Replacement Air Filters for Chevy Silverado 1500 and 2500 Trucks

No other country on the planet loves full-size pickup trucks more than Americans, they symbolize our can-do attitude and repreasent limitless opportunities. The Chevy Silverado 1500 and 2500 has been one of America's go-to full-size pickup truck choices since its introduction. Connected to the idea of hard work and independence, the Silverado offers strong tow and hauling capacities, and continues to embody the notion that although a truck is a tool, it can at the same time possess a pretty face with an amenable personality.

When shopping for a stock replacement air filter, you will find a vaiety of options that fit this trucks airbox. Replacement air filters for the Chevy Silverado are available as typical OEM style paper air filters, performance cotton air filters and performance synthetic air filters. OEM style paper replacement air filters are less expensive than cotton or synthetic air filters, very easy to install, but require replacement roughly every 12,000 to 15,000 miles. After-market replacement air filters made with cotton or synthetic filter media are slightly more expensive to purchase than replacement air filters made with paper media, but because they can be reused over and over again, these options can save you money in the long run. All three of these choices serve their purpose and have their place, so the replacement air filter decision ultimately comes down to personal preference.

Cotton and synthetic replacement air filters can offer your Silverado performance benefits because they are less restrictive than a typical paper air filter which is why we refer to them as an air filter upgrade. A few premier replacement air filter upgrades for the Silverado, in the reusable aftermarket category, are AEMís synthetic air filter (part no. 28-20129), K&Nís cotton air filter (part no. 33-2135), Sectre Performance synthetic air filter (part no. HPR8755) and AIRAID synthetic/cotton blend air filter (part no. 850-135). These air filter elements are technically superior to paper replacement air filters, so choosing specifically which is best for your Silverado may hinge on some air filter 101.

Air filters are measured by their efficiency of filtration, or how much dirt they keep out of your engine, while still allowing for excellent levels of air flow. Itís a difficult task to attain the ideal balance between filter efficiency while retaining optimum air flow. An air filter approaching 100 percent engine protection efficiency levels, for example, would require a filter medium so tightly meshed that air flow would be extremely compromised. Less air spells less power; too much air flow and schmutz gets through. Both the AEM and K&N replacement air filters exceed OEM specifications, as both manufacturers are wholly dedicated to achieving and maintaining that ideal balance, with test results indicating that both replacement air filters increase horsepower and torque, at the same time providing outstanding engine protection for longer periods of time.

Which bring us to the other benchmark for measuring replacement air filters, air filter capacity, or how long an air filter can maintain that tenuous balance between protection and air flow, all during and between service intervals. An air filters recommended service interval is a good method for determining the filter capacity. And again, both the AEM and K&N air filters list their service intervals of reaching up to 50,000 miles before filter maintenance is needed. And both companies provide their own specialized air filter cleaner which makes cleaning a snap.

The one significant difference between these two air filter upgrades, and pretty much the only thing separating them, is how they go about accomplishing that delicate balance between too much and too little. AEM Dryflow replacement air filters do not require oil to achieve low restriction while providing great engine protection. Their synthetic three-dimensional, filtering medium uses both depth loading and structural screen wire to enhance airflow capabilities. While the K&N air filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a specially formulated grade of lightly tacky oil, which creates a dirt magnet effect throughout the cottonís microscopic strands. Combined with the natural character of cotton, which also allows high volumes of airflow, and this too creates a powerful filtering media that provides optimal engine power and protection.

In conclusion, either the AEM or K&N replacement air filters will provide significant engine protection, and performance improvements for a Silverado. The effectiveness of one over another has in fact not been established. The final air filter replacement decision then breaks down to more a personal criterion, like whose logo looks best, or what favorite motorsport hero do they endorse?
