Now there’s a way to ensure more reliable power from EcoBoost-powered 2.3-liter engines with the introduction of MAHLE Motorsport’s 4032 alloy Ford EcoBoost 2.3L PowerPak Plus Piston kit.
Designed for heavy-duty applications in which the OE cast piston has been known to fail, MAHLE Motorsport has introduced a 4032 alloy option that not only adds much-needed strength, but also allows for a tighter piston to wall clearance for quieter cold startup, according to the company.
MAHLE Motorsport’s 2.3L PowerPak kit is loaded with value-added features for reliable power production for any 2.3-liter EcoBoost engine, according to MAHLE.
To help correct problems associated with the OE cast piston, MAHLE Motorsport manufactured this kit with a thick slipper-skirt-style forging and an enhanced OE crown design with increased radius for improved strength. Other special features include a heavy-duty 0.200-inch wall thickness; H13 tool steel wrist pins; and a hard anodized top ring groove that is ideal for extreme-duty applications.
The pistons are engineered with thick 0.235-inch top and 0.200-inch second ring lands. The pistons are designed for OE 149.3-millimeter-length connecting rods and OE 22.5-millimeter wrist pins and an OE 32.8-millimeter compression height. Valve pockets and depth accommodates both the 2-liter and 2.3-liter OE EcoBoost heads with a 9.5:1 compression ratio.
The new PowerPak Plus kit is available in 87.51-millimeter (No. 197937145) and 88-millimeter (No. 197937165) bore sizes and includes a nitrided steel 1.2-millimeter top, 1.2-millimeter second, 2.8-millimeter oil-ring set. The pistons are coated with MAHLE’s unique GRAFAL anti-friction skirt coating and phosphate to prevent microwelding and pin galling.
