Took me less than 10 minute to do both of them! Used the Fram from Amazon with Subscribe&Save. Only if I could set the frequency to two year instead of 6 months, I will not have to cancel it. Quality of both the filters was as good as the original that I replaced. I did not think the filters were that dirty in two years but Acura calls for replacement so I did it. Dealer wanted about $150 and made me sign "refused to replace filters" on the service order! Honda has come a long way in terms of location of the cabin air filter! 99 Odyssey needs a Dremel tool to swap the cabin filter first time you do it and takes couple of hours! Next time, I could do the Acura cabin filter under 90 seconds if I time it.
