...moding the filter and TB have not made more than 2bhp's difference, the intake path is the problem and gives very turbulent flow, we need to smooth this flow to get velocity up and make it longer.
Are you talking about Zetecs here? If so, what in your opinion is the one thing someone should do with a Zetec intake?
Personally I find it hard to believe that new filters won't help, given how numerous the positive testimonials for different filters have been.
