B48A20 B20 JE Forged piston 2.0l 16V Turbo Mini Cooper S BMX 125i 320i 420i

JE Pistons forged pistons for the B48A20 B48B20 2.0l 16V Turbo

Made in USA

The forged pistons are recommended from an output of 350 hp.

Thanks to the high-quality aluminum alloy, the pistons are lighter, more stable, more temperature-resistant and can withstand higher loads than standard pistons.

The compression is reduced. As a result, significantly higher pressures can be achieved than with the standard pistons. Even excessively high boost pressures of up to 3.5 bar are no problem with a sensible tuning and corresponding engine setup.

It should also be noted that the webs between the piston rings are 5-8 mm wide (instead of only 3-5 mm as with other pistons).

This is crucial at high boost pressure.

You can opt for the following options:

Compression ratio 9.5:1
82.00 /82.50

22mm standard piston pin or optional HD tool steel +€89.00
