Tech Notes:
- Anodized Ring land option adds 3-10 days to
manufacturing time and can be recommended (but is not required) for
high boost N54 engine builds.
- Pistons are delivered 'first oversize'. Stock
Bore is 84mm, so 84.5mm is the default size to allow for
honing. If another size is needed, please request this.
- What compression should you chose? Most tuners
have found OE compression works extremely well up to around
600-700WHP with different fuel configurations, if you have a goal
higher than this, consult a VAC tech or your tuner.
Expedited production services are available for applications not
in stock; 2-3 week ($$) , 1-2 week ($$$), or 4 Day ($$$$).
Please place a request at the end of your order in the notes
section if you would like this service. You won't be charged if

Many pistons look alike, however; our CP Pistons use spot-on
clearances, specification, dimensions, and metallurgy that are
specifically engineered to perfect compatibility with each BMW
application and engine technology, and tested in real world
use.
