It's easy for aftermarket parts to have the same physical appearance as OEM, but the only way to predict long-term durability is through relentless cycle testing in tortuous environments. APA engineers exercise OEM components to failure to establish performance and durability baselines, then cycle-test our prototype products to simulate real-world operation for the expected lifespan of the part. Environmental testing subjects components to alternating temperatures, pressure extremes, vibration, UV radiation, and continuous contact with harsh substances such as fuel, coolant, transmission fluid, and engine oil. Any issues with design or material are quickly identified and rectified prior to production. This painstaking process helps maximize the lifespan of URO and Autotecnica components, and truly sets APA Industries apart from its competitors.
