In some cases, the oily coating the performance filters have also caused issues further up the system
Stick with the original filter, and also make sure they add the one with the winter foam on the front of it, this catches even more dirt before it enters your combustion chamber, and don't be fooled by the YouTube flow rate comparisons you see.
If you want more performance, take some weight out of the car 🙂
