JE Pistons Kawasaki ZX12 12.9 to 1 Piston Single

This is a single forged piston from JE Pistons, designed for the Kawasaki ZX12. It features a 12.9 to 1 compression ratio, which is a notable increase over stock, intended for performance builds where higher compression is desired for improved power output.

JE Pistons are well-known for their durable construction and precision manufacturing. This piston is forged from high-strength aluminum alloy, a process that creates a denser, stronger material compared to cast pistons. This makes it more resistant to the stresses and heat generated in a high-performance engine. The 12.9:1 compression ratio is achieved through the piston's dome design, which works in conjunction with your cylinder head to achieve the target ratio. It's important to ensure your engine management system and fuel octane are appropriate for this higher compression level to prevent detonation.

This piston is sold individually, so you'll need to order the correct quantity for your engine. It's not CARB approved and cannot be shipped to California.
