What pistons are these? *URGENT*

[Diamond Star Werks]

Yeah I would agree sounds like a bunch junk. It wouldn't matter if NPR did have several companies making pistons for them. NPR would just have them make them the way NPR has always and sold them. Or else they wouldn't bee NPRs. If the manufacturer made them different from the way NPR wants I don't see NPR using them. Wanna know for sure just call NPR and ask "Hey, do you sell pistons with five different markings?" 30 min sounds like an automated message .

IT depends on what you buy from ebay. Npr pistons and rings are very high quality. I buy all my engine parts from an ebay store called mizzumo.

NPR makes the OEM pistons. So yes they are good.

sounds like really bad quality control and that worries me... if they cant send a consistant product.. sounds like chineese crap parts to me..hense again why i do not buy the important stuff from ebay... id stay away from ebay stores, and i would stick to private sellers if they have brand name parts and picture of said part. go to extreme psi dude they ahve the cheap good stuff and they wont eff you over like someone in china would.
