Wiseco Forged Pistons Mazda MX-5 NA NB 1.8

Wiseco Pistons are synonymous with uncompromising quality. These high-performance pistons are designed for durability and optimal performance. With a Teflon-coated piston skirt, they reduce friction and wear in the cylinder. The precisely machined piston grooves, combined with well-thought-out oil passages and an improved piston crown design, ensure more efficient combustion in the cylinder and minimize detonation-sensitive hotspots.

What truly makes these pistons unique is Wiseco's innovative Armor Plating. This high-performance coating is applied to the piston crown, piston grooves, and the wrist pin bore. This protective layer guards against damage caused by detonation and actually hardens further over time due to the heat of combustion. This coating not only helps prevent micro-welding of the piston ring but also improves piston groove wear and ring sealing capabilities. Inside the wrist pin bore, the coating reduces wear, minimizes friction, and prevents deformation of the circlip groove.

Each set of Wiseco pistons comes with matching piston rings and wrist pins, ensuring you get the best match for your engine.
