Wiseco Forged piston kit 4B11 88mm Bore
The Mitsubishi EVO 10 is proving itself to be worthy to the name. The 4B11 is quickly being developed to reach power levels of its predecessor- the mighty 4G63. Wiseco has built the strongest piston available with features like .300 top land thickness and .335 of 2618 alloy below the dish. .200 wall pins are standard and Armor Glide skirt coating allows for tight piston to wall clearances for reduced noise.
