JE Pistons MAZDA 1.8L BP KIT Set of 4 Pistons

This JE Pistons kit gets you a complete set of four forged pistons, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings. These are specifically made for the 1.8L BP engine found in your 1994-1997 and 1999-2005 Mazda Miata. If you're looking to rebuild or significantly upgrade your engine, a solid set of pistons is where you start. These pistons are forged in the USA from 2618 aluminum, a material known for its strong tensile strength, which is exactly what you need when you're pushing your engine hard.

JE Pistons has been making performance pistons for a long time, and they've put that experience into this kit. They use a proprietary Forged Side Relief (FSR) design that helps reduce friction and save weight by using a narrower skirt and a shorter wrist pin. Depending on your specific application, you might also get an accumulator groove to help manage combustion gas pressure, which means better ring seal and more consistent power. Some applications also include a skirt coating to further cut down on friction and noise, while also reducing wear on the piston skirts and cylinder walls. These are designed specifically for your Miata's engine to give you the best combination of durability and performance.

This kit is designed as a direct replacement for your stock pistons, but with a significant upgrade in strength and performance potential. Remember that 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.
