Check the outside and inner layers of the filter paper for dust and debris. <u>Reduced Fuel Economy</u>: When engines get less oxygen, they consume more fuel. If you notice fuel economy going down, you may need to replace the air filter. <u>Engine Misfiring</u>: Restricted air supply results in unburnt fuel exiting the engine as soot residue. Soot accumulates on the spark plugs, which can cause the engine to misfire. <u>Reduced Horsepower</u>: Replacing the air filter can improve acceleration or horsepower. If your car doesnt respond well or jerks when you step on the accelerator, the engine may not be receiving the air it needs to perform. <u>Black Sooty Smoke or Flames</u>: Poor air supply can result in fuel not burning completely during the combustion cycle. Unburnt fuel exits the car through the exhaust pipe, possibly resulting in smoke or flames. Driving conditions Dusty roads Humid climates Congested roads and heavy-traffic areas
