I was under the impression the F1 and F2 was superspeed by the N1. I also have a 2025 Corolla hybrid and the original filter is little longer than the N1 and always thought it was equivalent to the F1 or 2. The dealer always gave me a N1 for it.
I like the idea of it but do question if there's really something to it or is it all marketing. Seems like if there was a real need for it other manufacturers would have a similar product.
