509 Sinister Goggles
14 Super Flow Vents - 509 engineered 14 vents
across the top, sides, bottom, and lens which create a continual flow
of cool comfortable air, thus exhausting all the hot air out the bottom
of the goggle. This provides a controlled climate inside the goggle,
keeping you comfortable and fog free.
Boyesen Power Pack
If you're performance minded (faster, farther, more efficient), then
the Power Pack system from Boyesen is for you. The company reports that
the system will optimize airflow and fuel delivery, eliminate off-idle
hesitation and provide your sled with increased horsepower and torque
through the entire rpm range. Through Boyesen's research, the best
features of the company's Rage Cage are coupled with the performance
that the Boyesen Power Wing and reed systems offer. It's a cast
aluminum system. Currently the Power Pack is available for '04-08
Ski-Doo SDIs and '05-07 Ski-Doo Mach Zs, but the company is likely to
expand to the other Big 4 soon.
XP Hot Air Elimination
Kits
SLP Hot Air
Elimination Kits help reduce stagnant underhood hot air to maintain
higher horsepower by delivering additional cold air intake and hot air
escape from the chassis. This kit includes one shock tower air
inlet vent, an upper side panel air vent, and one outlet vent.
Each vent utilizes a powder snow pre-filter that repels snow and water,
yet allows air to pass right through.
Accurate machine. High
quality steel billet is hardened and tempered to our specification.
