The ECOGARD S5274~E8 Engine Oil Filter is engineered to provide superior filtration and protection for a wide range of vehicles, including select models from Cadillac, Chevrolet, GMC, Oldsmobile, Pontiac, Saab, and Alfa Romeo. Designed to meet or exceed OEM specifications, this filter ensures optimal engine performance and longevity by effectively removing harmful contaminants from the engine oil. Constructed with high-quality materials, the ECOGARD S5274~E8 features a synthetic media that delivers 99% efficiency in capturing particles as small as 25 microns. This high-efficiency filtration helps maintain engine cleanliness and reduces wear, contributing to extended engine life. The filter's design includes a silicone anti-drain back valve, which prevents oil from draining back into the engine during shutdown, ensuring immediate lubrication upon startup and reducing engine wear. The filter's robust construction includes a heavy-duty filter body capable of withstanding up to five times the normal oil pressure, providing durability and reliability under various operating conditions. The precision-engineered baseplate with forged threads ensures a secure and leak-proof seal, preventing oil leaks and maintaining consistent oil pressure. For optimal performance, it is recommended to use full synthetic motor oil with the ECOGARD S5274~E8 filter. This combination enhances engine protection and allows for extended oil change intervals, reducing maintenance costs and downtime.
