Increase Horsepower in Your Pickup: New Intake Systems for 2017-2018 Silverados

Engineered for 2017-2018 Chevrolet Silverado models, K&N® performance air intake systems offer a guaranteed increase in horsepower and torque for Chevy Silverados—featuring a washable performance air to help protect against engine contaminants, and an aerodynamic tube design that increases airflow and provides a boost in power.

The 2018 Chevy Silverado 1500, 2500, and 3500 models are consistent with the classic American brand’s reputation for quality engineering. Good towing capacity, masculine design, and powerful engine options help distinguish the Silverado from the crowd.

K&N PERFORMANCE AIR INTAKE SYSTEMS BOOST HORSEPOWER

If you’re looking to boost the horsepower in your Silverado, consider a K&N performance air intake system—designed to keep airflow to your engine cool, efficient, and smooth. Many factory intake systems have baffles and other components that can obstruct airflow, create turbulence, and subsequently create heat, resulting in less efficient engine combustion. By replacing the full stock system with a more aerodynamic tube and High-Flow Air Filter™, the engine receives a greater volume of airflow—giving you a guaranteed increase in performance.

AERODYNAMIC INTAKE TUBE INCREASES AIRFLOW

In a typical factory air intake system, air must first pass through a restrictive disposable paper filter before traveling through a complex system of tubing—often featuring tight bends, baffles, and other airflow obstructions—that can cause air to swirl and become turbulent. Excess turbulence causes the molecules within the air to collide, which subsequently increases the temperature and lowers the density of the air, reducing the efficiency of engine combustion.

K&N intake tubes are engineered to give the airstream a smooth, unobstructed path—keeping engine air cooler, and increasing the amount of oxygen available for combustion.

HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTION

Typical stock disposable filters are only able to “surface load”—dust collects on the surface of the media, which over time reduces the filter’s ability to allow a high volume of airflow to pass through. High-Flow Air Filters™ feature a “depth loading” design, in which multiple layers of cotton fibers allow for particle capture on multiple levels, without significantly reducing the efficiency of the filter itself. In addition, a pleated design helps increase surface area—allowing for significantly greater contaminant capture per square inch of media over a typical paper filter.

The oversized, conical shape of the filter included with K&N intake systems allows for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). When the filter does need to be serviced, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each intake and filter is designed to last for the life of your vehicle.

High-Flow Air Filters™ feature an oiled, layered design, and are available on all K&N intake systems aside from the Blackhawk Induction™ systems, which have a filter composed of synthetic, non-oiled media.

HEAT SHIELD HELPS PROTECT INTAKE AIR FROM HIGH TEMPERATURES

K&N intake systems also feature a custom powder-coated steel heat shield, which helps protect the air filter and intake air from high engine temperatures. The heat shield installs onto the lower factory air box and retains the fresh air inlet.

INSTALLATION

K&N cold air intake systems are designed to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 90 minutes or less, and requires only simple hand tools. Detailed instructions are included in your kit, and installation videos for many vehicles are available on the K&N website.

WARRANTY

Each intake system comes with a 10-Year/Million Mile Limited Warranty. Furthermore, using a K&N replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.

INTAKE SYSTEM OPTIONS

For many vehicle applications, multiple options of K&N intake systems will be available. 69-Series and 77-Series intakes feature mandrel-bent aluminum intake tubes, while 57-Series and 63-Series intakes have high-density polyethylene intake tubes. 71-Series intakes are from the Blackhawk Induction™ line, which feature a black powder-coated aluminum intake tube and a black oil-free synthetic filter. Please view the specific product pages for details on each intake type.

DYNAMOMETER RESULTS

After installing your new K&N air intake system, you can look forward to a guaranteed increase in horsepower and torque. On a chassis dynamometer, a 2014 Chevrolet Silverado 1500 4.3L with the stock air intake was recorded at 243.50-hp at 5,285 RPM, and after installation of the 77-3085KP the same vehicle was recorded at 253.52-hp at 5,285 RPM—an estimated increase of 10.02-hp. The torque was also improved from 239.66 lb.-ft on the stock air intake to 253.20 lb.-ft with the 77-3085KPa total estimated increase in torque of 13.54 lb.-ft at 3,548 RPM. You can buy with confidence under the 10-Year/Million Mile Limited Warranty, and the assurance that you’re receiving a top-quality, extensively tested product.

FAQs

Will using a K&N® replacement air intake system void my factory warranty?

No. In the United States, in order for the manufacturer of a warranted product to void or deny warranty coverage of a repair due to the use of an aftermarket part, the manufacturer must provide proof that the aftermarket part is the cause of the necessary repair. These rights are protected under the Consumer Products Warranty Act of 1975 (also referred to as the Magnuson-Moss Warranty Act).

Are K&N® performance air intake systems or RK-series custom air cleaner assemblies emissions legal in the U.S.?

Performance intake systems are legal for street use in most areas of the United States.

In California, and in specific regions which have adopted California air quality regulations, only CARB-exempt performance intakes are legal for street use.

Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

Can a K&N® product cause my Check Engine Light or Service Light to come on?

It is possible that the Check Engine Light may come on after installing a K&N air filter or performance intake system. This does not necessarily mean that there is something wrong with your air filter or intake; sometimes, the higher air flow and lower restriction provided by the K&N product will uncover an existing mechanical or electronic issue with your vehicle. In rare cases, you may have a K&N product which was manufactured outside of its design tolerances, causing sensors in your vehicle to read data outside of their normal expected values. In either case, the K&N Warranty Department can work with you to narrow down the cause of the Check Engine Light and correct the issue.

How much horsepower does a K&N® cold air intake add?

Dynamometer tests indicating horsepower and torque increases over the OEM intake system will appear on the "Product Details" page for each of our performance intake systems.

What does a cold air intake do for a car?

Cold air intakes allow for increased airflow to your engine, which results in an increase in torque and acceleration for your vehicle.

Can cold air intakes improve gas mileage?

In theory, a cold air intake could increase the gas mileage of your vehicle due to improved airflow which allows the engine to run more efficiently and require less fuel. However, K&N does not make any guarantees in terms of increased gas mileage with the use of our filters or intakes.
