Driver Saves Over $100 by Buying and Installing Air Filter for Just $25

A car owner was quoted $140 at a repair shop to replace both his cabin air filter and engine air filter. Before agreeing to the service, he checked the retail prices at AutoZone and discovered that both filters together cost only $25, prompting him to replace them himself. The owner mentioned he also had several other maintenance items pending—including ball joints, coolant replacement, spark plugs, oil change, new tires, and possibly a wheel alignment—and saving $140 would significantly ease his expenses. He later filmed a video demonstrating the replacement process: first removing the glove box to swap out the cabin air filter, then opening the hood to replace the engine air filter. The entire job took him about five minutes. Market averages typically place cabin air filters between $10 and $30 and engine air filters between $10 and $20, making a combined price of $25 well within the normal range. Some commenters noted that similar products can be found online for as low as $7 each and advised against purchasing from AutoZone to achieve greater savings. Another user shared a similar experience, recounting how a Hyundai owner, after receiving an $87 quote from a dealership, bought both filters for $25 at AutoZone. AutoZone recommends replacing both the engine and cabin air filters every 12,000 miles or annually to prevent pollutants like dust and pollen from entering the cabin or compromising engine performance.
