When it comes to quality, technology factors do make an enormous difference. And the quality difference between Genuine Nissan Oil Filters and aftermarket oil filters lies in the design. The anti-drainback feature of a Genuine Nissan Oil Filter minimizes oil drainage from the filter when the engine is off. When the engine is turned on, oil is immediately supplied to the upper engine components, minimizing friction at a critical time.
Genuine Nissan Oil Filters provide more filtration area for maximum filtering capacity and longer effective service life. Nissan uses only premium quality filter paper with a fine texture to filter out impurities. Most poor quality oil filters have a smaller filtration area, as much as 40% less, and use poor-quality paper, which is more likely to clog and tear. Genuine Nissan oil filters use an O-ring seal made from NBR rubber, which resists heat and oil and ensures a complete seal even if the filter is hand-tightened.
Aftermarket filters often use a flat cut synthetic seal that is less reliable and more prone to leakage. The outside cases on Genuine Nissan Oil Filters are rigid and sealed with double seams to prevent leaks. Poor-quality aftermarket filters may not be firmly sealed, resulting in a loss of oil pressure that could damage the vehicles engine.
Remember! Genuine Nissan Filters are specifically designed for Nissan engines to ensure optimum performance and reliability. If an aftermarket oil filter does not meet Nissan's specifications, the new vehicle warranty could be affected in the event of an engine failure!
"A little bit of dust is not going to make much difference to my engine." Not so! In order to operate efficiently, an engine needs an enormous amount of clean air - about 9,000 litres for every litre of fuel burned. This air must flow smoothly into the engine without dust and other harmful debris. If unfiltered air is permitted to enter the engine it can cause harmful abrasions to cylinder walls and piston rings, resulting in premature wear. Clean, unrestricted air is required for efficient combustion, resulting in maximum engine power and fuel economy, while maximizing exhaust emissions.
"Paper is paper, especially when it comes to filtering air." Not True
Genuine Nissan Air Filters use only a high-quality, viscous-type filter paper that has been oil-permeated. Because the paper is sticky, dust and other foreign matter adheres to the paper as air passes through it. Trapped dust is permeated by the viscous oil and actually becomes a porous filtering material itself! The dry paper used in low-quality aftermarket air filters can clog prematurely, restricting vital air flow to the engine and reducing power output and fuel economy.
Fuel filters are designed to protect the engine from damage by straining out impurities such as dust, water and metal particles before they reach the fuel pump and fuel injectors (or carburetor) and cause poor engine performance and potential damage. For fuel-injected engines operating under higher fuel pressure levels, Genuine Nissan fuel filters are constructed from stainless steel and aluminum alloys to assure air-tightness and pressure resistance. For carburetor applications, the casings are made from shock-resistant, semi-transparent nylon resin and feature a bypass fuel passage in the event that water in the fuel is frozen. Of course, Genuine Nissan Fuel filters are engineered specifically for each engine application, using superior quality filter paper for straining efficiency and maximum fuel flow capacity.
