I have a TRD panel air filter in my Sera but although I can tell you it's better than a standard item I'm not really sure how! There's lots of writing (in Japanese) on the box around two performance comparison graphs but I couldn't work out what it was all about, I think it free's up the cars breathing higher up the rev range. It's not noisy though.

Anyone read Kanji?
