Rated 5 out of 5 by from Just what I wanted This is the only "mod" on my 2014 ST. Installation was easy but the oil on the hose clamp refused to properly clamp without slipping off. So I snugged it down a bit, and luckily it fits into the right side of the box like the stock filter so it's held in from there too. Initial startup and the first few minutes you can hear a little more hiss when changing gears. There isn't much noticible noise/sound while cruising, maybe only a tiny bit.

Rated 5 out of 5 by from Suitable for NA engine? My Ford Focus 2013 2.0litter NA engine can use it?

Rated 5 out of 5 by from Good Quality Installed this a couple of weeks ago in my 2018 Focus ST. So far no complaints. The install was easy, although a little pressure was needed to keep a good seal while tightening the clamp. It's a tight fit so ensure the bottom of the edge sits behind the lip on the far right before putting the lid back on. Not much noise difference using the stock airbox (closed) on the Focus ST.

Rated 4 out of 5 by from Recommend this It is a great product, fits perfect, has a good sound. You can kind of feel the car pulls a little bit more at the full throttle (or high rev only). But it certainly reduces your MPG (for me, down from 22.6 to 19.2, average). I believe it is because the car can take more and colder air in, so the ECU injects more fuel.

Rated 5 out of 5 by from Exactly what I was looking for I bought this about 2 weeks ago now. It's an easy install filter it fits right in your stock air box. I noticed a difference in the sound right away. It is definitely throatier. I also have a turbosmart blow off valve and it has made that puppy PSSH! Louder than before. Great easy add-on to my 2016 FoST

I don't have any performance parts in my focus st . if i only change my air filter will i notice a difference in performance an sounds of my engine?

Asked by: Nicholas
There may be a slight increase in performance, you will notice a sound difference.I would suggest a complete cold air intake.

If j get this intake with no access port will cause me to run to lean and have engine and fuel problems

Asked by: Johnb8399
The air filter alone shouldn't cause any issues.

Will this fit my 2016 focus SE Without any additional hardware?  Will this void my factory warranty? 

Asked by: 2016 Focus SE
Pop your hood and look if it is the same filter setup. This airbox and filter very likely only pertain to the 2.0L Ecoboost. I don't believe the SE has that option and likely has a regular plate filter not a round one like this.
