The K&N 69-5301TTK is a Typhoon short ram intake built on a mandrel-bent aluminum intake tube paired with a washable, oiled cotton High-Flow filter. It replaces the factory air filter and intake tube rather than adding to them. The manufacturer lists an estimated gain of 7.75 HP at 5147 RPM and an estimated 7.9 lb-ft of torque, and the filter only requires cleaning every 100,000 miles under normal highway driving conditions. Compared with a cheaper drop-in filter, the smooth tube and sealed airflow path give you a more complete replacement of the restrictive stock box. Owners on user forums say an intake like this is a bolt-on that does not require an ECU tune, since the car's mass airflow sensor adjusts automatically. Shoppers looking for a 2011-2014 Sonata 2.4L cold air intake, a 2013-2015 Optima 2.4 short ram, or a K&N Typhoon for a 2.4 GDI should confirm the application against their VIN before buying.
For DIY installs, the manufacturer says a typical installation can be completed in 60 minutes or less with simple hand tools. Disconnect the negative battery cable first, and take care with the small plastic vent fittings, which the manufacturer's install sheets for related Typhoon kits warn can cross-thread easily. The kit carries the manufacturer's No-Hassle Lifetime Limited Warranty. Long-tail searches like "2.4 Sonata short ram intake install," "Typhoon intake 13-15 Optima," and "K&N 69 series mass airflow sensor fitment" point to the right fitment and install details for this part.
Yes. The manufacturer states the system replaces the factory air filter and intake tube, so the stock intake parts are no longer used once it is installed.
The manufacturer's product page lists a CARB EO number but also states the part is not legal for sale or use in California on any pollution-controlled motor vehicle. Confirm the current status with the manufacturer before ordering for a California vehicle.
Owners on user forums report that no ECU reflash is needed for a bolt-on intake on these engines, because the factory mass airflow sensor adjusts to the new airflow. The manufacturer does not list a tune requirement on its product page.
The manufacturer rates the install at 60 minutes or less with simple hand tools, which makes it a reasonable weekend job for a home mechanic. Start by disconnecting the negative battery cable, then remove the stock intake tube and airbox assembly. Pay close attention to the mass airflow sensor connector, which must be reconnected to the new tube. The plastic NPT vent fittings should be tightened hand-tight and then given about two turns with a wrench to avoid cross-threading. Check all five clamps and both couplers for a tight, leak-free seal before starting the engine.
