 “One of my favorite AMSOIL products because it once again adds a unique touch to a common product and unlike the oils, it’s visually pleasing as well. We get a lot of feedback from users of these. Take your old oil wetted gauze and hold it over a lamp, then compare to this – or even better take an oil test with the oiled type, then with the AMSOIL intake filter and see the reduction of dirt.. “

More Cold Air = More Horsepowe; AMSOIL Air Filters Flow!

The basic purpose of the air intake system and these cold air intake filters is to bring cool air from outside the engine compartment into the engine. The cooler air is denser than the air found within the hot engine compartment. The denser charge contains more oxygen than warmer air, providing better combustion through a more effective air/fuel mixture.

Another advantage of most specialty-equipment cold air intakes is their consistent diameters and the absence of sharp bends, both of which help to eliminate turbulence in the air stream.

Large and Growing Market of Cold Air Intake Kits

According to research done by the Specialty Equipment Market Association (SEMA), a new air intake system is among the first modifications a consumer makes to his or her vehicle. Since changing the air filter alone cannot eliminate air restriction built into the vehicle at the factory, replacing the factory air flow assembly includes replacing the filter, air box and air path. SEMA reports sales of air intakes are over 300,000 every year.

While intake kits were initially sold only for performance-type applications, they are now also being marketed and used as a way to boost fuel economy in SUVs, minivans, trucks and more.

AMSOIL EaAU is Absolute Efficiency

AMSOIL Ea Air Induction Filters fit most of the popular intake systems available. They provide improved cold air intake and a level of engine protection only an Ea Filter can provide. AMSOIL is currently offering nine Ea Air Induction Filters with varying lengths and widths. These filters have flange IDs of 3?, 3.5?, 4?, 4.125?, 4.5? and 6?. Since these filters offer a universal fit, AMSOIL provides the dimension sheet below that customers can use to determine the proper filter for their applications. Customers can easily match the best filter for their application.

Cleanable with air or shop vacuum

The AMSOIL Ea Cold Air intake Filter is cleanable and long lasting. AMSOIL recommends cleaning the Ea Air Induction Filter when designated by the restriction gauge if the vehicle is so equipped, or according to operating conditions. If it is used in extremely dusty environments or in a performance vehicle, more frequent cleanings may be required. Just clean yearly between 15,000 or 25,000 mile intervals.

Cleaning the Dry Intake Air Filters:

Carefully remove the filter from the housing. Clean the housing with a shop towel, being careful not to knock contaminants into the air inlet. Filters can be cleaned by carefully vacuuming the filter media on the dirty side, or by holding the filter with one hand and carefully blowing the filter media at a 45-degree angle on the clean side using low-pressure shop air (15-20 lbs. psi).

Unique Design

To increase filter surface area and the volume of air entering the engine, the top of many popular Ea Air Induction Filters (EaAU) is cut away. The media is inserted in a conical form pointing toward the direction of airflow.

Extreme Cold – No problem for AMSOIL Synthetic Engine Oils

Start Your Winter Mornings – and Your Vehicle – with AMSOIL Synthetic Lubricants

John Baker |Jan 14, 2015 8:46:00 AM

Long before coming to work at AMSOIL, I owned an Oldsmobile Cutlass Ciera that refused to start on below-zero mornings. I blamed it first on the battery and then on the car itself. “It must be a lemon,” I reasoned.

Cold Temperature Protection
Turns out it was probably the dirt-cheap conventional motor oil I used in those days. Unfortunately, there was no friendly AMSOIL Dealer in my neighborhood to teach me that conventional oils contain paraffins (wax) that can thicken in the cold enough to prevent the crankshaft from turning fast enough to start the car.

The Cold Crank Simulator (CCS) Viscosity Test is one method of testing a lubricant’s cold-flow properties. The test is used to determine the internal fluid friction in motor oils with a “W” grade designation. It measures the amount of energy required to overcome the resistance present in a lubricant that has been collected at temperatures from 23°F (-5° C) to as low as -31°F (-35°C), depending upon the anticipated SAE “W” classification of the oil being tested.

The CCS Viscosity Test simulates an engine’s ability to turn over at cold temperatures. Gauges monitor rotations per minute, amperage draw and motor input. A universal motor is run at a constant voltage to drive a rotor, which is closely fitted inside a stator and immersed in the test oil. The viscosity of the oil at the given test temperature determines the speed of the rotor and amperage draw; thicker oil results in slower speed and more amperage drawn. Speed and amperage drawn are then converted to centipoise (cP).

CCS results showing a lower cP number indicate lower viscosity. Oils that are thicker at low temperatures (high cP number) tend to exhibit more resistance and require more energy to pump and circulate and display a higher cP number on the CSS test. A higher cP number at a given temperature is directly correlated to a greater amount of energy required to turn an engine over, and it also indicates a greater potential for starting difficulties. Most importantly, CCS results suggest a lubricant’s ability to be circulated at a given temperature and its ability to provide wear protection.

As seen in the graph, AMSOIL Signature Series 5W-30 Synthetic Motor Oil outperformed several leading synthetic motor oils in a CCS test.

AMSOIL versus others in cold flow properties



Solve oil starvation at start-up

Extreme cold can cause conventional motor oil, transmission fluid and gear lube to thicken, starving vital moving parts of necessary lubrication. In many cases, thick motor oil will prevent vehicles from starting. Cold, thick transmission fluid results in delayed or sluggish shifts and inadequate protection for bearings, valves and other critical parts. Thick gear lube, meanwhile, requires more energy to turn the gears, reducing fuel efficiency. Because gears and bearings in the axle housing are splash-lubricated, conventional gear lubes that are too thick at cold temperatures can starve internal components of lubrication, which can cause excessive wear and premature failure.

Conventional petroleum lubricants thicken because they often contain paraffins (wax). While modern refining techniques remove most of the wax from petroleum oil, some wax-like molecules remain. These wax-like molecules are soluble at ambient temperatures above freezing, but crystallize into a honeycomb-like structure at lower temperatures and cause circulation problems. At startup, this can leave working parts unprotected while the lubricant warms to a temperature that allows it to flow.

AMSOIL synthetic lubricants ( do not contain paraffins, so they remain fluid in sub-zero temperatures. Watch the video to see what happens when AMSOIL Signature Series Synthetic Motor Oil ( and a conventional oil are cooled to -40º. While the conventional oil fails to flow from the beaker, Signature Series remains fluid and delivers 36% easier and faster cold starts*. This means it can reach vital components faster, providing more immediate engine protection and reduced wear.
