AMSOIL Air Filters
PDF Filtration Products Brochure
AMSOIL oil-wetted foam air filters keep oils and engines cleaner for longer periods with the most effective air filtration available today. AMSOIL air filters provide superior performance in all three critical areas of filtration: efficiency (dirt-stopping), capacity (dirt-holding) and resistance (air flow). AMSOIL air filters are uniquely designed to hold wear-causing dirt while allowing only clean air into the engine for better performance, better fuel economy, lower exhaust emissions and longer engine life. Also, AMSOIL air filters are washable and reusable for thousands of miles of trouble-free service. Tests prove AMSOIL air filters have up to 350 percent greater life expectancy than competitive air filters.
The AMSOIL TS Air Filter, for passenger vehicles, features two layers of oil-wetted polyurethane foam, which provides a network of interlocking cells that trap particles yet allow a constant flow of clean intake air for outstanding engine protection and performance.
The AMSOIL POD Air Filter, for small engines, features an oil-wetted foam filter element and an inner spring that shakes dirt off the filter and harmlessly away from the engine.
Provide Full-Depth Filtration
AMSOIL TS and POD Air Filters are "full-depth" filters that trap and hold much more dirt than do conventional "surface-type" filters. The polyurethane foam used in AMSOIL Air Filters is much thicker than the thin layer of paper used in conventional filters. The foam's thickness allows for more filtering area and more capacity to trap dirt over a longer period of time.
Improve Air Flow
AMSOIL air filters allow more air into the engine than conventional air filters do and better maintain their air flow over the life of the filter. The intake surface of conventional paper filters quickly becomes obstructed with dirt, which impedes air flow. AMSOIL air filters distribute dirt throughout the foam depth, allowing unobstructed air intake to the engine.
Form Tight Seal
The flexible polyurethane foam of AMSOIL air filters provides a consistent, tight seal between filter and housing. Unlike conventional filters, which often fail to seal properly due to their hard rubber seal, the foam of AMSOIL air filters conforms to irregularities on the bottom and top of the housing, forming a tight seal when the housing is secured. Intake air must go through the filter before reaching the carburetor.
AMSOIL air filters are available for most car and small engine applications. The AMSOIL "Oil and Air Filters Application Guide" (G-194) is a comprehensive reference guide covering most makes and models of automobiles and light trucks. If you cannot find an AMSOIL air filter to fit your application, please call the AMSOIL Technical Services Department at (715) 392-7101 for availability and price quotes on filters to fit your application.
The AMSOIL POD Air Filter is suited for applications such as motorcycles, rototillers, small garden tractors, lawn mowers or farm implement equipment. The AMSOIL POD Air Filter is adjustable to fit carburetor throats ranging from 1 to 1-7/8 inches. It also has a special adapter for Briggs & Stratton carburetors. Other throat sizes are available.
AMSOIL Oil Filters
The AMSOIL Super Duty Oil Filter (SDF) is designed to provide maximum filtration while meeting the high flow demands of modern automobiles. The AMSOIL SDF contains a high-tech media blend of cellulose, fiberglass and synthetic fibers that offers the best possible balance of long life, high capacity, and overall efficiency.
Traps Dirt Throughout Media Thickness
The AMSOIL SDF has a lofted fiber depth-type media that traps dirt throughout its entire thickness for exceptional filtering efficiency. It keeps oil clean and free of wear-causing contaminants. The AMSOIL SDF Oil Filter provides up to 100 percent more capacity and up to 20 percent greater efficiency than other filters provide. It is ideal for use with extended oil drain intervals.
Built for Rugged Performance
The AMSOIL SDF has a heavy-duty case of drawn steel. The case is double-crimped at the base with rolled-under seaming to withstand extreme pressure surges and road shocks.
Assures Oil Flow with Relief Valve
A relief valve is provided to assure ample oil flow and maintain proper engine oil pressure. It prevents oil starvation in the engine in the event the oil filter by-pass valve in the engine fails.
Prevents Oil Drainage During Engine Shutdown
On filter installations where the mounting is sideways or upright, dirty oil could drain out of the filter when the engine is shut off. The AMSOIL SDF has an anti-drainback valve that keeps trapped contaminants in the filter when the engine is not running.
AMSOIL INC. recommends changing the AMSOIL SDF according to the following guidelines.
In gasoline-fueled engines using any AMSOIL motor oil except AMSOIL XL-7500 Synthetic Motor Oil, change the filter at 12,500-mile or six-month intervals, whichever comes first. In gasoline-fueled engines using AMSOIL XL-7500 Synthetic Motor Oil, change the filter at 7,500-mile or six-month intervals, whichever comes first.
In diesel-fueled large truck engines, change the filter(s) at the engine manufacturer's recommended oil change interval. In diesel-fueled light trucks, including pickups and vans, change the filter at 7,000-mile or six-month intervals, whichever comes first.
When using an AMSOIL Oil Filter with conventional motor oils, refer to the owner's manual for the recommended oil filter change interval.
AMSOIL By-Pass Oil Filters
The AMSOIL By-Pass Oil Filter provides the best possible filtration protection against wear, oil degradation, rust and corrosion. Working in conjunction with the engine's full-flow oil filter, the AMSOIL By-Pass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately ten percent of the oil at any one time and traps the extremely small, wear-causing contaminants and water that full-flow filters can't remove. The AMSOIL By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
Approximately 60 percent of all engine wear is caused by dirt particles in the 5 to 20 micron range. These particles can get inside the precision clearances between engine components and cause severe damage. While full-flow oil filters generally stop contaminants no smaller than 25 to 40 microns, the AMSOIL By-Pass Filter effectively stops particles 1/10 of a micron in size, substantially reducing engine wear.
Prevents Oil Degradation, Rust and Corrosion
Water enters motor oil as a combustion by-product or as a condensate. Water contamination of the motor oil can cause extreme engine damage. Water causes metal surface rust and corrosion, which increases friction and wear and deteriorates the close-fitting tolerances between engine components. In addition, water reacts with other oil contaminants to form corrosive acids, which also damage metal components. The AMSOIL By-Pass Filter removes water, reducing the risk of oil degradation, engine rust and corrosion.
Extends Oil Drain Intervals
Because the AMSOIL By-Pass Oil Filter removes water and particles smaller than one micron, it significantly increases the time oil can safely be left in the engine. In fact , engines using AMSOIL Synthetic Motor Oil and an AMSOIL By-Pass Oil Filter routinely show much lower rates of engine wear - even when the oil is used for significantly longer drain intervals - than engines using conventional products and conventional oil drain intervals. That saves motorists time and money and helps protect the environment by creating substantially less used oil.
