I've gotten Daox's 3D-printed MAF and will be making my own intake. I've seen Daox's intake build where he used an AEM intake. However, I'm curious as to what others have used for a filter?
I'm pretty set on sticking with K&N, as I've used them for years on countless cars. My '07 Toyota Yaris has a K&N intake system that utilizes the RU-5174 (lhttps://www.knfilters.com/ru-5174-universal-clamp-on-air-filter), and I thought I might just go with it. I suppose it'll depend on my pipe size.
Regardless, what cone filters did you use? Bonus if you have the part numbers.
