I love my K&N cone filter. I've been using K&N filters for over 10 years. It's always one of my 1st upgrades. My new Ford fiesta was no exception. A true gain is felt and heard. I love the sound of all that air being sucked in. If it's good enough for the pros, it's good enough for me.

I have a Ford Fiesta 2012 se sedan and I replaced the paper filter  in my Fiesta and I put the K&N drop in filter in. And man I can tell you the difference.  My acceleration is a lot better than it used to be.  My car used to jerk back from the paper filter.  once I put the K&N in  I didn't feel any jerking when I pressed the gas.  I recommmend anyone to use a K&N filter to save money in the long run if u plan to keep your car ot truck for 5 to 20 years! Also I have noticed I have gotten a increase in my MPG (depends on your driving habits). I've gotten a 1.5 to possable 2 mpg more in the city highway. I don't know yet but will keep a eye on it and see if there's a increase in highway millage. but anyways people I recommend getting a K&N filter! They're really good for your cars and trucks! They save you money!!

Yesterday, I received my order for the 57i induction kit for my 2007 1.25 Ford Fiesta. My main reason for purchasing was to improve my MPG, and even for the look in the engine bay, but what I totally underestimated was that awesome induction roar!!!

My 1.25 engine sounds like a totally new beast, and I've even noticed a slight power increase at motorway speeds.

Only took 20 minutes to fit, it looks awesome, it sounds amazing, it has superior engine protection compared to the stock airbox... simply outstanding. Well worth every penny... 10/10.
