yep, guit-guit on ebay has OEM rings from NIPPON and they are awsome! I just put some on my friends B16a and they are soooo amazing. He got them, 4 top compressions, 4 2nd comp's, and 4 oil controls. I gapped them and set them to factory positions with a fresh hone the motor was like new again. And the price? $50 shipped new for all!!!
