Correct OEM valve stem caps?

Which are the correct OEM valve stem caps?
Gray with nipples on the top, or gray that are smooth on top?

Anyone know who may sell them?

Rob,

Gray and smooth .... I found some aftermarket (not easy to find gray at all) that are close however not 100% perfect ... think I posted photos over on turbotransam.com

Mini dice work well!

Rob photo of a used OEM cap and the only gray ones I could ever find that are close and looks ok.

Audi Part Number N-90872901

Retail for 80 cents each.

Lots of times you can ask a parts guy and he will go back by the tire machine and just grab you a couple.

Hope this helps.

hit up the spare tires in the junkyard on 80's and 90's cars

So the top pic is the OEM one correct? That what the ones look like that were on my ht car wheels.

Well the oem caps on t-types are gray but with the nipple on top. That's what those guys do for finding oem caps.

yes the top one is the OEM cap

You mean my chrome caps aren't OEM?

Most cars with tire pressure monitoring system have gray caps. dodge ones look pretty good.

rock the green ones where people will think u have nitrogen in the tires

Thanks for the info!
