Wiseco MAZDA MIATA 1.8L 4v 10.5:1 83.5MM Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your 1994-2005 Mazda Miata 1.8L engine. The 83.50 mm bore size and 10.5:1 compression ratio are designed to handle the demands of heavy or severe duty builds, whether you're pushing the limits on the track or building a high-performance street machine.

Wiseco machines these pistons in the USA, focusing on details that matter for durability and power. You'll find precision ring grooves, anti-detonation features, and enhanced ring seal designs to ensure optimal combustion and longevity. The crown is fully machined for a clean, consistent surface, and forced pin oiling helps keep the wrist pin lubricated under extreme conditions. Plus, the ArmorGlide skirt coating reduces friction and noise while resisting seizure, making for a smoother, more reliable operation.

This set includes four pistons, ready to be installed in your 1.8L 16V L8 engine. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
