Though small and unimpressive compared to other components found under the hood, air filters are absolutely vital to engine performance. This is because their main function is to prevent harmful pollutants and particles from entering the engine through the air intake system. When you drive with a worn-down or clogged air filter, your truck engine may even consume more fuel with less mileage, decrease in horsepower, or start making unusual noises. That’s why you must stay on top of timely air filter replacements.
