DNA filters. Little cheaper then K&N but just as good! No need to talk about the pro’s and con’s but if you want to know more please do read this;

Individual aftermarket airfilters are often called ‘pods’ or ‘powerfilters’. This gives the idea that by adding such powerfilters you add instant power to your bike.
In an ideal world, that would be true. The bike would rev in all ranges and have massive torgue throughout the powerband. But… It’s not the ideal world.

A bike’s carburetor system is a well balanced machine. You introduce fuel and air to the compression and KABOOM!. The right mixture is very important. Just like when you shower – if the water’s too hot you can either add cold or take hot away. It’s partially the same with carbs.

When you add powerfilters, you disturb the mixture. Adding powerfilters make the mixture poor, because too much air is being introduced. Too much air and the explosion will be dull or poor, not enough air will make a rough and partial combustion. Both are not what you want. Cheap pods like EMGO are about the worst stuff you can buy. These filters are not intended to run in pairs because they are not calibrated. Let’s say filter 1 lets 100% air thru, changes are filter 2 is at 85%, filter 3 is at 105% and filter 4 is at 90%. It’s nearly impossible to get them right. You will get the bike running, and changes are you will get it running ok.. Well, ‘ok’ is not why you started the build in the first place aye? Get it right.

The reason these filters are called powerfilters is because they give you the option to enlarge the mixture entering the combustion chamber. Logically, just like in the shower, you need to make sure there’s more gas going in aswell to make the mixture balanced again. To do so, you will have to take the carbs apart and install bigger main and pilot jets. That way, you have the same ratio of fuel and air, but more of it. Usually, more is better.

The question everybody always asks; ‘I’ve installed pods from brand X on bike X and now the bike runs shit. What size jets do i need?’
The answer is a tricky one because nobody knows the answer. It’s trail and error to get them right as every bike is different. Usually we’d say go up 10-15% on main jets and 1 step in pilots. We’ve had bikes run well with 5% bigger mains and also had a GN125 from that went from 67 to 135. You see, there’s no rule or calculation for it.

Now that you’ve read all this, buy these filters, dial them in and be amazed about the powerincrease. And yes, we also have jets in the shop.
