DNA High Performance Filter & High Flow Air Intake Plate

(27 customer reviews)


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.

    Does what it says it should do. Better power, much more lively & better pick up at low RPM.

  4. John B. (verified owner)

    Easy fit. More induction noise. More grunt.

    Tec were most helpful & quick to respond to inquiry. Filter arrived really quickly, carefully packed & in pristine condition. Super easy to fit, this filter seems to have made several noticeably positive improvements. Firstly on acceleration, the bike now feels like its had an Espresso coffee, it’s more alert & quicker to get going. Secondly, the sound – more pleasing rumble from the Enfield 650 twin, and the induction sound is pure joy. All materials & parts are of quality components, well engineered & constructed. I think a very wise purchase too as filter will last life of my bike saving money & throwing away filters per 3KMiles.
    I’m planning to buy booster plug & other tec parts as am so pleased with all round service/experience.

    The DNA air filter is well manufactured and it is very easy put in place.
    The delivery was very fast. Faster than another item I ordered in my own country !
    It is a good deal to buy the air filter and the retaining plate.

    Thanks to a video, I have learned that it is wise to let the engine runs – without rev’it – for 10 to 20 minutes in order to let the electronic injection to regulate itself. And no need to fine tune or remap the settings of the fuel injection.

    About fuel consumption, it is to early to know the difference. The engine breathes better and the accelerations seem much responsive. it is a bit more loud especially near the air filter.
    When I twisted the throttle hard at the first time, I thought I was overtaken by another motorcycle.
    But no, it was the roar of the engine expressing itself !
