If you’re hitting the trails or just cruising through some dusty backroads, you know how important it is to keep your engine breathing clean air. That’s where the K&N off-road replacement air filter comes in. This isn’t just any filter; it’s built for those of us who push our rides to the limit, especially in tough conditions. I’ve been using one on my Yamaha, and I can tell you, it really makes a difference.
First off, let’s talk about the material. This filter is made from cotton gauze, which means it’s not just durable but also highly efficient at filtering out dirt and debris. You’ll appreciate that when you’re out there in the dust, knowing your engine is getting the clean air it needs to perform at its best. Plus, if you’re riding at higher altitudes, this filter keeps the carburetion smooth without needing to mess with jet changes. Just pop it in, and you’re good to go.
One of the best features? It’s washable and reusable. After a long day of riding, instead of tossing it out, you can just clean it up and re-oil it with about 0.83 oz of K&N oil that comes included. That’s right—no need to spend money on replacements every time you ride. And with a flexible frame design, it fits snugly in your bike without any hassle.
In terms of size, it’s got a height of 1.438 inches and outside dimensions of 7.688 inches in length and 7.438 inches in width. It weighs in at just 1 lb, so it won’t add any unnecessary bulk to your setup. And let’s not forget the peace of mind that comes with a one-year limited warranty—K&N stands behind their products.
For those of you with Yamaha bikes, this filter fits a range of models from 2018 to 2022, including the YZ450F, WR450F, and YZ250F. It’s a solid choice for anyone looking to enhance their bike’s performance without the fuss of constant replacements.
So, if you’re ready to give your ride the upgrade it deserves, check out the K&N replacement air filter. You won’t regret it.

K&N, formally known as K&N Engineering, Inc., is the world’s leading manufacturer of washable performance air filters and cold air intake systems. K&N manufactures over 12,000 parts for a wide range of makes and models of motorcycles, cars, SUV, trucks, industrial applications, and more. K&N was founded in 1969 and is headquartered in Riverside, California in a complex of 10 buildings compromising approximately 400,000 square feet. K&N also operates facilities in China, England, and the Netherlands.
In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N) developed a revolutionary idea for an air filter—one that could perform under the demands of dusty, dirty off-road environments. After experimenting with different types of filter media, they discovered that an oiled cotton design allowed the filter to capture contaminants efficiently, and also be washed and reused. It was right then and there that the original K&N High-Flow Air Filter was born. Fifty years later, K&N is still dominating the industry with leading filtration technology and innovative products that offer extraordinary protection for virtually every application out there.
What Makes K&N the Best?All K&N products undergo rigorous testing to make sure they adhere to and exceed demanding quality standards. These tests include power, torque, and airflow tests to confirm that the intake products are maximizing power boost while retaining engine safety. The company stands behind its product 100 percent with some of the most extensive warranties in the business – a Million Mile Limited warranty. K&N’s performance air intake systems are designed to improve airflow to the engine by replacing the restrictive factory system with a single aerodynamic tube and highly efficient filter media. The systems are available in two materials. The first is Polyethylene, which is used to produce 57 and 63 series intake systems. The second one is aluminum, which can be found on the 69 and 77 series intake systems.
Advantages of K&N IntakesThe benefits of adding a K&N intake system to your car are plenty. Firstly, it will increase your vehicle’s horsepower and torque, while also improving fuel economy and the appearance of your engine bay. What’s more, it will deliver a satisfying, more aggressive exhaust note at higher RPMs. Each K&N intake includes an oversized filtering unit, which can go up to 100,000 miles between cleanings, unlike paper filters that can become clogged easily and cannot be washed or reused. In other words, with K&N products, you will never have to replace your air filter again.
Why Install an Aftermarket Intake?Internal combustion engines all work as large air pumps. Air goes in, fuel is added, combustion occurs, and air goes out. This means there are two ways of increasing power: getting more air into the engine or making it easier for air to get out of the engine. Your air intake is responsible for filtering air before it enters your engine. Dirty air can damage the engine cylinder walls, so a high-quality filter is a must-have item. With a K&N system or filter, you increase airflow through the filter, which means more air is pulled into the engine. K&N does this without reducing filtration qualities, so your engine will live a long life.
