Description
DNA Mazda RX8 MK3 Stage 3 AirBox Kit:
The DNA Stage 3 AK-RX8MK3-S3 Air Box Kit is designed to replace the stock air box and increase the Airflow, Power, Torque kai Throttle response.
Spesially developed for Race & High Performance road applications.
Attention!The Installation must be carried out by a qualified mechanic.
The following procedure is necessary if you use the DNA S3 Air Box Kit:
LEFT SIDE
RIGHT SIDE
3. Install the heat shield in the engine bay where the air box used to be. Bolt the heat shield using the 2 stock bolts at position A & B and ‘push lock’ the 2 front studs, in the stock rubber grommets at position C & D.
4. Now you must install the MAF body supplied by DNA.(see paragraph No. 9 before installing the MAF) Attention! There is a flow direction. The MAF body must be installed as shown below:
The DNA filter side has 5 thin grooves that match the filter. The car intake side has 3 large grooves. Additionally there is an arrow engraved on the body showing the flow direction.
5. Install the stock MAF sensor on the DNA MAF body using the 2 M4X10 Allen bolts supplied by DNA. Following install the MAF as shown below, using the inox clamp supplied by DNA:
6. Remove from the stock air box the 2 rubber grommets A & B :
7. Install the grommets on the DNA heat shield. The rubber grommets are necessary for securing in place the engine plastic cover.
8. Connect the MAF sensor
9. Install the DNA filter, DO NOT OVER TIGHTEN! And the plastic engines cover.
WARNING! Be sure that the MAF body has been installed correctly in the DNA filter and the air flow passage is nice and smooth! The filter / MAF body connection is a precise connection, all 5 grooves of the body must match the ribs found in the filters ‘neck’ and the filter must sit square with the body. It is recommended that you try to connect the two parts before installing them on the car, in order to understand how they connect.
A ‘smooth’ air passage is absolutely necessary for the RX8 to perform flawlessly!
DNA has designed a very unique ‘clamp on’ filter for this application, which features a streamlined venture and ‘round’ top in order to eliminate ‘turbulence’, increase the air flow and not ‘mess up’ the MAF sensor. See below cross section of this New DNA filter:
10. Bolt in place the transparent Plexiglas cover using the 4 M5X20 Allen bolts & washers supplied by DNA. Congratulations you have finished installing your new DNA Stage 3 KIT!
Follow the above procedure each time you service the filter. Filter should be serviced approximately every 6.000-9.000 km. Use the dedicated DNA Service Kit DSK-2001 (sold separately) to clean and re-oil, following the instructions included with the service kit.
Notice: Re- mapping your ECU is recommended if you want to fully take advantage the high flow.
Power by quality you can trust!

We, at DNA, proudly introduce a filter that can last the life of the vehicle. Strict quality control for construction & materials, chosen only by their highest quality, are some of the factors that allow us to offer a Lifetime Warranty!
The Anatomy
This is what Power is made of!
A DNA High Performance Filter is a high quality, next generation multilayer cotton gauze, flameproof, oil impregnated air filter.

This very special cotton is designed by DNA's R&D engineers for High Performance filtering purposes. The basic media is a non woven surgical cotton gauze with a modified TEX & THREAD, with extremely high strength of break. This unique cotton media, actually is a “hairy hybrid” featuring extremely high air flow rates and excellent filtering efficiency that exceeds 98%.
FAQs About DNA Filters

Human "technology" inspiration!
The technology that our DNA filter uses to clean the air is surprisingly common to all of us. It is part of our body; we use it constantly to stay alive! It is part of the Human respiratory system that filters the air we inhale! Tiny moistened hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose with the breathed air. The DNA filtering cotton media is exactly that, millions of tiny fibers that are oiled! This “hairy hybrid” as we call it, is a genius combination of cotton fibers per square millimeter. The Tex & Thread, of this unique cotton, is a result of intensive research and testing, by DNA’s development engineers. The “hairy hybrid” impregnated with DNA’s special filter oil, is transformed into the remarkable DNA media that provides very high filtering efficiency and extremely high flow rates.
Trap "enemies" by static charge!
We designed the DNA filter to aquire a positive static charge as the air passes through the pleated and oiled filter media. This weak static chargewill very effectively “pull” on the oiled cotton fibers, the debris and dust that are in the air; remember in science class at school, the pen rubbed against wool that can attract small bits of paper, experiment? This is exactly what happens, as air flows through the filter, debris even as small as 5 microns will change course and stick onto the fibers, regardless if the “holes” between the fibers can be as large as 150 microns! The first layer of debris on the fibers will then absorb some oil, get statically charged and become part of the filtering media! And guess what, it will start attracting new debris assisting the cotton media in its filtration chore! Finally, debris will continue building up on the surface of the filter, as air passes through, until it is totally covered.
Extreme testing environment
Our filters have being successfully tested even in the harshest environment during the DAKAR Rally! Through Argentina, up to the Andes, and down to the Atacama Desert in Chile. The dreadful “Fesh- Fesh”(Guadal) fine powder desert sand of the Atacama Desert, was successfully kept out of the race engines, outperforming the foam filters! So the myth is busted, the DNA filters can successfully be used in any environment, on and off the road, in the desert or the outback, DNA will be there to protect you.
Here comes increased torque & power
The DNA filter will also smoothen out the air flow stream, as it passes through the filter, reducing turbulence and sending smooth clean & fresh air towards the engine intake, increasing torque and power. Additionally to the high air flow, smooth and unified air flow is very important. This explains why we see a decrease in power output when testing a bike or car on the dyno “without” a filter as the circulation of air in the air box is disturbed and the result is turbulence and low power output.
