I was about to buy a replacement piston-rings set for forged Mahle 90.5 pistons, but there are 2 sizes available :
1.5 x 2 x 4 and
2 x 2 x 4.
Unfortunately I don't have my rings set with me to check it, do you know wich size I have to get? Pistons/cylinders are new, what size are they out from the box of the Mahle kit? I need a replacement set only for one piston, since I broke one ring while mounting
Thanks!
