so your drawing in from the snow cowl, what's the CSA of the intake there? Cheers

I have the same Nakatanenga wingtop setup which includes the powder coated stainless steel snow cowl. I have not measured the cross sectional area afforded by the Snow cowl , noting it’s just a cover not tubular, however I would say it’s at lest 1.5 - 2 times bigger than the large bore ( circa 90mm diameter) circular hose it feeds into (which is secured to a plate that attaches to the wingtop).
Thefore this setup affords the ability to deliver far more air to the filter box than the std setup, with the limiting factor being the much larger bore circular intake hose, not the Snow cowl.

I have one of those Nakatanenga kits brand new for sale in classifieds if anyone wants. Plus another matching snow cowl for other side. WARNING.

I looked st this in detail before for my m57 intake, 100mm pipe and couldn't get dims of snow cowl openingnfornthe naked one. I presumed 40mm x 180 working off variation on other after market cowls. Csa 7200 which for 90mm pipe works fine although not quite there to 100mm pipework. Hence interested to know nak dims. Cheers
