The K&N 69-3513TTK is a 69 Series Typhoon intake for the 2007-2009 Ford Focus with the 2.0L L4 Duratec engine. The manufacturer describes it as an aluminum-tube system that replaces the factory air filter and intake tube, with a mandrel-bent tube in a textured black finish and an oversized filter. A heat shield and mounting bracket complete the kit, which occupies the space the stock air box used to fill.
The main case for this intake over the stock box is airflow. The manufacturer says the system is guaranteed to increase horsepower and torque, and the filter is a washable, reusable oiled cotton element, so you avoid buying replacement paper filters. Owners on user forums say that moving a filter closer to the mass airflow sensor changes fueling, and opinions on whether a tune is needed vary, so check the current recommendation with the manufacturer before you buy. Shoppers comparing a budget DIY "stealth" intake should weigh how the factory sensor is mounted, since this kit uses its own hardware to relocate the sensor into the new tube.
Searches for a 07-09 Focus 2.0L Duratec air intake, mandrel-bent aluminum intake tube, or oiled cotton cone filter for the Focus usually lead to this kit's install details, and the manufacturer's sheet covers the year-specific steps for 2009 models.
The manufacturer lists this Typhoon intake for the Ford Focus L4-2.0L from 2007 through 2009. Because emissions equipment can differ between vehicles, confirm your Focus's emissions package with the manufacturer before ordering.
Yes. The manufacturer's instructions say to turn off the ignition and disconnect the negative battery cable first. Disconnecting the battery erases stored memory settings, so write down radio presets and have the anti-theft code ready if your radio requires one.
Yes. The manufacturer describes the filter as washable and reusable oiled cotton media. K&N also offers a cleaning kit made for its oiled filters.
Per the manufacturer's install sheet, the job starts by disconnecting the negative battery cable, then removing the factory air box and mass airflow sensor and mounting the sensor into the new aluminum tube with the provided hardware. The heat shield goes in next, with edge trim applied to it, followed by the intake tube connected to the throttle body hose and secured with the supplied clamps. The sheet includes separate steps for 2008-and-earlier vehicles and 2009 models, so follow the section for your year. The manufacturer warns that skipping the instructions or using non-supplied hardware can cause problems, and it estimates installation at about 90 minutes using basic hand tools such as a ratchet set, screwdriver, and pliers.
