The Tomei Piston Ring Set consists of 3 different ring types: the oil, top, and 2nd. When rebuilding an engine that is going to be making a lot of power, it is a good idea to upgrade the piston rings. Tomei is one of the leaders in Nissan tuning and has made these pistons rings available in 3 different sizes.
