DNA Air Filters

[madmal64]

Hi all

My ape is having a bit of a major service and I have decided to fit a DNA filter.
Would like to know if any other here have tried or use these air filters and any pros or cons with them

Got a DNA in out ape at moment
its a bit hit and miss really, only real advanage of an aftermarket over fractory is they are reuseable by washing/oil

lots of debat saying stock at better for bike etc etc, but personal perference, both bikes have aftermarket filters

I ran a DNA in the 12 and was pretty happy with it, 4hp increase from the dirty factory filter to the clean dna I'm told for a ZX12

No ECU mapping problems on the RSV? Or did you run some dyno time and get it sorted that way?

The DNA filter in the Zed sorted the 4000-5000rpm flat spot. I can roll on in top gear at 100km/hr without asthmatic wheezing and hurried downshifts now.

well the rsvr is already running map 2, since it has slip on aprokics as well.

Map 2 is designed for pipes & air filter

I've got one in my '03 600RR. Also had one in my '01 ZX6R.

On both bikes there was a noticeable improvement in throttle response. I haven't had any dyno testing done vs. the stock filter though.

I've seen tests overseas, and the DNA gave 1-2hp gain on a 929 over the stock filter.

Out of interest, that same test showed the K&N to reduce hp by a couple compared to the stock filter. As well, from looking at them, they seem like they offer a whole lot less protection than the stock or DNA.

K&N's usually have a smaller surface area than a stock filter, or most aftermarket brands. They're also at their most efficient (filtering wise) when they're a bit dirty.

better than stock. fitted one to my GS1200 SS. no problems. think they are very similar to K&N.

[ArcherWC]

Fitted one to the R1 along with cored pipes, slight gurgle on down rev, otherwise it goes hard

[Hitcher]

The FJR has a DNA filter. Over 4,000rpm it sucks like a Bangkok whore on heat. Although I have an expert opinion that a clean stock filter does the job just as well and that a K&N would be a better choice for this bike.

If you can see yourself having the bike for long enough to pay for itself in replacment filter costs then all good. If not, then I doubt you'll notice any performance difference whatsoever.
All the sports bike manufacturers are keen to quote as big a HP figure as they can and something as easy to fix as a filter is gonna be pretty high on the hitlist eh?
I've yet to see an unbiased dyno test showing an improvement that didn't include a power commander, and my money is on the PC making the improvement not the filter.
