Effective air filtration of the air entering the combustion chamber requires the largest possible working surface. This surface is achieved by densely folding the filter media into the characteristic accordion shape, which performs perfectly during steady driving. But what happens when you put your foot down and the engine starts demanding much larger amounts of oxygen? 🚗
During hard acceleration, the engine generates vacuum that exerts immense pressure on the pleats of the filter element. In low-quality filters, such strong air pressure causes adjacent folds of the media to compress and stick together. This leads to restricted flow and engine choking, which reduces performance and increases fuel consumption. How can this be prevented?
At WIX Filters, we have eliminated this problem. Our precision embossing technology ensures that special stabilizing ribs keep the pleats at perfectly consistent spacing, preventing them from deforming. This provides free, even airflow across the entire filtering surface - regardless of engine load or speed. Stable pleat geometry protects the engine from losing optimum performance.
Do you often come across an air filter that, under vacuum, has bent into a Chinese 8 or completely collapsed inside the housing? Share your findings in the comments! 👇
