The K&N 69-2553TTK Typhoon is a cold air intake for the supercharged 6.2L Hemi V8 in the Dodge Challenger SRT Hellcat. It replaces the factory air filter and intake tube with a mandrel-bent aluminum tube and an oversized, washable oiled cotton filter. The manufacturer describes an estimated 23.59 horsepower gain at the rear wheels, and its own dyno comparison on a 2017 Charger Hellcat showed a rise from 621.05 to 644.64 hp. Compared with a cheaper universal intake, this kit is built around the Hellcat's airflow and sensor fittings and is designed to last through many cleanings, not replaced every few oil changes. Owners on user forums mostly describe a louder supercharger whine and sharper throttle response, while some report smaller gains than the manufacturer's estimate.
Shoppers searching for a 2017 Hellcat Challenger cold air intake, a K&N Typhoon for the 6.2L supercharged Hemi, or a reusable oiled cotton filter for a supercharged muscle car will find this kit covers those needs. The manufacturer's product listing shows Hellcat applications from 2017 to 2023, while other fitment listings are narrower, so confirm your exact model year and trim before ordering. Most of the work is a bolt-on exchange using the factory mounting points. Expect a typical install of roughly 60 to 90 minutes with basic hand tools. Keep the intake tube's factory sensor and crankcase vent connections in mind during fitting. Full install notes are below.
The manufacturer's product listing covers 2017 through 2023 Dodge Challenger Hellcat applications with the 6.2L supercharged V8, and its blog names the 2017 Challenger and Charger SRT Hellcat. Other sellers' fitment data is narrower, so confirm your exact year and trim with the manufacturer before ordering.
The manufacturer says the oversized filter can go up to 100,000 miles before cleaning, depending on driving conditions. It recommends its 99-5000 Recharger kit to clean and re-oil the filter at that interval.
The manufacturer's estimate is 23.59 horsepower, based on its own dyno testing. Owners on user forums report a stronger supercharger whine and better throttle response, but some say gains are modest and that sound was their main reason for buying. Results vary by car and setup.
The manufacturer states that a typical installation takes 60 minutes or less using simple hand tools, and its blog cites as little as 90 minutes. All components needed for the install come in the box. Start by removing the factory intake tube and air box, then transfer the intake tube's factory intake air temperature sensor and crankcase vent fittings to the new tube. Owners on user forums suggest checking the PCV hose routing on later Hellcats, since some connect to the factory lid. Oil the reusable filter before installing it, and check all clamps and couplers for a tight seal before you start the car.
