Great value !
I have a 2016 Toyota Sienna , and every time i bring it in for service i am told i need a new engine and cabin air filter...i decided to buy this one for the engine filter last July...It is good quality and it took all of 1 minute to install in my car..The best part of this filter is it was less than $16.00 and the dealer was going to charge me $ 60.00 for the Toyota brand....I just put my 2nd filter in yesterday. took car in for service today and was told engine filter looks good....No more dealerships for filters...

Fits great on my 2014 Avalon 3
Fits great on my 2014 Avalon 3.5LV6. I changed filter every 20Kmiles (The first 2 Toyota filters were still looking good @20Kmiles). This GP075 filter has been in the car for 600miles. The throttle response is much better (more flow than OEM ?!). My last tank of gas shows >1MPG gain. I found myself backing off on the gas pedal quite often .. just need to reset my memory on how the car response probably. I also like how inexpensive it is ... so how do I take off a star in my rating ??? There are lots of (rubber molding) excess bits on the clean-side (none on OEM filter) ... what if one of them got sucked into the engine ???
