I agree Mark, but despite large numbers of modified cars in Japan, Australia and New Zealand making massive power with air filters like that, Malcolm still won't believe they can be, so I decided to prove it using theory. In the real world there's lots more variables that come into play, like air density and temperature for a start, but that's another story... ;)
