ENGINE AIR FILTER
Thousands of litres of air, mixed with fuel, power the internal combustion engine of a vehicle. Impurities such as dust, pollution, and other dirt must be removed from both the air and the fuel. Though gasoline is filtered several times before reaching your vehicle’s engine, the air is simply found around the vehicle, which is why an extremely efficient air filter is necessary.
A vehicle is most energy efficient when the engine air filter is clean, since the air/fuel blend is ideal. When the filter is dirty, some fuel doesn’t burn, the engine becomes less efficient, and the engine and exhaust system get clogged up.
This change is gradual, and drivers are unlikely to notice a problem until the Check Engine light comes on. Changing the engine air filter is easy and inexpensive. A certified NAPA AUTOPRO technician can check or replace the filter during an oil change or scheduled maintenance. A new air filter will restore your engine and help you get more bang for your buck at the pump.
