Description

The Supertech P4-MA8350-N4 pistons are engineered for enhanced performance and reliability in high-demand applications, specifically for Mazda Miata 1.8L BP DOHC engines. These forged pistons measure 83.5mm in bore diameter and have a -4cc dish volume, resulting in a compression ratio of 8.6:1. Constructed from a durable 4032 alloy, they are designed to withstand the rigors of turbo and nitrous builds. This set includes four pistons, but notably excludes rings, which must be sourced separately. The specifications indicate an oversize of +0.5mm and a head cc of 50, making them a suitable upgrade for enthusiasts seeking to increase their engine's power output and durability. They are ideal for complete street performance applications. These pistons are specifically designed for the 1994–2005 Mazda Miata 1.8L BP DOHC engine. Ensure compatibility with your specific engine build, especially if considering forced induction.
