Description

The Rothsport RS-30A is an oil inlet check valve engineered for specific Porsche 911 and 930 models, covering years 1972-1989 (and 1976-1989 for 930). This common issue, particularly in cars that sit for extended periods, often results in excessive smoking upon startup. By installing the RS-30A, you can effectively mitigate this problem.
