Review on Stens 500 736 Piston Rings Black by Steve Stone

Using this product, our team found that the performance of our automotive engine has significantly improved. The piston rings have a perfect seal and provide an enhanced compression that results in an improved exhaust performance. We also appreciated the durability and quality of the rings .The only downside is the higher price compared to other standard piston rings. Nonetheless, we will surely purchase again as it is worth the investment for engine performance improvement..
