This Performance Kit is a step up from our standard Fix Kit.  If you want the dependability and proven track record MTNTK Performance has with a little more power, then this kit is for you. This kit produces a 5HP gain over stock with increased throttle response from the addition of our billet head domes.  The all new MTNTK Performance Cheater Head with our billet domes is a must have for any snowmobile enthusiast looking to gain more horsepower and better throttle response without any fueling changes or additional engine modifications. Each head is machined to proper specs which results in perfect fitment. Domes are available in 13 to 1 compression ratio for compatibility with pump gas at all altitudes or 15 to 1 compression ratio for those who crave even more on higher octane fuel.   Our performance kit is available for all '08-20 800 CFI Engines. Price includes the refundable core charge and when you order you will receive a machined head.  You can return your head (even if it has damage) for a $75.00 credit.  Order today! Some applications may require heavier clutch weights.
