CP Piston & Ring Set for Mazda DISI MZR 2.3L - Bore 87.5mm - Size Standard - CR 8.5 - Single

This is a single forged piston and ring set from CP Pistons, designed for the Mazda DISI MZR 2.3L engine. You get one piston, a set of rings to match, and the necessary wrist pin to connect them. This set is built to standard bore size, 87.5mm, with a compression ratio of 8.5:1, making it a solid choice for rebuilding or upgrading your engine.

CP Pistons are well-known for their robust construction, and this forged piston is no exception. Forging the aluminum creates a stronger, more durable piston compared to cast alternatives, which can better handle the increased pressures and heat found in performance or heavily used engines. The 8.5:1 compression ratio is a good balance, offering a slight improvement in power over stock without being overly sensitive to fuel quality, though it's always best to use the recommended octane for your specific application.

Keep in mind that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
