Part # MMCENG1020ST
We have taken our knowledge and experience with 4G63 motors and applied it to the 4B11 platform. It’s time to make some serious power with your Mitsubishi Evolution X or Ralliart.
Magnus 4B11 pistons are more than your standard replacement pistons for the 4B11. All pistons are for turbo and nitrous applications, unless specified for naturally aspirated use. We designed these heavy-duty pistons for maximum horsepower, perform under extreme heat and boost pressure while being the lightest weight possible and retaining high strength. The latest technology in the “ring pack” features low tension and low drag rings with superior sealing properties. All of this equates to the most engineered piston on the market. Compression ratio 9:1 with factory head gasket. Custom compression ratio and bore size available upon request.
- Extra thick piston crown to create a larger heat dissipation surface for higher horsepower capability and extreme temperatures.
- Specially designed Magnus “Quench Pad Dish” improves power and reduces the chance of detonation.
- Using Magnus’ own “Silent Bore Technology” keeps the piston silent in the bores when running recommended large clearances.
- Extra large valve reliefs to accommodate large valve and camshaft upgrades.
- CAD Designed in house using Magnus’ proprietary piston technology.
- Add ceramic coating to the crown surface of the piston for the ultimate protection against heat and detonation.
