Finding the right size air filter for your truck can be a challenge, but with the right information and a few simple steps, you can easily determine the size of air filter that is best suited for your vehicle. The first step is to consult the owner's manual, which usually includes a specific part number. If the owner's manual is missing, you can search the Internet for a digital version or use a reputable parts supplier's website to find the part number. The engine air filter is specific to the size of the engine, as it has the important job of preventing dirt, dust and harmful particles from entering the engine and causing damage. To measure the air filter, use a measuring tape and make sure to record the length, width, and height correctly.
Round all measurements to the nearest whole number in inches to get the standard size. If you need help measuring the air filter, you can contact a professional. Most standard filters are valid for one year or between 12,000 and 15,000 miles. However, if you drive on a lot of dirt or gravel roads or live near a beach with lots of sand in the air, then a high-performance filter with a lower micron index and higher filtration efficiency could be the best option for your needs. Most air filters have a replacement schedule that is specified in the user's manual or on the company's website.
Additionally, most online air filter retailers have a custom air filter page where you'll find a choice of custom sizes. It is important to understand how size affects an air filter's ability to flow maximum amount of air to the engine. In general, filters with 1- and 2-inch air filters are installed in standard air conditioning systems, while 3- to 6-inch filters are installed in larger air conditioning systems. 4- to 5-inch air filters are usually better at providing a perfect fit that prevents dirty air from passing through. Like an oil filter, replacing the engine air filter at recommended intervals is critical to maintaining proper amount of air flow and protecting the engine. One of the main advantages of thicker air filters with larger folds is that they don't need to be changed as often. K&N tests have shown that in most two- and four-cylinder carburettors, air flow is greater when the diameter of the air filter is large compared to its height.
Plus, they come in more than 30 different sizes, so it can be difficult to find the right size air filter.By following these steps and understanding how size affects an air filter, you can easily determine which size is best suited for your vehicle. With this knowledge in hand, you can make sure your truck has clean air flowing through it at all times.
