nytro air box mod

[Dirt Digger]

Anyone adding intakes to the stock airbox on a nytro. I just have an excell pipe and muffler. Would an airbox mod help or mess things up with the stock computer.

Ulmer racing did a bunch of dyno testing, with air box mods. No gains were found, and some cases the motor even lost a bit of power. Only intake mod gains to be found, was switching out the air box for K-N filters. They are good for a couple of hp gain through out the power band I believe.
