JE Pistons Honda K20C Ultra Series 86mm Bore 10.0:1 CR Piston - Single

If you're building a high-performance Honda K20C engine, especially one that will see significant boost, you need pistons that can handle the extreme cylinder pressures. JE Pistons' Ultra Series are designed specifically for these demanding applications, offering a robust package that's ready to go right out of the box.

These pistons utilize JE's proprietary Aligned Grain Flow forging technology, which maximizes tensile strength to stand up to the stresses of a power-adder build. They also come with custom-level features like a thermal barrier crown coating to reflect heat back into the combustion chamber, reducing piston crown temperatures and helping with exhaust scavenging. The skirt coating cuts down on friction and wear, keeping things running smoothly and quietly, even on cold starts. Plus, lateral gas ports help maintain a solid seal on the top compression ring, even at high RPMs and under heavy boost.

JE Pistons are made 100% in the USA, and these Ultra Series pistons include strong, thick-wall wrist pins from Trend Performance. This piston is a single unit, and it's important to note that it is not CARB approved, so it cannot be shipped to California.
