After fully testing the Royal Enfield stock air-box arrangement, we
realized 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. Please see performance data sheet in
pictures, carried out on DNA’s state of the art air-flow test bench.
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.
