Appears to be high quality, blue. Installation was easier than I thought. Hopefully this will keep oil from getting on the spark plug on cylinder 3 on my 2001 Prizm. The old one was dry and cracked, maybe that was the problem. Remember to take some RTV silicone with you in case there are any bumps or seams e.g. B. where the timing chain is located. Rough spots can develop by simply prying them off with a screwdriver if you're not careful.
