When it comes to engine performance, air filter adjustment is a key element of vehicle maintenance. The purpose of changing the filter is to enhance engine performance by increasing air flow in the engine, allowing more fuel to burn in less time. But what are the pros and cons of a high flow air filter?In theory, a high flow air filter can boost power by 3 to 5 HP and also increase torque. This is because cold air is denser and therefore combusts better, which improves engine performance.
However, most renowned tuners consider the actual benefit of increasing engine performance to be quite low. At least, if there are no other modifications, such as Chiptuning, Turbo- or Upgrading the compressor. On the other hand, when installing an open filter, not only fresh air, but also warm air enters the engine. As a result, the engine temperature rises and the oxygen saturation in the combustion chamber decreases. In addition, an open sports air filter can sometimes also absorb larger particles, which can cause considerable damage to the engine. In conclusion, a high flow air filter can be a good option if you want to increase power, fuel efficiency, or simply reduce the hassle of changing your air filter regularly.
However, it is essential to consider all aspects before making any changes to your vehicle's air filter.
