Fits perfect with my 2013 Ford Focus SE if you leave the air box lid off then it gives it a very nice enjoyable sound

Great deal for the price. Focus by wire is very noisy though.

Compre el filtro por ser lavable y a la larga me ahorraré dinero al no tener que cambiarlo por mucho tiempo, no espero aumento de potencia pero el sonido del motor si cambia ligeramente .Le quedó perfecto a mi Focus 2012 y lo cambie en menos de 5 minutos , ya veremos con el tiempo como se desempeña.

This is my third K&N filter, and about my sixth of any aftermarket oiled type. As usual, the construction of the K&N is solid, and doesn't feel like it will wear out any time soon. It sticks with the OEM filter design, capping off the air box, thereby pulling cold air from the front grille area. While open-ended options are available, and make for an awful lot more engine noise, it gets a little annoying listening to the constant hiss of the BPV in stop-and-go traffic. Fun for a day? Definitely, but I prefer the more subtle sound of the K&N, and feel it offers comparable benefits while sticking to the relative safety of Ford's stock air box design.One design element others have commented on, and I agree with, is that the cap on this is simply too thick to fit into the air box ridge appropriately. It will fit, just be ready for some trial and error. I wouldn't say you have to force it, but you definitely have to work it in a bit. Just check the end cap during install, make sure the edges of the box are lined up, and it'll be a snug fit in the end.I wouldn't expect, and haven't particularly felt, any noticeable performance benefit. Similarly, gas mileage has inched up a bit, but with the number of environmental factors involved it's hard to credit the filter for that, and I would defer to formal testing posted elsewhere. The main benefit of the K&N, as it should be sold and understood, is that it is reusable. With compatible paper filters selling at around $20, the K&N is a great deal that should last the life of the vehicle with proper care and cleaning.

Perfect fit in a 2012 Ford Focus. Over the life of the car I'm sure I will save a lot on replacing this filter.

These are great! No need to focus them, perfect for little eyes and hands. Durable and they don't feel like a toy. My 4 year old will LOVE them.

Gave it as a gift and he loves it. Great focus speed and sharpness.

This was a tight fit in my 2012 Focus, but so far no other complaints. Hopefully it lasts as long as advertised.
