DIY air filter help

[BlackIrish]

Ok so I want to put one of those badass looking forward facing aircharger air filters on a 2003 sportster 1200...wondering if anyone has any info on a cheaper version or how hard it would be to make one. I'm a welder/ metal worker so I can do the brackets and the right angle pipe but is there more to it like sensors and shit??? Anything? Any help? Thanks guys

No sensors on carbs man just support the carb make a mount on the right angle hose clam with a k&n or something of the like you should be good to go man.

3/8" stainless flange was cut out by a friend on a laser, but there are probably other ways to get it done. Stainless elbow from McMaster-Carr for about 12 bucks. K&N filter for about 50 bucks. This one fits the original butterfly Keihin, so I had to make an adapter to run it on the CV.

Thanks for the help guys, I'll post an update once I get to work on this thing

Wait a minute...just realized I don't know what size the pipe has to be??? Anyone know the Outside diameter of the pipe I need for a k&n filter or I guess any filter?

Measure the inlet of your carb. A CV is approximately 2-1/8", so use an elbow with an i.d. closest to that. You want "tubing" not "pipe". Tubing is measured by the o.d., pipe is measured by the i.d. Here's a link to the elbow I used, but the price went up since I built mine.

K&N makes all different sizes of filters, go to their website and search by size & shape.
