MAHLE Motorsport PowerPak Forged Piston Set – BMW B58 / Toyota Supra (82mm, 10.5:1)
$1,275.10
OVERVIEW
MAHLE Motorsport PowerPak forged pistons are the proven upgrade for high-power B58 builds in BMW and the Toyota GR Supra. Forged from 2618 alloy at the stock 82mm bore and 10.5:1 compression, the PowerPak set arrives complete with rings, pins and clips — everything needed for the piston side of a rebuild.
SPECS
- Forged 2618 aluminum alloy for maximum strength under boost
- 82.00mm bore; 10.5:1 compression (matches OE)
- Set of 6 pistons with Grafal anti-friction skirt coating and hard-anodized top ring groove
- 22mm floating wrist pins; CNC-finished pin bores
- Thermal Barrier Coated (TBC) crown option for higher-heat/high-boost builds
- Complete PowerPak — rings, pins and clips included
PARTS INCLUDED
- 6 forged pistons
- Wrist pins and round-wire lock clips
- Piston ring set (1.2 / 1.5 / 2.0mm)
TECH RESOURCES
- Rebuild hardware not included — rod bolts, head/main gaskets and ring gapping are required separately
- 2618 is a race forging — expect slightly more skirt-to-wall clearance and some cold-start rattle versus OE cast pistons
- Professional engine assembly required
