Green Filter 7159 Green High Performance Air Filter

I drive a 2013 Ford Focus ST and it's Everything I hoped for. Had a stock filter, switched to this high performance filter and it is great. Personally, I noticed a slight increase in throttle response, and high end power. If you're looking for a power adder, this isn't the ideal product, but it does help your car breathe ALOT better. The best part about this filter is the INDUCTION NOISE AND OH MAN is it sweet. Turbo sounds come through alot clearer and louder and you get more spool noise when boost kicks in. I run this without the factory intake lid, because this filter comes with a 'O' clamp to bite onto the intake piping. With the lid, there is still noise but to maximise noise I run it without. Expectations were met and I do reccomend this filter.

I have Focus ST 2017 its fit it and turbo sound is very nice , I recommend anyone have Focus ST to buy it

This is for the fit on a Ford Focus as it fits PERFECT to the airbox yet adding that cool air effect with a open end design. You have to see if it will do the same for your Ford design air box!!! I do know, If you have a 2015 Ford Focus & simular air box ( as that design went a long want on many fords) this is a must... if you like to hear the amazing sound of that engine ( mine is a 2.0 & it works on turbo) and not go broke on a cold air intake, this is a must! It does the same thing at a third of the price of a air charger! I love it! It is very well built, I was shocked at how it is better than any other top name I have used in the past! I will be ordering more of Green Fikters to replace the air chargers on my other rides! I didn't know they could be made this well. Skip the nightmare of a whole air charging instal!!! This saves loads of money and time! I love it! ( also delete the snorkel.. find how online)

Couldn’t be more happy with this filter, it performs well I think the value for what you pay if worth it, it looks simple to clean and the way the you hear the turbo almost every time you touch that throttle I love it

Fits the ford focus ST Perfectly!
