Remove the drainage "rubbers" or cut a hole in the mounting plate for the drainage "rubbers" on the intake, that plate supports the air box.....Do you have a picture of YOUR fenderwell not cutout?


Here are two pics I just took. One showing where a piece of foil looking insulation was and what was behind it

What did you use to cut it out?

Harbor Fraught body saw, wished I would have spent a $100.00 on one as they sure use/waste a lot of air. My 17cfm compressor has no problems keeping up with my IR 1/2 impact, DA sander. That thing is horrible but did the job barely....

Cover the motor fender liner to liner, firewall to grill with a paint drop cloth you'll be glad you did....

Is it working correctly?. Take it out and plug the hole. The intake I have does not use the factory filter minder.

It has to be working correctly from what I guess. When I had the stock LLY airbox on, the filter minder never moved, at least that I noticed. Also people have said that the lbz intake really woke up their truck, I haven't noticed much difference on a race tune
