Keep your Cadillac running smoothly with the ECOGARD XF65618 Premium Fuel Filter. This is a direct replacement part that fits a bunch of Cadillac models from the mid-2000s, including the CTS, SRX, and STS with various engine sizes like the 2.8L, 3.6L, 4.6L, 5.7L, and 6.0L (check the full list in the description to confirm it fits your specific year and engine). It replaces OEM numbers like ACDelco GF897, FRAM G11296, and GM 25763176. Changing your fuel filter is a simple maintenance task that can have a big impact. A clean filter protects your expensive fuel injectors by trapping dirt and rust particles from the gas tank. This helps prevent problems like hard starting, rough idling, poor acceleration, and bad fuel economy. This filter is built with a multi-layered material for excellent filtration, and it has precise inlet/outlet connections for an easy, hassle-free installation. Give your engine the clean fuel it deserves!
