The only thought I have is that it's too bad K&N hasn't gotten off their asses and designed any yet. I called their customer support number over a year ago and "put in a request". They actually said they were working on them but would be a few more months before they'd be available for purchase.Islander said:Any thoughts on the advantages [if any] of replacing the air filter with a high performance type. i.e. K&N Filtercharger ?
Sorry... I had assumed that we were talking 2nd Gen.tochatihu said:I have been using a K&N filter for the last 55k or so, in 2001 Prius. HAVE noted no magnificent differences in performance nor economy. The main thing was to not buy a lot of air filters. The engine oil analyses have been clean in silicon, so this filter is not leaking dirt.
I have seen that some new model Prius drivers are buying the available model and trimming the gasket edge to fit. Not sure I'd advise that, maybe better to wait. Or email K&N so they know that a new part is needed.
