What is K&N Air Filter Oil?

K&N Air Filter Oil is a 12.25 ounce aerosol can of air filter oil that is designed to work with K&N air filters. K&N is a well-known brand in the automotive industry, producing high-quality and high-performance air filters, intake systems, oil filters, and other products for various vehicles. K&N air filters are made of cotton gauze material that allows more airflow than conventional paper filters, while also trapping more dirt and contaminants. However, to achieve optimal performance and protection, these filters need to be oiled regularly with K&N Air Filter Oil.

K&N Air Filter Oil is a synthetic oil that has special additives to make it sticky and tacky. This helps the oil penetrate the filter pleats and remain suspended in the cotton fabric. The oil creates a barrier that prevents dirt and dust from passing through the filter, while allowing clean air to flow freely. The oil also makes the filter flame-resistant, which is important for safety reasons. K&N Air Filter Oil is compatible with all types of engines, including gasoline, diesel, and hybrid.

What are the benefits of using K&N Air Filter Oil?

Using K&N Air Filter Oil has several benefits for your vehicle and your engine. Some of these benefits are:

– Improved engine performance: By using K&N Air Filter Oil, you can ensure that your engine gets enough clean air to operate efficiently and powerfully. More airflow means more oxygen for combustion, which results in more horsepower and torque. A dirty or clogged air filter can reduce your engine performance by up to 10%, according to some studies.
– Extended engine life: By using K&N Air Filter Oil, you can protect your engine from harmful dirt and debris that can cause wear and tear on your engine components. A clean air filter can prevent up to 98% of contaminants from entering your engine, which can save you money on repairs and maintenance in the long run.
– Reduced emissions: By using K&N Air Filter Oil, you can reduce your vehicle’s emissions and environmental impact. A dirty or clogged air filter can increase your fuel consumption and carbon dioxide emissions by up to 10%, according to some studies. A clean air filter can improve your fuel efficiency and lower your emissions by allowing your engine to burn fuel more completely.
– Reusable and washable: By using K&N Air Filter Oil, you can reuse and wash your air filter as many times as you want, without compromising its quality or performance. This can save you money on buying new filters every time they get dirty, as well as reduce waste and landfill. K&N air filters are designed to last for the lifetime of your vehicle, as long as they are properly cleaned and oiled with K&N Air Filter Oil.

What are the drawbacks of using K&N Air Filter Oil?

Using K&N Air Filter Oil also has some drawbacks that you should be aware of before buying it. Some of these drawbacks are:

– Messy and time-consuming: Using K&N Air Filter Oil can be messy and time-consuming, especially if you are not familiar with the process or do not have the right tools. You need to remove the air filter from your vehicle, spray it with K&N Air Filter Cleaner, rinse it with water, let it dry completely, spray it evenly with K&N Air Filter Oil, let it dry for 20 minutes, reinstall it in your vehicle, and check for any leaks or excess oil. This can take up to an hour or more, depending on the size and condition of your filter.
– Potential damage to sensors: Using K&N Air Filter Oil can potentially damage some sensors in your vehicle’s intake system, such as the mass airflow sensor (MAF) or the oxygen sensor (O2). These sensors measure the amount of air and oxygen entering your engine, and adjust the fuel injection accordingly. If they get contaminated by oil or dirt from your air filter, they can send inaccurate signals to your engine computer, causing poor performance, reduced fuel economy, or check engine lights. To prevent this from happening, you need to make sure that you do not over-oil your filter, and that you clean any excess oil from your intake tube and sensor wires.
– Not compatible with some filters: Using K&N Air Filter Oil is not compatible with some types of air filters, such as paper, foam, or synthetic filters. These filters have different materials and structures that do not work well with oil. Using oil on these filters can clog them, reduce their airflow, or damage them. You should only use K&N Air Filter Oil on K&N air filters, or other cotton gauze filters that are designed for oiling.

How to use and maintain K&N Air Filter Oil?

To use and maintain K&N Air Filter Oil, you need to follow these steps:

– Check your air filter regularly: You should check your air filter every 12,000 miles or 12 months, whichever comes first, according to K&N’s recommendation. You can also check it more often if you drive in dusty or dirty conditions, or if you notice any signs of reduced performance or increased emissions. To check your air filter, you need to remove it from your vehicle and inspect it for any dirt, debris, or damage. If it looks dirty or damaged, you need to clean and oil it before reinstalling it.
– Clean your air filter properly: To clean your air filter, you need to spray it with K&N Air Filter Cleaner, which is a specially formulated solution that loosens and dissolves the dirt and oil from your filter. You can also use a soft brush to gently scrub the filter if it is very dirty. Then, you need to rinse the filter with low-pressure water from the clean side out, until the water runs clear. You should avoid using high-pressure water, as this can damage the filter fibers. You should also avoid using any other cleaners or solvents, as they can harm the filter material or leave residues that can affect the airflow.
– Dry your air filter completely: To dry your air filter, you need to let it air dry naturally in a cool and shaded place. You should avoid using compressed air, heat sources, or direct sunlight, as they can damage the filter fibers or cause them to shrink. You should also avoid squeezing or wringing the filter, as this can distort its shape or damage its structure. You should only oil your filter when it is completely dry, as any moisture can prevent the oil from penetrating the filter properly.
– Oil your air filter evenly: To oil your air filter, you need to spray it evenly with K&N Air Filter Oil, which is a synthetic oil that has special additives to make it sticky and tacky. You should hold the aerosol can about 3 inches away from the filter, and spray each pleat with one pass only. You should avoid over-oiling the filter, as this can cause dripping, pooling, or clogging. You should also avoid under-oiling the filter, as this can leave gaps or holes that can allow dirt to pass through. You should let the oil wick through the filter for 20 minutes before reinstalling it in your vehicle.
– Reinstall your air filter securely: To reinstall your air filter in your vehicle, you need to make sure that it fits snugly and securely in its housing. You should check for any leaks or gaps around the edges of the filter, and tighten any clamps or bolts if necessary. You should also wipe off any excess oil from your intake tube and sensor wires, and reconnect them properly. You should start your engine and let it idle for a few minutes, and check for any abnormal sounds or warning lights.
