    Apply the K&N filter advantage to your engine oil with a K&N oil filter

    If you've been interested in cars for any length of time, you've probably heard of the K&N air filter. A K&N air filter employs a simple philosophy that works very well: Get more air into your engine, make it cleaner, and do all that without ever needing to be replaced. Sound too good to be true? A K&N air filter uses a special filter media made from cotton gauze and oiled with K&N's special filter oil. The combination of the gauze media and the filter oil make for an extremely difficult barrier for dirt to get past. At the same time, though, the K&N air filter doesn't gradually choke like a standard paper air filter does. Instead, the dirt captured by the K&N air filter acts to filter out even more dirt! Your engine gets a steady diet of clean air in greater quantities than even a brand new paper filter can provide, and more air equals more horsepower. Finally, when the K&N air filter is dirty, you don't pitch it in the trash: You simply wash and reoil the filter media using K&N's recharge kit. The K&N air filter is guaranteed for a million miles, so it's obvious the system works. So what's the trade-off? Well, a K&N air filter costs a little more up front, but when you consider all the paper filters you won't be buying, a K&N air filter becomes an absolute steal. They're available for most cars and trucks on the road today, so order your K&N air filter and feel the benefits of increased airflow.

    It only makes sense that the world leaders in high-performance air filtration would expand their horizons to include a full K&N cold air intake. After all, you've probably already come to count on your K&N filter to provide you with additional airflow and exceptional filtration. Take your air intake one step further with a K&N cold air intake. Why a cold air intake? It's simple physics: Cold air is denserheavier, if you willso it contains more oxygen molecules per cubic inch. The more oxygen there is available to your cylinders, the more fuel they can potentially burn. Are you starting to get the picture? By drawing intake air from outside the engine bay, where it's cooler and denser, your K&N cold air intake gives your engine more oxygen to work with. The result is a noticeable boost when you stomp on the loud pedal, and with no detrimental effects on your motoryou're not forcing anything to happen. You're simply freeing up the intake, so you don't have to worry about scattering engine parts all over the road by installing a K&N cold air intake. The crown jewel in the K&N cold air intake is the K&N filter itself, which ensures gobs of clean air can get into the intake. If you want extra power without a lot of work, installing a K&N cold air intake should be the first order of business. Dollar for dollar, the K&N cold air intake is about the smartest purchase you can make.

    Even if it weren't for the advanced filtration you get from every K&N oil filter, there's one feature that makes them worth their weight in gold: A nut is welded to the top of the housing allowing easy filter removal. Simple, elegant, and, if you've ever had scalding oil drench your arm as you pounded a screwdriver through a filter housing, brilliant. But what would you expect from a K&N oil filter? After all, these guys are pretty much at the head of the class when it comes to advanced filtration products. The K&N oil filter is no exception. The performance features of a K&N oil filter begin at the housing itself, which is made from thicker metal to provide a higher burst strength. That's great peace of mind for you guys running high-volume, high-pressure oil pumps. To prevent dry starts where most engine wear takes place, the K&N oil filter also has an anti-drainback valve built in (where one can be used), and the rubber gasket on a K&N oil filter is lubricated from the inside. That means no more leaks and no more double-gasketingthe gasket on your K&N oil filter will come off smoothly every time.
