6.5L Performance Piston Kit

These start off as STD bore Mahle 6.5L pistons and are modified in a few key areas to address weak points in the stock design. Benefits: Improve durability of the piston with modern heat reflective coatings The goal here is to prevent hot spots and associated piston crown cracking The IDI combustion process has inherent heat control issues, especially when increasing power output via more fuel over stock and holding elevated EGT levels for extended periods of time Reduce side loading of the piston by improving the flame travel pattern across the crown. Combustion in an IDI diesel happens in the pre combustion chamber and the flame exits the pre-chamber, into the Ricardo Bowl (piston crown), from the lower edge, toward the center of the piston. Add valve clearance Reduce cylinder wear with skirt coatings Power Output: Overall power output is still determined by how much fuel you have. These pistons alone will not add noticeable power. Rather, they support your journey of modi
