78.5mm MAHLE Power Piston set for B6 1.6L engines.
 
One of the original concepts by Maruha. This is made with 4032 Forged material, different than conventional forged pistons.
 
Set at 78.50mm compared to the standard piston outer diameter of 78.0mm for NA6 and NB6.
 
Compatible with stock ECU.
 
Normally during engine rebuild, a slight overbore is performed to erase the scratches on the cylinder.  If you are aiming to increase the displacement, use a larger piston.
The slightly larger 0.5mm over size seeks both reliability and retention of stock ECU.
 
Made by Mahle, one of the top racing piston manufacturers. OE Supplier to F1, Ferrari, Porsche and other super cars.
