Bought a BSR Optiflow kit, as the kit isn't that expensive (143 USD converted, as I live in the Netherlands). Build quality is good, fitment 99% and comes with a blue filter which color matches with some silicone hoses in my engine bay. But I opted to use another filter which has a massive velocity stack which should be better.
Enough talk, more pictures!
