Mahle 930258362 PowerPak Plus Pistons Ford 5.0L Coyote Gen 3 3.662in 12:1 Set/8

Vehicle Fitment

• 2018-2023 Ford Mustang GT (5.0L Coyote Gen 3, DOHC V8, Direct Injection + Port Injection, 460 hp)

• 2018-2023 Ford F-150 (5.0L Coyote Gen 3 Truck Tune, all trims equipped with the 5.0L V8 option)

Fitment Notes

• Designed specifically for the Gen 3 Ford 5.0L Coyote (2018+) with dual-injection (direct + port fuel injection) - NOT compatible with Gen 1 (2011-2014) or Gen 2 (2015-2017) Coyote engines, which use a smaller 92.2mm (3.630 in.) bore
• Does NOT fit the 2024+ Ford Mustang GT Gen 4 Coyote - verify piston compatibility with the Gen 4 engine before ordering for 2024 and newer applications
• Drop-in forged replacement assembly - designed for standard Gen 3 bore of 3.662 in. (93.0mm); installs into the unmachined Gen 3 block without boring required if cylinders are within standard bore spec
• Piston-to-wall clearance must be verified with your machinist using actual measured bore diameters - do not assume standard bore without measurement
• Ring set is file-fit - ring end gaps must be set by your engine builder prior to installation
• Compression ratio of 12.0:1 matches the factory Gen 3 Coyote specification; confirm piston-to-valve clearance and head gasket stack with your builder if used with non-stock heads or camshafts
• Not CARB legal - not for sale or use in California
• Sold as a complete set of 8 with rings, pins, and locks
• Professional engine builder installation required

Features

• Mahle MS PowerPak Plus Series - Mahle Motorsport's flagship forged performance piston line, incorporating over 95 years of piston manufacturing expertise from OEM to Formula 1 racing applications
• Forged from 2618 low-expansion aluminum alloy - provides maximum high-temperature strength, fatigue resistance, and ring land durability under boosted and high-RPM conditions
• Positive dome design (8.4cc) achieves the factory Gen 3 Coyote 12.0:1 compression ratio, maintaining OEM power characteristics and knock thresholds while enabling a forged drop-in build
• Drop-in design for the 2018+ Gen 3 Coyote 3.662 in. bore - eliminates the need for block machining on standard-bore engines, reducing build cost and complexity
• Mahle Grafal proprietary anti-friction skirt coating reduces friction, scuffing, and cylinder bore wear while reducing piston noise - the same coating technology used in Mahle OEM piston programs
• Phosphate coating applied to ring grooves and wrist pin bores protects against ring micro-welding and pin galling during initial startup and break-in
• Forced wrist pin oiler lubrication channels provide continuous oil delivery to the wrist pin interface for extended pin and bushing life under sustained high-RPM operation
• CNC precision-machined wrist pin bores ensure exact compression distance and precise pin fit across all eight pistons
• Slipper skirt forging design reduces weight versus traditional full round forgings while maintaining structural strength - lightweight at 373 grams per piston
• Hand-deburred finish eliminates stress risers and sharp edges that can initiate fatigue cracks in high-cycle applications
• Performance 1.0mm / 1.0mm / 2.0mm file-fit ring pack provides reduced ring tension for lower friction and improved sealing over OEM-width ring sets
• High-quality steel wrist pin (0.866 in. / 22mm, 112 grams) paired with race-proven round wire locks included in the kit

Product Description

The Mahle 930258362 is a complete set of eight MS PowerPak Plus forged pistons with rings, pins, and locks for the Ford 5.0L Coyote Gen 3 engine (2018-2023) found in the Mustang GT, Mustang Bullitt, Mustang Mach 1, and F-150 with the 5.0L V8 option. Designed as a drop-in forged replacement for the Gen 3's standard 3.662-inch (93.0mm) bore - increased from the Gen 1/2 Coyote's 3.630 in. bore - these pistons install directly into an unmachined standard-bore Gen 3 block without cylinder boring. The 12.0:1 compression ratio achieved by the positive 8.4cc dome matches the factory Gen 3 Coyote spec, maintaining the engine's OEM knock thresholds while delivering the strength and heat resistance of a premium forged piston over the factory cast units.

The 2618 aluminum alloy forging provides maximum resistance to fatigue, detonation damage, and ring land failure under boosted or high-RPM conditions. Mahle's Grafal anti-friction coating on the piston skirts reduces drag, scuffing, and wear at the cylinder wall interface - the same technology Mahle uses across its OEM piston programs. Phosphate coating in the ring grooves and pin bores prevents ring micro-welding and pin galling during the critical break-in period. The forced pin oiler channels deliver continuous oil to the wrist pin interface for extended pin life under sustained operation. Each piston weighs just 373 grams, keeping reciprocating mass low for responsive throttle delivery at the 7,500 RPM redline of the Gen 3 Coyote.

The included 1.0mm / 1.0mm / 2.0mm file-fit performance ring pack reduces ring tension compared to OEM-width rings for lower friction and better sealing - however, ring end gaps must be individually set by your engine builder prior to assembly. Piston-to-wall clearance should be verified with actual bore measurements before installation. This kit is not compatible with the Gen 1 or Gen 2 Coyote (which use a smaller 3.630 in. bore), nor with the Gen 4 Coyote found in the 2024+ Ford Mustang GT without fitment verification. Not for sale in California. Professional engine builder installation required. Sold as a complete set of 8.
