🔧 K&N Cold Air Intake Kit for 2012-2018 Ford Focus, 2.0L L4: High Performance, Increased Horsepower – Compatible, 69-3517TS Review

Relatively easy to install, just be careful not to over tighten the filter and damage the flimsy Maf housing. I had to reinforce the Quicksteel. The engine revs a little more freely and the sound sounds like music to my ears. There are even several independent dynamometer tests online that show significant performance gains that may be unusual for these cai sets. One of the few kits I've found that replaces the knurled throttle tube with a plain one.

I don't usually take the time to write reviews. But when something really impresses me, I have to talk about it. This set is just amazing. Direct installation. The fit was almost perfect. And all the equipment was there. The increase in performance was incredible! Gasoline consumption has increased significantly. And above 3500 rpm there is a noticeable increase in performance. In addition, the engine now emits a pleasant rally car hum. I love it. And couldn't be happier! For those worried that

If you like quiet, don't read any further. although a cruising speed of 70mph is fine as long as you don't want to accelerate. There's a weird set of new sounds that definitely sound faster and sometimes louder than my ST. Now it's more of a boxer engine, mostly at low revs with full throttle. A significant improvement in fuel economy on the highway. I've seen 43+ with about 70. I'm not sure about the city. I will update after more kilometers in a while. The assembly took about 3 hours if you…

Bought for Ford Focus 2012. Work has already been done on the gearbox recall. I installed mine without knowing CAI in about 2 hours. I used the k&n part number site as my route. Make sure the EVAP port is on top and facing the windshield. I noticed that when I tried to connect my tube the end of my tube was pointing backwards and the hose was kinked. Urban mileage actually feels a bit worse as it seems to focus on acceleration performance. So increasing the number of stops decreases the mileage

Factory air box removal went great, installation went great, it was my first time installing CAI, I read the instructions, it wasn't very clear which bushings to use and where, it was difficult to see photos in detail, if they assign a number to each part/screw and name them that, it would be better. Although that's not exactly what I'm aiming for. My problem with this unit, after installing all the hardware, I put the air filter in place and tightened the clamp and I heard a popping noise…

I installed this in my 2012 Ford Focus Titanium mainly because I wanted more power. (I wanted a Focus ST, but my wife "can't drive a stick", that's the closest thing to a Focus). It makes a HUGE difference in sound. He whistles and growls; literally. Under the hood, the car sounded like a race car. When starting up to approx. 3500 rpm and when pressing, the noise is very hoarse and you can hear the filter whistling when the air is sucked in. Very cool. Installation was pretty easy. The only…
