K&N 77 Series Polished Air Intake Kit 77-2556KP
30 days returnmoney back
The K&N 77 Series high flow performance metal air intake kits for pickup trucks and SUV's combine outstanding performance with under-the-hood style. If performance and horsepower aren't enough, the visual appeal of air intake shining under your hood should make you a believer. The metallic finishes of the 77 series air intake are bold and beautiful. Factory air intake systems can restrict air flow between the air filter and the engine, reducing the benefit of a K&N Air Filter alone. This weak spot can seriously reduce airflow and rob a vehicle of its natural horsepower. K&N 77 Series air intakes virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine with a mandrel-bent aluminum tube. The aerodynamically engineered K&N aluminum tube drives a large amount of air into the engine, ultimately giving you power. These air intakes are available with polished aluminum or gunmetal grey powder tube finishes, designed to exceed your expectations and then some. With an oversized high-flow conical air filter design, this system increases surface area and dust capacity. The oversize air filter is also designed to capture more dirt giving a longer life before cleaning and upkeep is required (up to 100,000 miles).
- Available with a polished, chrome-like, or a silver aluminum tube
- Mandrel-bent tubing allows for less restrictive air-flow

K&N Product Warranty
Million Mile Limited Warranty
K&N O/E Replacement Air Filters and Air Intake Systems purchased from Authorized Dealers are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.
What Is Not Covered By Our Warranty
Any K&N product used for 1: any type of racing or competition; 2: any off-road use, custom or modified applications; 3: any off-road or dual sport motorcycle/ ATV use; or 4: any illegal highway use, marine, or industrial applications. All K&N Air Filters not covered by our million mile warranty are warranted against defective materials or workmanship for one year from date of purchase with no mileage limitation. This includes K&N Air Filters sold for ATV's and off-highway or dual-purpose motorcycles.
Incorrect Cleaning or Use Voids Warranty
K&N Air Filters should be cleaned every 50,000 miles for normal highway use, more often in dusty conditions. Cleaning should be done with K&N cleaner and air filter oil (or comparable air filter cleaner and oil). Use of compressed air, or chemicals not specifically designed to clean and re-oil cotton air filters (i.e. gasoline, transmission fluid, motor oil, lightweight oil, or diesel fuel) will void the warranty. Any damaged, abused or modified K&N Air Filters will not be warranted.

Tom McGann, CEO
Engine Protection Limited Warranty
Unlike many companies, our warranty for O/E replacement air filters and intake systems does extend beyond the replacement of a defective K&N part. For the original purchaser of the product, our warranty covers any engine damage or related costs incurred as a direct result of the use of a properly installed and maintained K&N O/E automotive replacement air filter or intake system on the specific vehicle for which the product was designed to be used by K&N. This includes reasonable vehicle repair costs directly related to an engine problem caused by the failure of a K&N product. Furthermore, we warrant that using our product will not result in a vehicle warranty denial. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages not listed above.
We will promptly reimburse the consumer for the cost of the repair if a service provider denies warranty coverage as a result of a K&N product or claims that a K&N product has caused harm to your engine or vehicle. In order to receive reimbursement, we require each of the following:
- The consumer must provide a written statement or repair order from the dealership or service provider in which the dealership or service provider blames the problem or warranty denial on a K&N product.
- The service provider or consumer must provide K&N with all allegedly damaged parts. Many states have laws that require a service provider to retain all parts replaced during a vehicle repair, unless given consent to dispose of the parts by the consumer. K&N will pay the shipping cost to recover these parts.
- The consumer must provide proof of purchase of the K&N product along with cooperation in helping us investigate the claim.
Once these steps have been completed, K&N will contact the service provider and collect evidence to support their claim. In the event we are not provided with sufficient evidence, we reserve the right to reject the claim and will use our best efforts to assist in establishing your rights toward the service provider under warranty or other provisions.
We strive to exceed consumer expectations. Customer service can be reached at 1-800-858-3333.
