I'm doing a stage one with supertrapp 2-1's, i am getting a high flow replacement for my stock air cleaner.

Which after market cleaner should I go with? The kuryakyn mach 2 co-axil, the new one just released, screaming eagle, v&H, roman sands?

Is there a big difference in the performance between all of these?

 

All of those are going to flow more air than your motor can use. I went with the Screamin Eagle Round Stage 1 AC on my bike. Get what you prefer looks wise and you should be fine.

 

Figure Machine has a wide variety of styles and sizes. You pick the design and color. Made in the USA with USA materials, well engineered and top notch customer service. They have other parts, too, that can be matched to your air cleaner. Definetly worth a click.

I have a figuremachine.com air cleaner and it is really nice high quality and reasonably priced. Def check them out and see their designs.

 

I'm happy with my Vance & Hines VO2 Naked air filter.

Comes with a washable H&N filter. At a reasonable price compared to a lot of others and lets you choose whether you put a bell type cover over it or just run it Naked with an end cap cover over the end of it.

 

All of them are going to allow more air into the intake and are considered a Stage 1 upgrade, what it actually comes down to is looks, depending on what style you perfer.

 

Been happy with the VO2 here as well.
