Review SP1 Mn/kep7 T moly Series Piston Kit Polaris Sp Engine Pistons Ml fits INDY 800 2014

Introducing the SP1 MN/KEP7 T-Moly Piston Kit, a high-performance upgrade for the 2014 Polaris 800 Indy SP engine. This piston kit is engineered to deliver increased power, improved durability, and enhanced reliability for your snowmobile.

The pistons in this kit are made of T-Molybdenum material, which is known for its exceptional strength and heat resistance. The T-Moly pistons feature a unique design with a compression height increased by 1.2mm compared to the OEM pistons. This results in a higher compression ratio, allowing for more efficient combustion and ultimately, more power.

Additionally, the piston skirts have been optimized for a better seal against the cylinder wall. This reduces blow-by gases and minimizes piston slap, leading to improved engine efficiency and longevity. The piston rings are also included in this kit, ensuring a proper seal between the piston and the cylinder wall.

The piston pins are made of high-strength billet steel, ensuring maximum durability and resistance to fatigue. The piston pin bushings are made of phosphated bronze, providing a smooth, wear-resistant surface for the piston pin to slide in.

The piston kit also includes new piston pin retainers, which are crucial for maintaining the piston in place. These retainers are made of high-strength steel and are designed to withstand the rigors of snowmobiling.

In summary, the SP1 MN/KEP7 T-Moly Piston Kit is a premium upgrade for the 2014 Polaris 800 Indy SP engine. It offers increased power, improved durability, and enhanced reliability through the use of high-quality T-Molybdenum pistons, optimized piston skirts, high-strength billet steel piston pins, and phosphated bronze piston pin bushings. Upgrade your snowmobile engine today with this top-of-the-line piston kit.
