Phil Borley, Technical Director of Stobart Honda commented: 'The air flow on the DNA filters, is equal to the HRC kit equivalent product. Our bikes have benefited from the superior filtration of the DNA filters, compared to the HRC Kit filters. The resultant power, as a back to back measure on the Dyno with the similar HRC filter was also equal. All in all an extremely good product, which I would definately recommend to both racing teams and road users'
Philip Neill, Team Manager Tas Suzuki: 'Our technical team have carried out extensive testing with all available air filters in an attempt to maximise air flow in comparison to the standard unit, whilst at the same time not lose any filtration quality. Following two successful years using DNA filters in the most extreme circumstances [IOM TT], I can confirm that Tas not only gained horsepower on our GSXR 1000 and 600 but I also believe that DNA filters protect our engines better than any other'.
