So this is the tiny little hole that passes for our air intake, (it sits on top of the filter), you can get a K&N hi-flo but that intake is going to be your bottle neck.
Solution, DNA makes a stage 2 large mouth intake that sits atop their filter and does away with that entire contraption for $65, (Nick's gonna yank his hair out), but I'm thinking I could make that intake plate out of a piece of 1/8 inch thick wood myself, same thing.
After installing a DNA pod filter, stage 2 intake plate and a $400 Dynojet power commander... (this is not my bike)
The dyno charts show stock in red, after mods in blue, (this bike also has a roughly $800 Arrow exhaust), doesn't look impressive, gained a little mid range at the cost of about $1350 plus install time and expense. Top chart is hp, bottom is torque.
For only an extra thousand dollars you could have bought an FZ-09 and had about an extra 45 hp and 11 lbs. more torque, these mods aren't worth it in my opinion.
