DNA High Performance Filter & High Flow Air Intake Plate

(193 customer reviews)

£74.99

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.)

Fits – Interceptor 650

Continental GT 650

Bear 650

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.

DNA filter

Well made good fit goes well with a pair of Powerage short pipes. Bike picks up quicker in lower rev range and seems to breathe better

DNA Air Filter

Ordered the DNA air filter and bracket with express delivery and received them here in South Korea in a matter of days. The air intake sound is much more noticeable (in a good way) and bike performance feels better too.

DNA filter and Tec stinger.

These 2 parts together have changed my interceptor dramatically and I couldn't be more pleased. It can now breath and has more midrange grunt, sounds fantastic and has shed 12kg in weight which has changed the way the bike handles. I did have one issue with an exhaust spring, I contacted Tec and the spring was through my door the next day. Unbelievable customer service and fantastic parts.

DNA Filter for GT 650

Excellent filter, just what I needed to complement the Stinger 2/1 exhaust that I fitted to my RE Continental GT 650. Very easy to install without any effort. I will be buying from TEC bike parts again in the near future.

Excellent quality items, easy to install and paired up with the TEC Big Bore exhaust system, definitely has better performance, especially low down torque.

Air filter is Genetic modification!!

Just serviced the Interceptor650 with a new DNA air filter and an oil change using Silkolene Pro. The bike has been transformed. Much better midrange power and the bike even sounds better. I was not expecting such a noticeable change to the bike. Really worth the money (over the price of an OEM filter). TEC as efficient as ever with delivery, too. 10/10

DNA air filter and bracket seconds to fit and even though it’s hidden it looks great when in place. Top quality product and excellent service from TEC. Thanks

HP Air Filter

Having read the reviews relating to increased engine efficency when used on R.E. Interceptor twins I followed suit and although only had a chance for a brief run with it the change in engine response is noticeable.

Excellent

Brought it my dad for Christmas as he’s wanted one for a while, he’s really happy with it and it gives his bike a bit more of a better sound when riding, also Tec bike parts delivered it really fast, always had a excellent service from Tec bike parts and will continue to use them in the future.

Love it even tho its just an air filter, easy to fit bike sounds great and the engine can now breathe Looking forward to getting more upgrades front tec cheers guys

Surprisingly effective!

I'll admit to being a little sceptical prior to purchasing this, but the difference is very noticeable. Throttle response is smoother with faster pick up in lower gears. Mid-range is more lively and the improvement in exhaust note is just fantastic - I wouldn't say particularly louder, but definitely more throaty with plenty of bass. I don't know if there's any power improvement, but it's certainly putting a big smile on my face. Super easy to fit, also. One of the most satisfying mods I've done on my Interceptor.

DNA High Performance Filter

Excellent product at reasonable price. Very good service from ordering to delivery. Excellent you tube installation video. My interceptor 650 runs a lot better with rhe DNA Performance Filter fitted.

No 1 Upgrade

Given that this is "just" an air filter, it's hard to exaggerate the transformative effect. It feels - and sounds - like a different bike. Quite incredible.

So much better

Noticeably more power in lower revs and adds a great note to the engine.

Worthwhile bit of kit!

Bought the DNA filter and plate which arrived very quickly. Very easy to fit. The filter seemed to perk the engine up and you could almost hear it "breathing" more easily. Quite expensive, I thought but with cleaning, it should last the life of the bike and the OE filters are not cheap! Recommended.

What more can I say

If it breaths better it runs better, and the DNA kit does that exactly without a doubt.

Does exactly what it says in the advert

Nothing wrong with the item but expensive Royal Mail signed for delivery had no useful tracking and was thrown in my garage even though I was at home. Tec sent no emails after confirmation of the order so I didn't know if was on the way.

High performance air filter

Real quality item from Tec fitted easily with good easily followed instructions really need to wait untill you have the full Cannon exhausts back in stock before I comment on performance but have a feeling it will be greeeeaat!! Many thanks Tec, great parts and fast delivery. Now hurry up and get the Cannons on stock!!

Dna filter

I would recommend this upgrade. What I love most is the induction roar. The bike feels that it needs more gas maybe to compensate for the better breathing. I have a fuelx on order to see if this helps.

Effective, easy mod

I’m really happy with the difference this has made to my interceptor 650. Revs much more urgently and sounds great. I’ve monitored fuel consumption since I’ve had the bike and with this filter and plate installed I’ve seen a very slight increase in fuel economy. More fun and more efficiency. Perfect. Great service and quick delivery.

Excellent kit.

The DNA kit has been fitted for a week, and there is a noticeable improvement in engine response. I'm really happy with the outcome. Still running the engine in, looking forward to enjoying the performance once this is completed.
