Oil filters help protect your engine by trapping dirt and other contaminants while allowing the oil to flow to the engine. Genuine Toyota Oil Filters are designed specifically for your Toyota engine. Features of the Genuine Toyota Oil Filters include:
A bypass valve, which alleviates restricted oil flow in the event of a clogged filter.
An anti-drainback valve, which prevents oil from draining out of the engine and into the oil pan, helping to protect your engine from increased wear during cold starts.
A filter element which effectively filters contaminants and maintains the engine's lubrication capability during the maintenance interval. By comparison, a lesser quality filter element might clog during Toyota's recommended maintenance interval leading to engine wear, seizure or other problems. Some non-genuine oil filters do not meet all of Toyota's stringent specifications
