcase vent.

    I have a big rubber grommet, yes, and it fits snugly on one side of the chamber (the larger side). The problem is vent on the intake tube is really small, and the grommet doesn't come close to making the chamber fit on it.

    To my last post ... on 8c of the instructions, I have no piece that connects to that outlet. If you look at 10 on the instructions, you see the small tube at the top ride side of the picture. Then look at 21a, where the chamber is then connected. The grommet I have does fit on the large end of the chamber, but it doesn't fit it to the small outlet shown on 10 or 8b.

    i remember that step... it was a bitch getting the chamber into the grommet...

    if you have a heat gun or a blow dryer, heat up the grommet enough to wiggle the chamber into it...

    I have the chamber in the grommet - the problem is the end of the grommet doesn't attach to the outlet on the tube ... the chamber end (with grommet) is like 1-inch diamter, and the tube is tiny like 1/8 or 1/4. They just don't match up at all. It's where I'm stuck 'cause nothing fits. That make sense?

    yah, we had the same problem... had to wiggle it in and use a pick along the OD at the same time... its a pain in the arse to get that piece into the tube too...

    I'll try to throw a picture up before I leave. Not sure if I'm explaining it right, but there's nothing the crank case chamber piece will fit into ... it's not a matter of fitting, it's a matter of the pieces that fit on it are too big to fit onto the intake outlet.

    How crucial is that crankcase chamber? Obviously it's a tiny air reservoir, so I imagine it changed airflow to some extent. I can bypass it, but I worry that it would screw something up? Anyone know?

    I might have figured it out. I think I need to drill out a larger hole into that intake tubing ... Being that the pieces weren't exactly new, I assumed the previous owner drilled out the 5/8" tube (I thought that tube was closed and he drilled it out to allow air to flow through). I believe I need to drill a full 1 3/8" hole into the site of the tube and that will allow the giant grommet to fit properly. Mike, do you remember having to drill a hole that larger that basically took out the pre-existing tubing that was originally on the intake tube?

    Hey guys, thanks again for the help. Seems to be running fine.
