From Drag to Endurance CP pistons have proven their quality in the racing community. These pistons for the 2008-2013 Evo X are avialable in 86mm stock bore, 86.5mm w/ 0.5 overbore, or 87.0mm w/ 1.0mm overbore and retain a 9.0 compression ratio. These pistons are designed for high horsepower applications and are much stronger then OEM due to the forging process CP uses. The CP pistons for the Evo X 4B11 are an excellent choice for your engine build.
CP offers optional coatings to enhance the effectiveness of your pistons. The top coating is designed to reflect heat into the combustion chamber, thereby increasing exhaust gas velocity and greatly improving scavenging potential. The skirt coating offers additional lubricant in times of extreme heat or heavy wear situations. The coating is designed to reduce friction on the skirt by providing a buffer to the cylinder. Coating options are applied to the entire set and add 4-6 weeks to the order time.
