Ram Truck 1500 Performance Air Filters for Trucks

Performance Air Filters for Trucks

Are you looking to increase your engine's intake of fresh, clean, and thoroughly filtered air? Then, consider investing in a premium air filter from RealTruck. Air filters are an integral component of your vehicle's air intake system. Air filters are positioned at your engine's air inlet, forcing air through a super-fine media to filter dirt, dust, and debris to prevent oil contamination and internal damage. 

Additionally, high-performance air filters flow a higher volume of air than your vehicle's factory airbox and restrictive paper filter, ensuring maximum airflow into your engine's intake, efficient combustion, better mileage, and increased power.

Aside from conventional intake air filters, your vehicle also utilizes a cabin air filter, which filters debris and particulate matter from the HVAC system to ensure only fresh, clean air blows into the cabin.

Air Filter Types

Truck air filters come in various configurations, from material construction to alternate designs. Let's examine them closely to determine which is suitable for your application.

Oiled Vs. Dry

Depending on the brand and model number, air filters may feature different types of filter media. Though several constructions exist, the most common are oiled cotton and dry synthetics—but what are the key differences?

Oiled Air Filters

Oiled-cotton air filters feature tightly wound, high-flow cotton filter media saturated in a filter-specific oil. The cotton filter media is highly efficient at filtering sizable particulate matter. However, it's less efficient at filtering ultra-fine particles—that's where filter oil comes into play. Smaller particles that would otherwise be able to pass through the cotton media become trapped in the oil, thus increasing the filtration rate. These filters are typically washable and serviceable, featuring an indefinite service life.

Dry synthetic filters feature synthetic media that doesn't require oiling. They are ideal for dirty, dusty environments, as they feature similar filtration and efficiency without using tacky filter oil that can attract excessive dirt, clogging the filter and hindering performance. Like oiled cotton filters, dry synthetic filters are typically washable and reusable.

Universal Vs. Direct Fitment

Other variables include the type of fitment, including universal and direct.

Universal

Universal air filters are typically conical in shape and come in various dimensions, including flange size, height, length, and width. These aftermarket air filters are engineered for custom air intake systems or to replace the filters included in aftermarket air intakes. Typically, modifications of your vehicle's factory intake system are required.

How Often Should You Clean or Replace Your Air Filter?

Engine air filters should typically be replaced or serviced every 15,000 miles or annually, whichever comes first. However, there are some exceptions. If you notice that your air filter is filthy or has collapsed, it's likely in need of a replacement/cleaning. Additionally, some driveability symptoms to look out for include: 

• Loss of power

• Difficulty starting

• Poor idle

• Excessive black smoke from the exhaust pipe (running rich)

Cabin air filters last a similar duration, typically requiring a replacement after 15,000 miles. Symptoms that your vehicle may require a cabin air filter replacement include: 

• Poor airflow from the vents

• A damp, musty odor with the air conditioner or heater running

• A noisy blower/fan

• Audible whistling from the air vents
