I would be very surprised if this makes any difference at all, this is the same company that says their air filters give an increase in horsepower and acceleration.
But each to their own 🙂
my car has a k&n air filter so maybe its tru lol
that would be a great post for the 340hp sc Astra thread on vx220.dot lol the toys would be every where
I do remember someone telling me the tiny k&n air filter I used to have on would not make more than 240hp it did make 273hp that day lol
in truth tho I only use a k&n filter due to its wash ability and reusability the other types of foam filters work but wont come clean the dirt gets deep in the pile and wont come out
