Piston ring set NPR for Toyota Supra MK3 3.0l 7MGTE STD

Since NPR Group was born in 1934, we have contributed to the ever-increasing motorization of the world. Our main products, piston rings and valve seat inserts, are adopted by major automobile manufacturers not only in Japan but also overseas. 

NPR rings have a longer service life than serial rings, dissipate piston heat into the cylinder and regulate the oil film on the cylinder surface, leading to long-term maintenance of adequate compression in the combustion chamber.
