Denso 453-6039 Premium Cabin Air Filter for Cars & Trucks - Improves Air Quality & Reduces Allergens - Perfect for Daily Commute & Road Trips

Yeah these fit perfectly.It's a "so-so" semi-easy enough job on my 2010 Mazda 3i Touring LF2.0 5 speed.I found I had to get on the garage floor with legs stretched out underneath the car towards the front. It's awkward. But they went in ok at the last second.After getting them in, and interpreting the direction you're supposed to observe ( the plastic frames of the filters have an embossed arrow), I read the instructions and it says OPPOSITE WAY! Different from what every other perfect-fit aftermarket filter says. Oh well. Saved the instructions just in case."Little" more output from AC. Maybe.
