I have had good luck with Napa air filters for my old Gen 2 Prius, but when I got home the ones purchased for my Gen 4, the cabin one did not fit. I have not yet bothered trying to see if the engine one fits. The part # for the cabin air filter sent to me is PFL 4234483. I just rechecked the site, and plugging in the info for my car still spits out that same part #. I also tried searching the Napa site for 87139-58010, which is the Toyota part #, got nothing. Does anyone know which (if any) is the correct part? Should I just trim to fit? It was $22 after my AAA discount. Thanks!
Let us know how it goes. I always go with Toyota OEM. Last time I got the cabin air filter for less than $20. Part # 8713976010.
I ran that part number and it does not fit a 2020 Prius. I also go OEM as well. Interestingly Toyota makes two cabin air filters, one is without carbon (just plain white) and the other has carbon. The part numbers are 87139-0R030 (non carbon) , 87139-58010 (carbon). I recently replaced the one that came with the car with the former and it fits and works well.
The pollen filter used on fourth-generation Prius and Prius Prime (Prius PHV) cars has part number 87139-28020; this part is made in Japan. Toyota dealers in the U.S. and some other countries instead sell a U.S.-made equivalent, 87139-0R030, listed in Toyota’s application chart (PDF). I’ve previously mentioned some aftermarket substitutes from Japan.
Thank you all for your replies and suggestions When I returned the filters to NAPA today, the very nice man behind the counter (Adam in Shrewsbury) ran the OEM number and found two "Enviroshield" filters that fit. Here is the part number for the charcoal one: 230322. It was $25.60. I forgot to give him my AAA number for the 10% discount, d'oh. He said this is not a search that can be done by a customer from home on the napaonline site. He was not able to locate a correctly sized engine air filter. The one that NAPA claims matches is just a little short in every dimension. I did not try to see if it would suffice. I assume leaking around the edges is not a good thing. Maybe it flattens out under the cover to fill the gaps? I don't feel like experimenting with my car to find out.
