CP Piston & Ring Set for Mitsubishi 4B11 - Bore 86mm - Size Standard - Comp Ratio 10.0 - Single

If you're rebuilding the engine in your Mitsubishi 4B11, a solid set of pistons is crucial for performance and reliability. This set from CP Pistons is built for that job, offering a standard bore size of 86mm and a 10.0:1 compression ratio. This compression ratio is a good balance for many performance builds, allowing for increased power without requiring exotic fuel in most setups.

CP Pistons are well-known for their forged construction, which means these pistons are incredibly strong and can handle the higher stresses of a performance engine. Forging the aluminum creates a denser, more durable material compared to cast pistons, making them a popular choice when you need parts that can take a beating. This set includes the pistons and rings, so you have the core components ready for installation.

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.
