Item looks great to say the least. The filter was an amazingly perfect fit for my vehicle. I drive a 2012 Ford Focus 2.0l and it changed out with the old stock filter in literally seconds. No having to wiggle it to fit and literally slid on the intake like butter. Tighten down the flat head bolt to hold it on tight and you're good to go! Great product!!

Best Filter Product Out There

This filter sounds fantastic, fits in the stock airbox iwth the cover on or off, and isn't terribly expensive. I really enjoy hearing the turbo spool and blowoff through the new filter. Others online have said they've experienced marginally better fuel economy but its too early to say for me. If it is true, its another added bonus.

Car Sounds Better Than Ever

Car can breathe! No but it really can now, the old paper filter is terrible. Replaced it with this one on my 2014 Ford Focus st and car even sounds better now. Can actually hear the intake induction sounds etc a lot more. You can also clean and re oil the filter to use it over and over. What a great bargain for a reusable filter.
