I'm looking at the pictorial for changing out the air filter on our Silverwing and I cannot help but notice the strangeness of the location for this air intake in the first place. From the appearances it is hard to tell where the air is being pulled from. It also appears that the box is very restrictive no matter which filter element you should choose. I should have the new K&N filter by tomorrow when I get off of work and I plan to swap out the stock filter immediately. My bike has just hit 26,000 miles and it is a 2004 so it will be interesting to see if the filter is stock or has been changed out previously. The most important thing I would like to do is make certain that I provide a better source of air to the inlet from a source that is not affected by engine heat in any way. I put cold air intake systems on every vehicle that I own due to the fact that I live in Arizona. I have always noticed that Hondas are very touchy when it comes to high intake air temperature so anything that can be done to reduce the air temperature. I have read where folks have drilled some extra holes to improve air flow but I am wondering ahead of this job if there might be a way to plumb or modify an outside air source to direct ambient air into the intake assembly a little better. Ideally the creation of a lengthened intake tube with conical shaped filter in a strategically placed located would be best but this seems nearly impossible given the stock location of the existing filter box and intake tube.

Has there been anyone out there to develop anything to improve upon Honda's design or is this even possible given the way this scooter is pieced together?

I'm going into this particular modification with an appetite for improvement so if I can see anything before I get any comments back I will look at working out an improvement on my own or with the help of some local fabrication shops here in the Phoenix/North Scottsdale area.

Thank you,

My take...pretty hard to outthink Honda. Filter is hard to get at. But it works.

K & N Filter ok as it is re-useable, when properly cleaned and not over oiled. I would first check on price stock vs K&N.

I'm very interested in the results of your plumbing expedition. Take pics if you can.

Just a little note to note... I believe there is an extra bolt/screw that will be left over if you go to the K&N. Not sure why. But that is the best recollection I have.

Be careful with a self made conical inlet.

When pointing to the front , there can be a overpressure.
When to the rear maybe a vacuum.

I can't tell , the fuel regulator system can deal with that.
