The K&N 69-3518TS Air Intake fits some Ford Focus ST models. See vehicle applications link for details.
The K&N 69-3518TS Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford Focus models. The restrictive factory air filter and air intake housing are replaced by the K&N Typhoon air intake which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. This allows your engine to inhale a larger amount of air than the factory air intake. More air means more usable power and acceleration throughout the engine’s RPM range. The 69-3518TS air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive silver powder-coat finish that's made to last and it accommodates the factory air pressure sensor. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. Some Typhoon air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the vehicle applications and specific CARB status for each vehicle and air intake.

K&N 69-3518TS Air Intake Product Reviews

Very easy install, sounds great, and adds a little noticible horsepower. Would reccomend it.

I see no reason why anyone with a Focus ST should not buy this intake. It was extremely easy to install, only took me about 40 minutes and makes the car sound so much better. Plus you get a little more power and I'm actually seeing an increase in fuel economy also (with sensible driving). Nothing not to love about this kit. If your on the fence and not sure if you should buy it or not, JUST BUY IT! It will not disappoint.

2015-2016 FOCUS ST Owners: Check your IAT sensor prior to ordering. Ford changed the part to a twist-in sensor on some vehicles. I discovered this 95 of the way through installing this kit. As mentioned before, K&N is working on another aluminum section to accommodate this change on certain vehicles. What makes a non-fitting intake a 5-star experience? This was my fourth K&N Typhoon kit, and only my first customer service experience. The first three were flawless (and I gather this one is too, when your vehicle has the other sensor type). When I spoke to K&N about this problem, they were quick to research it and confirm the need for a revised part on some kits, and have been fantastically responsive in our communications. It isn't easy to find a company whose team members still stand behind their products AND their customers, folks.

The intake kit did not fit my car, so I sent it back, but the people I spoke with at K&N where excellent, very helpful and when they let me know when the kit is updated to fit my car, I will reorder.

I have to say first, this kit is awesome! The sound and performance are amazing! The installation was easy and the instructions were easy to follow. I have and will continue to recommend K&N to anybody and everybody I know. Thanks again!

Fitting instructions are very clear and the actual fitting is very straightforward. The car sounds so much better than before. Would definitely recommend this kit.

First of all this was my first install on an intake and let me say it was easy I'm not mechanically smart (30), but I really shocked myself on how well it went. It took me exactly 1 hour to complete. The directions were easy to follow and the diagram was very nicely done.
