mountune’s extensive knowledge of the Ford EcoBoost
engine coupled with broad motorsport experience provides the foundation for the
ultimate 2.0L Ford EcoBoost forged piston. Engineered in house by our
motorsport division and manufactured exclusively by our partner Mahle
Motorsports, the mountune forged piston set for the 2.0L Ford EcoBoost is a
fully featured piston with many of the same upgrades we use in our professional
Produced from modern 4032 lightweight alloy forgings
for maximum oil control and quiet operation, each piston features supported pin
bosses to withstand the extreme conditions found in engines operating with high
cylinder pressures. The layout of the piston has also been optimized with
weight reduction in mind and reduced skirt profiles to minimize friction. Mountune
pistons also include gas accumulator grooves developed during extensive testing
and tailored for the EcoBoost engine. Careful consideration has been used in
the “bowl” area of the piston to maintain Ford’s original profile to ensure
proper and efficient combustion.
Tool steel 22mm internally tapered, short wrist pins
are used to reduce pin flex and weight. Mountune connecting rods are
recommended to ensure a matched set of components.
As an added feature, 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.
Hard anodized top ring grooves have been incorporated
for increased durability and strength to withstand the high cylinder pressures
of high boost engines.
- 1.2mm gas nitrided top ring:
Superior combustion sealing, strength
and wear compared to traditional 1.0mm steel top rings.
- 1.2mm gas nitrided second
ring: Superior strength and wear compared to traditional iron second rings.
- 2.0mm soft nitrided oil rings:
Superior strength and sealing properties
compared to traditional 2.8mm rings
Available in 9.0:1
compression ratio for high power applications or standard compression ratio of
9.3:1. These pistons are not compatible with the original Ford connecting rod.
We recommend genuine mountune forged connecting rods for maximum reliability.
