The K&N 69-3530TS is a 69 Series Typhoon cold air intake built around a mandrel-bent aluminum tube and an oversized oiled cotton filter. It replaces the factory air filter and intake tube. A heat shield installs into the previous air box space and adapts to the fresh air scoop. Against a stock airbox or a disposable paper-filter kit, the appeal is the reusable filter, which the manufacturer says only requires cleaning every 100,000 miles under normal highway driving conditions. The manufacturer's dyno chart for the 2011 Fiesta 1.6L shows a 3.76HP increase, so set expectations for a modest gain.
Fitment is the first thing to verify. The manufacturer's product page lists this intake for the FORD FIESTA L4-1.6L F/I, 2011-2018, while other listings show narrower year ranges, so confirm your VIN against the manufacturer's application guide before ordering. For DIY work, the manufacturer rates installation at 60-90 Minutes using a wrench, extension, flat blade screwdriver, and Allen wrench. Owners on install accounts report that removing the Air flow sensor and the vaccum connection sensor was the fiddliest part of the job. Searchers looking for a 2011 Fiesta 1.6L cold air intake, a K&N Typhoon Fiesta install, or a washable Fiesta intake filter will find the key details here.
The manufacturer lists this intake for the 1.6L L4 Ford Fiesta across a 2011-2018 range on its product page, but other sellers' listings show narrower ranges. Confirm your exact year and engine against the manufacturer's application guide before ordering.
The manufacturer lists CARB EO number D-269-65, but its pages describe street legality differently, with one stating it is not legal for highway use in states that have adopted California emission regulations. Confirm the current status with the manufacturer before purchase, especially if you live in a CARB state.
Owners on user forums report reusing the factory mass airflow sensor and vacuum lines during installation, with the sensor moved onto the new aluminum tube. Verify sensor compatibility and check for vacuum leaks after installation.
The manufacturer rates this as an easy-to-moderate install that typically takes 60 to 90 minutes with basic hand tools. Disconnect the negative battery cable first and note your radio and memory settings, because disconnecting the battery can erase them. Expect to disconnect the mass airflow sensor and vacuum connections, reattach the heat shield to the factory mounting points, and clamp the rubber coupler at the throttle body. After reassembly, start the engine and check for vacuum leaks and warning lights.
