High Performance Air Filters and Replacement Air Filters

 

Do aftermarket high performance air filters add horsepower and torque compared to stock?

Yes, aftermarket performance air filters can increase your horsepower and torque. If you are upgrading from a brand-new OEM factory filter, you may notice a slight difference, but the true results are typically discovered on the dyno or the racetrack. At the same time, your engine will enjoy increased fuel efficiency, but only if you can keep your throttle foot away from the floor board. 

 

How Often Should You Change the Engine Air Filter?

The best answer is to follow the owner’s manual suggestion for your vehicle and engine. However, if you drive in more adverse conditions, such as dirt and salty roads, Accesspeed suggests inspecting and (when needed) changing your air filter more frequently. Make sure you document the mileage each time you replace your air filter.

 

What are the common signs and symptoms of a bad air filter?

  • Check Engine Light comes on.
  • Noticeable reduction in fuel economy.
  • Noticeable reduced in performance.
  • Air filter appears very dirty upon inspection.
  • Engine misfires or sputters.
  • Unusual engine sounds.
  • Smell of gasoline when starting the car.
  • Black sooty smoke or flames exiting the exhaust.

 

Does changing the air filter make a difference?

Replacing a dirty air filter can increase fuel efficiency and improve performance. A dirty, clogged, or damaged air filter limits the amount of air flowing into your engine. This limitation forces your engine to work harder, reducing performance and fuel efficiency.

 

Do aftermarket air filters improve performance?

Yes, aftermarket performance air filters can improve performance, as proven by dyno and track results thousands of shops and racers.
