So nobody really makes a CAI for our beloved VXs so I'm going to make my own.

My thought is to remove the stock intake box.
Use a K&N RX 4120 that actually will fit inside the cold air duct in the front fender. It has the filter in the nose as well for maximum air flow. I believe this will be better than a filter that has a solid end. The collector at the fender is 4 3/4" wide and has a depth of about 3".
Have my local muffler shop bend me a tube that will connect the MAF to the new filter placement using 3" stainless pipe.
Use the OEM black tube from the throttle body to the current MAF location.

My biggest question is where does the MAF really need to be in this process? I would like to leave it where it is and connect it to the new pipe, but I could relocate it to the filter end, near the front fender if that's better for some reason.

The other two options for a filter are both K&N; one is the RX 3990-1 (which is really a big filter) and the RX 4140 that's smaller, but also requires a 3 1/2" pipe. The MAF connector is a 3".

Just looking for some feedback.

Thanks.
