Among the many unique technological advances CP Pistons uses to ensure our customer’s performance edge, Maximum Internal Lightening (MIL) has quickly become one of the most effective. Although CP Pistons has one of the largest ranges of forgings available in the industry, there are still times when a customer’s requirements may result in a piston that is not an ideal match to the forging used. As a result, some areas may be thicker than the specific application may require. As we all know, more weight means a slower acceleration curve and more strain on the other internal components. Our MIL process allows us to remove that unnecessary material, freeing up that horsepower and reducing the load on the other components in your engine.

MIL is CP Pistons’ proprietary technology that creates a very lightweight piston, cutting away the excess material along the inside of a piston to match the contour of the external features. Our engineers use their knowledge of piston design, our in-house computer modeling software which can utilize FEA, and the performance needs of each individual customer to decide precisely how much inner material can be removed without decreasing reliability. Each internal profile design is perfected then machined on four and five axis CNC mills.
