America & Speedmaster DNA Airbox Filter

Using an air/fuel ratio data logger for measurement, this DNA filter consistently gave us the best torque/bhp figures when tested against two other popular brand filters. (see dyno tab).

The DNA High performance air filter is a high quality next generation multilayer cotton gauze oil impregnated air filter. The filter media is made of 4 layers of high quality nafta surgical cotton gauze specialy designed by our R&D department. The cotton is sandwiched between two layers of epoxy coated Marine grade aluminum wire mesh, designed to last a lifetime. The result of the special design and the Hi Tec manufacturing process is a filtration media that has very high flow rates, low restriction, superior dust holding capability, smooths out the air flow stream and lasts a lifetime.

Available for the America and the Speedmaster.

Well made piece of kit.

- 05th November 2017

I put this on my Speedmaster as part of its stage 1 tune. Very easy to fit and I can now hear some intake noise. You can certainly see how restrictive the original intake was when comparing them!
