I'm about to get my mums 2005 Honda Accord re-ringed, so I got TPR piston rings. I made arrangements for it to be bought and sent to me but when I showed the box to my mechanic he said they're fake and that he would very much preferred to be the one who did the buying. My problem on the other hand is with the ring size; It's 0.25. Is that the right size or will the cylinders need to be bored, cuz I really dont want to do that.
What do the experts in the house think.
