This modification improves the performance?

@Kluzak92 NO! It is 13 times smaller in surface area than the proper filter, so the holes are 13+ times bigger. That means lots of big pieces of dust and dirt to damage the turbo and engine. It degrades performance rapidly and I guarantee you will have less torque and power in PS or BHP by NOT using the original paper filter in the air filter box. The box is designed in a particular way so altering it lowers your power and torque and increases noise. BoyRacers are conned all the time with them.
