Wiseco Professional Series Forged Piston Kit for 1990-1993 Mazda Miata - 78.5mm Bore, -13cc (K554M785)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1990-1993 Mazda Miata (Base, LE, and SE models). Engineered for high-performance and forced induction builds, this Wiseco Professional Series piston kit is designed to handle the increased thermal and mechanical stresses of heavy to severe duty racing.
Forged and machined in the USA from 2618 aluminum alloy, these pistons offer superior tensile strength compared to standard cast or hypereutectic alternatives. Each piston is treated with Wiseco's ArmorGlide skirt coating to minimize friction, reduce operation noise, and provide seizure resistance during extreme conditions. The design features forced pin oiling for consistent wrist pin lubrication and precision-machined crown features for optimized combustion.
