These are Mahle PowerPak forged 4032 alloy pistons for Honda/Acura B-Series engines. Mahle makes several B-Series Pistons and we try to keep several of the most popular part numbers in stock. Just select which part number best fits your application from the list below, and include that part number in the notes section of your payment.
Mahle Pistons are made of a high silicone 4032 alloy which is designed to have a lower thermal expansion rate than the commonly used 2618. These pistons go through several heat treatments that provide them with a higher strength and wear resistance with an evenly distributed hardness.
Coating-
Mahle PowerPak pistons are Coated with a phosphate dry lubricant to protect the rings against micro-welding and enhance lubrication on the skirt/cylinder area. The Phosphate coating gives the piston its grey appearance provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure. They also feature a Grafal anti-friction coating on the skirts to reduce drag, scuffing, friction, and cylinder bore wear. This also reduces piston noise.
