Are DNA Performance Filters REALLY worth it for your Royal Enfield? My answer might surprise you!!

Does a performance air filter really give us that much power gain? I'm going to give you a quick overview of how it installs, performs, and if it's really worth your hard earned $!!
Huge thanks to ‪@my-enfield612‬ and ‪@stuartfillingham‬ for the wealth of knowledge they both have provided to RE 650 owners worldwide. Thanks guys!

I don't care i just love riding my intercepter i didn't get it to go fast just to ride in style

[@jewciferrides]

Nothing wrong with that either! 👍 Style for days!

[@Guvnarides-WI2020]

I have the DNA kit and booster plug combined with a TEC 2 into 1 Stinger exhaust. The throttle response is definitely crisper but the main gain is the sound of that motor, its gorgeous!

[@jewciferrides]

Absolutely, it's a shame not to let these motors sing! I also have a booster plug on the way, curious to see how it affects performance.

[@ride_the_wind]

@@jewciferrides Do you have a euro4? I have a euro5 and was wondering if a booster plug actually works

[@jewciferrides]

@@ride_the_wind I have heard the Euro5 ones will throw a code after a while with the booster plug unfortunately.

[@danielkerr4100]

​@@ride_the_windi think tecbikeparts have a video of it working with euro5

[@philc4520]

Sounds good bro.

[@SeamusMacMattain]

you should check it out with a full header swap from Hitchcock's and a Power Commander, that will open her up well, sound and power delivery will both be increased noticeably... edit: I have a 22 GT with euro4 ECU and I have the parts I mentioned above plus the K&N air filter as well as the shorty slip ons from Enfield Precision

[@ScottOgle-t2z]

Great video!

[@jewciferrides]

Thanks man!!

[@ssdravidian]

Hows the top end power delivery? Another video suggested that you may need to tune it, because with the DNA, the air fuel mix is pretty thin and you loose out on the top end...

[@jewciferrides]

I ended up adding a booster plug to help with A/F ratio, I'd say the low end was affected more than top end for me, and the BP fixed that and smoothed out the throttle response for on/off bigtime. Check out my vid on that too!

[@andreastomblin2137]

Totally agree with you man about the DNA filter I fitted one after watching Stuart Fillingham (top man) but still have stock pipes. Love your pipes the sound is awesome. Where did you get them from?

[@jewciferrides]

There's man. Love the sound too, The guy at the gas station was telling me all about Red rooster, gursewak, and the others , but you saw how his face lit up when he heard mine. I bet the filter makes a big difference even with stock pipes! I Got the mufflers from low brow customs (upswept cocktail shakers, flipped over to lay flatter) and the heat shields to cover the joints came from @revzilla . Thanks for watching!

[@andreastomblin2137]

@@jewciferrides Thanks a lot ride safe!!!

[@GrampsD63]

Always start with the Intake side on any modifications. Doesn't do any good to add free flow mufflers if it can't flow . Sounds great!

[@jewciferrides]

Very true, unless you're just after sound not performance. Thanks!

[@GrampsD63]

@@jewciferrides Aaannndd like you said you sometimes see a flatening of the stock torque curve with just slip-ons. Us crafty old wrenches seen it once or twice before 😉

[@georgewashington7574]

You mean like starting at the intake port side of the head? Since if that’s the bottle neck point all of these modification won’t matter. However, If the intake side of the head isn’t the restriction yes, this modification will help. Waste of money in some bikes, while it’s helpful on others.

[@ramanujnath6078]

thous silencers looks so good how much price of those silencers.

[@ramanujnath6078]

???

[@jewciferrides]

They are Emgo Cocktail Shakers, upswept version. I flipped them upside down to make them lay flatter. They were about $150USD

[@ramanujnath6078]

@@jewciferrides its look So cool

[@hemantv.5409]

If we use it in stock muffler then it will be as significant as it is on after market exhaust...? I think freeflow exhaust are lighter then stock,so here is major role of waight loss.

[@jewciferrides]

Aftermarket exhausts are 1/3 to 1/2 the weight of stock so yes, much weight savings. I did the exhaust first, so not sure how the intake on stock exhausts would be. Not as lean as intake + exhaust at least.

[@2wheelssaiyan]

I appriciate the advice to switch that small ass bolt for a go pro screw! I never even thought of it! 😂 totally worth it

Makes life so much easier!

"HIGH PERFORMANCE FILTERS" 🧐 I've seen a lot of videos about changing the air filter, they all say the performance will improve. But no one could measure or calculate, only words...How much percet performance was increased exactly?

[@WyreForestBiker]

You think its revving lower for a given speed !! ?? ... did the filter magically change the gearing of the bike too ? 🤣😂🤣

[@jewciferrides]

Not magic. Science 🤣

[@oldgeezerproductions]

Exactly right, The engine at a specific RPM, will always turn the rear wheel at the same rotational velocity for the same transmission gear selected. My INT 650 does 60 MPH at a tad under 4,000 RPM in 6th gear with a standard (130/70/18) tire on the rear and a standard (100/90/18) tire on the front. Either Jewcifer put on a smaller front tire (

[@oldgeezerproductions]

@@jewciferrides Ha, not really. Please see my comment above.

[@jewciferrides]

@@oldgeezerproductions you are both correct, I'm still newish to bikes and didn't understand how the gearing and rpm are tied together. I appreciate the info! 👍 Also I agree 4k is easy to listen for with these rather loud cans.

[@oldgeezerproductions]

@@jewciferrides Thanks for that. Knowing (and admitting) that you can be wrong is an important step toward wisdom, in my opinion. You have a good delivery and speak well and the wind noise is something you will fix as you make more videos, I'm sure.

[@theradiantchild]

What about adding a booster plug or fuel X?

[@jewciferrides]

That was one of my biggest questions, because I had heard so much about It being less pleasant to ride without one of those installed, after doing the air filter. In my experience it's actually smoothed out at low revs, stop and go traffic, etc. I am sure it would make more power with a tuner of some sort, but from a rideability and safety perspective, the ECU should be able to learn just fine after 15 minutes of idling and one or two gentle rides.

[@theradiantchild]

@@jewciferrides I'd be afraid of backfires and running too lean without a booster plug

[@jewciferrides]

@@theradiantchild No backfires, same decel pop and crackle as it was stock only mufflers swapped. The ECU does read the O2 sensors and learn in that first 15 minute idle, and so far I feel like it's kept itself from running too lean. That being said, I'm sure there are still power games to be had by adding one of the fuel controllers!

[@janengelund7901]

I put a boosterplug on my FZ6 yamaha 4 bange, it made a big difference, no stalling and a more beefy midrange 👍👍

[@arthol51]

Seriously guys why bother. If you want to go fast buy a supersport. Royal Enfields are great fun bikes. Maybe they may make an 850 one day but until that time just enjoy.

[@danielkerr4100]

Maybe they don't want a gay sportsbike but just want to a little more out their enfield
