Thanks for the interest. Sorry this was not shown on the video but the AFR was the same for both filters to make it a fair test with no other variables. Kind regards P3

@@P3TuningLTD Very interesting, which specific filters from DNA and MWR did you use? Do you have custom or stock stacks mounted? I got interested in such comparisons recently as I just stumbled once on a "performance improvement" that actually made things worse ;-) I guess there is a lot of money spent on minuscule changes that actually don't really matter. I thought of buying a MWR filter, but now I'm not sure anymore.

@@blackmav5 yeah upgrades can be a complete unknown and getting genuine back to back tests is tricky. For this it was the MWR “R” race filter and the normal DNA air filter. (DNA actually don’t sell their proper competition filters outside of race teams or trusted sellers) with stock stacks. Ok there is a lot to be aware of when it comes to tuning mods, specifically what is the gain? Maximum power usually means revs and all the power is at the top, torque and midrange performance are actually requiring different things, meaning getting high efficiency at the top (short intake system stacks etc, short exhaust with large diameter pipes, aggressive cam profiles) kills low down performance where long intake systems, narrower exhaust and less cam profile are needed. We see lots of “bought this ex race part and now it doesn’t run well” it’s all down to what they are designed for and the other systems required to get the best from each. Most modifications actually don’t work well alone especially things that affect the engine as you have to factor getting the bike mapped to suit . Hope this makes sense and apologies for the essay. Kind regards P3 Tuning

@@P3TuningLTD Love the essay, always good to get more thoughts in. I totally agree. As rather slow driver I'd profit far more from more mid range gains instead of only high rev power. Which of course is unfortunate since I'm a Kawasaki fanboy and they don't really do mid range ;-) Hope to see more ZX-10R stuff and comparisons, just subed. Cheers Adrian
