The K&N 69-7003TTK Typhoon is a short ram intake for the Nissan Sentra 1.8L. It is built around a mandrel-bent aluminum intake tube paired with an oversized oiled cotton air filter, and it replaces the factory air filter and intake tube. A heat shield shrouds the air filter from radiant heat under the hood, and the kit uses the factory fresh air duct to help direct cooler air into the engine. Buyers searching for a 2013-2015 Sentra 1.8L short ram intake, a K&N Typhoon cold air intake, or a B17 Sentra intake upgrade will find this kit built for that engine. Its gains are modest. K&N's dyno testing estimated roughly 2.3 horsepower and 2.3 lb-ft of torque at 5255 RPM over the factory intake. Owners on user forums often debate whether a premium intake is worth its price over a stock box with a basic filter, so expect the upgrade to be about throttle response and intake sound rather than big numbers. The washable filter is what makes the price easier to justify. The filter only requires cleaning about every 100,000 miles under normal highway driving conditions.
The manufacturer states the kit maintains all the necessary factory connections. The mass air sensor is moved from the stock air box into the K&N intake tube using the provided hardware.
The manufacturer lists up to 100,000 miles between cleanings under normal highway driving. Harsher driving conditions shorten that interval.
The manufacturer's published fitment covers the 2013, 2014, and 2015 Sentra with the 1.8L engine. Confirm fitment with the manufacturer before ordering for any other model year.
The manufacturer describes a typical install as about 60 minutes with simple hand tools. Disconnect the negative battery cable first, but note that this erases pre-programmed radio memories, so write down your presets and have any anti-theft radio code ready. Install the heat shield with its stand-offs and secure it to the factory mounting points. Watch the 1/4" NPT vent fitting: the manufacturer warns that plastic NPT fittings cross-thread easily, so start it by hand and tighten only hand-tight. Keep the crankcase vent hose connected, then seat the mass air sensor onto the K&N tube with the provided hardware.
