General Product Information (May not be specifically applicable to this item)

The Oil Filter is a low cost part that needs regular replacing. Essentially its role is as the name suggests - to filter and remove dirt particles from the oil as it flows through the engine. It also allows for efficient lubrication of the hundreds of precision moving parts in your car's engine. Many of these parts operate at thousands of movements per minute. Even the tiniest foreign matter in your engine can create excess friction and damage. Oil Filters help prevent potential engine damage from happening. 

Maintaining the oil filter allows for:

• Efficient lubrication 
• Long life engine performance & protection.

While the quality of the oil is vital to the performance of an engine, the quality of the Oil Filter is also crucial to the smooth operation and longevity of the engine. Only Toyota Genuine Oil Filters feature a dual-textured element to capture even the smallest particles. 
There are three main features that determine the quality of an Oil Filter:

The Element
A Toyota Genuine Oil Filter features a dual-textured element - coarse on the outside, fine on the inside. This combination filters particles effectively and resists clogging. Non-genuine brands can be thin and finely meshed, making them prone to tearing and clogging, and as a result could need replacement more often. 

Sealing Capability
A Toyota Genuine Oil Filter uses durable, heat-resistant, non-stick acrylic rubber gaskets. Non-genuine filter gaskets without these features can be prone to rapid deterioration and damaging leaks.

Valves
A Toyota Genuine Oil Filter features two valves - a Bypass Valve which allows vital oil to still flow in the event of a filter becoming clogged, and an anti drain-back valve which prevents oil draining out of the engine and into the oil pan. This valve helps protect your engine from increased wear during cold starts.

Diesel Engine Oil Filter        
The Toyota Genuine Diesel Oil Filter is designed to filter carbon as well as other contaminants. Non-genuine oil filters may fail to filter carbon, causing dirty oil, black smoke emissions, increased fuel consumption and engine wear. That's why you must always insist on Toyota Genuine.
