Mahle Piston Set 2.3L Ford EcoBoost / Focus RS
The Mahle piston set for the 2.3L Ford EcoBoost or Focus RS is crafted from modern 2618 lightweight alloy forgings for extreme duty and reduced skirt profiles to minimize friction.
Each piston features supported pin bosses to withstand the extreme conditions found in engines operating with high cylinder pressures. The 22.5mm internally tapered, short wrist pins are used to reduce pin flex and weight.
The gas accumulator grooves were developed during extensive testing from Mahle and tailored for the EcoBoost engine. Hard anodized top ring grooves have been incorporated for increased durability and strength to withstand high cylinder pressures for high boost engines.
Mahle's phosphate dry lubricant coating is used on the entire piston to reduce micro-welding and pin galling. Additionally, Mahle's Grafal skirt coating is used on the piston skirt to reduce cylinder wall friction reduction.
