Air Filter
Built To Keep
Engines Running Clean
Premium Guard air filters deliver superior filtration efficiency and engine protection with near-complete vehicle coverage—from late models to older applications. Built to the highest standards, they keep your engine clean, efficient, and performing at its best.
Optimal Airflow for Enhanced Performance
Engineered for optimal flow, delivering optimal power, fuel efficiency, and smoother acceleration.
Optimal Filtration for Enhanced Protection
Advanced media technology captures more than 99%* of harmful contaminants, shielding vital engine components from dust, dirt, and debris.
Optimal Dirt Holding Capacity
Optimal-capacity design traps more dirt with minimal restriction to flow, ensuring lasting protection and reliable performance throughout the service interval.

Factors That Impact
Air Filter & Engine Performance
Premium Guard thoroughly tests three main factors that define overall filter performance:
Efficiency
Efficiency matters. Premium Guard engine air filters capture up to 99%* of dirt and contaminants, helping your engine breathe cleaner and perform better.
*Except where non-woven media is required to match OEM specifications. Tested per ISO 5011 for air filter performance.
Capacity
Dust-holding capacity measures the total amount of airborne contaminants an air filter can capture over its service life. Premium Guard air filters are engineered for high dust-holding capacity, ensuring long-lasting performance and protection.
AirFlow
Airflow restriction measures how easily air passes through the filter into the engine, based on the pressure difference between the clean and dirty sides. Premium Guard automotive air filters are designed to maximize clean airflow for enhanced engine power, performance, and efficiency.
Air Filter Replacement
Most car manufacturers recommend changing the air filter every 10,000-12,000 miles or once a year, whichever comes first.
Signs It’s Time to Replace
Your Engine Air Filter
Engine Light Comes On
Many vehicles are equipped with an airflow sensor that can trigger the check engine light when airflow is restricted.
Reduced Fuel Economy
When the engine receives less oxygen, it burns more fuel to compensate. A drop in fuel efficiency can signal it’s time to replace the air filter.
Reduced Horsepower
If your vehicle hesitates or responds sluggishly when accelerating, a clogged air filter may be the cause. Replacing it can restore performance and improve acceleration.
Visual Inspection
Premium Guard air filters feature a white filter media to make dirt and debris easier to spot. Inspect the outer and inner layers for visible dust buildup.
Engine Misfiring
A restricted air supply can cause unburnt fuel to leave soot deposits on spark plugs, leading to rough idling or misfires.
Black Smoke / Flames
Insufficient airflow can prevent fuel from burning completely during combustion, resulting in dark exhaust smoke or even small flames from unburnt fuel.
