My Peugeot air-cooled engine kept overheating, climbing all the way to 137°C, which caused poor performance and made long rides stressful. I knew I needed a solution, so I designed this custom air vent cap to improve airflow and reduce engine temperature. After testing, the results were amazing — the temperature dropped to 70°C, and the engine ran smoother and more reliably. The vent cap comes ready to mount with holes, making installation quick and hassle-free.
