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.

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.

Conclusion – this comment after testing various brands of filters.

At the beginning of testing we were sure that the K&N filters would walk away with top honours, simply because they have been around for years and everyone uses them for tuned engines. As testing developed, the results were starting to give a different picture, the DNA's kept coming out on top when used on the Triumph twins, it didn't matter if it was an airbox filter or pod filters, the DNA's were living up to their reputation as a high performance filter.
An aftermarket filter is usually a one off purchase as they can be cleaned and reused many times in their life time and you're unlikely to purchase another filter for the bike in your ownership period. With this in mind, it's a good investment to make sure you get one that flows best on your bike.
