DNA High Performance Filter & High Flow Air Intake Plate


After fully testing the Royal Enfield stock air-box arrangement, we realised it was highly restricted.  This was a combination of a small air-intake plate and a restrictive paper type air-filter.

We have collaborated with DNA filters – a highly respected performance air-filter manufacturer – to bring you this kit.

The kit comprises of a washable high performance filter that should last the life of the bike with careful maintenance.  Also, a high-flow air intake filter retaining plate which holds the filter in place.

The combination of filter and plate dramatically increases the flow and efficiency of the filter.  (See performance data sheet in pictures, carried out on DNA’s state of the art air-flow test bench.)

OEM Air Filter Air Flow: 42.40 CFM

DNA Air Filter Air Flow: 60.40 CFM

DNA Increased Air Flow: +42.46%

DNA Filtering Efficiency: 98-99%

This kit will also save you needing to buy an expensive air filter each time the bike is serviced.

The air filters are supplied pre-oiled and ready to use.

We have dyno tested these bikes with filters fitted and with both standard and all of our aftermarket silencers.  The air flow ratio is safe in all situations.

No re-mapping is required.

Filter and plate are available separately if required.  However, we highly recommend fitting them together.

Recommended by TEC & DNA to use with the DNA service kit.
