I saw in this thread mention that the rotary Tire Valve is OEM??

Does anyone have this come stock with their 8s? Cause I sure know mine came with the normal cheap looking black caps. :(

They're OEM, but not standard equipment. You can get them here. (http://www.trussvillemazda.com/PartsStore/index.cfm/results/Parts/2004/Mazda/RX-8)

A fellow on ebay is selling rotary valve caps and license plate bolts for the 8 and 7. I got both sets for both cars and I am pretty happy with them.
