JE Pistons MINI COOPER S 8.3:1 Set of 4 Pistons

If you're rebuilding the engine in your Mini Cooper S, especially if you're aiming for more power or durability, a strong set of forged pistons is a critical component. These JE Pistons are built specifically for the 1.6L SC Tritec engine, offering an 8.3:1 compression ratio that's well-suited for boosted applications where you need to manage detonation. They are forged and machined entirely in the USA, using 2618 aluminum, which provides the high tensile strength needed for demanding performance builds.

JE Pistons brings over 75 years of experience to these components. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, saving a bit of weight in the process. Depending on the specific application, you might also find an accumulator groove to help control combustion gas pressure and improve ring seal, along with a skirt coating to further reduce friction and noise. This kit includes everything you need to get started: the four pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings.

When you're putting together a performance engine, using parts designed for the specific application makes a big difference. These pistons are tailored for your Mini Cooper S engine, ensuring optimized performance and durability. Remember, these are not approved for sale in California due to emissions regulations.
