Give Your Dodge Hellcat More Teeth by Adding an Estimated 23 HP with a K&N Air Intake Kit

Add an estimated 23 HP to your Hellcat Charger or Challenger in an hour and a half

If you own a 2017 Dodge Charger SRT Hellcat and Challenger SRT Hellcat you already know that either version will outperform every single Muscle Car built in the 1960s. But of course, despite the fact that the Hellcats generate 707 horsepower, there's always an interest in adding more. That's why K&N developed the 69-2553TTK Typhoon air intake system that adds an estimated 23.59 horsepower at the rear wheels.

The 6.2L Hemi is a completely redesigned engine. Although the combustion chamber is not a pure hemisphere, due to a better understanding of intake and exhaust airflow, as well as the addition of a second spark plug, it most definitely deserves to wear the Hemi name. In fact, in NHRA Top Fuel racing the Generation II 426ci Hemi design that powers those 300 mph missiles features a similar combustion chamber shape and dual spark plugs.

For the Hellcat (named after the WWII-era Grumman F6F Hellcat fighter aircraft), SRT developed a unique version of the Generation III Hemi engine. It features the same 103.9 mm bore as the 6.4L 392ci Hemi and an induction-hardened forged-steel crankshaft that determines the 90.9 mm stroke, for a total displacement of 6.2L.

The Typhoon Air Intake Kit also accommodates the engine’s factory emissions control devices

The block has been modified for heavy-duty use. The 9.5:1 compression ratio is reflective of the supercharged intake system, which is comprised of a 2.4L twin-screw IHI supercharger with integrated air-liquid intercoolers that can move 1,060 cubic feet of air per minute. In other words, it can suck all the air out of 10'x12'x9' room in one minute. Each Supercharged 6.2L V-8 receives a 42-minute dyno run at a maximum of 5200 rpm at 90% load before it's installed in an SRT Hellcat.

Cool air makes more power than hot air. So does increased air flow. The key is to draw larger volumes of fresh, clean air directly from outside the vehicle, and then isolate it from high underhood temperatures. With the K&N 69-2553TTK Typhoon air intake system, intake air first enters a 7.5-inch high-flow air filter sited within a heat shield that's installed into the original air box location.

The heat shield isolates the filter from underhood heat, allowing only cold air to flow to the motor

Much of the horsepower gain can be attributed to the RF-1041 oversized conical air filter manufactured from multiple layers of oiled cotton filter media -- which offers less resistance than traditional paper filters. The multi-layered red cotton material utilizes three scientific principles to effectively trap harmful dirt and dust. One is interception, another is impaction, and the third is diffusion. You can learn more about these principles in Filtration 101.

The performance of each filter design is verified through K&N's in-house testing lab, which adheres to ISO 5011 standards, ensuring that your K&N filter provides high airflow without putting engine protection at risk.

The filtered air is then directed through a black powdercoated mandrel bent aluminum tube into the engine's throttle body. The intake tube includes fittings for the factory intake air temperature sensor and crank case vent hose.

Dynamometer testing verified an increase from 621.05 horsepower to 644.64 horsepower, as measured at the drive wheels, on the same 2017 Dodge Charger Hellcat on the same day, with the only change being the installation of a K&N 69-2553TTK Typhoon air intake system.

Best of all, the K&N 69-2553TTK cold air intake can be installed in 90 minutes or less with simple hand tools.

The K&N air filter can be used for up to 100,000 miles before cleaning, depending on conditions

And once you've installed your K&N intake you've eliminated the need to buy another air filter for the life of your covered 2017 Charger or Challenger SRT Hellcat. The only maintenance required is a simple service you can do yourself.

At intervals of around 100,000 miles (depending upon your driving conditions) use the K&N 99-5000 Recharger Kit to clean and refresh your Typhoon air intake air filter, preparing it for another 100,000 miles of driving.

The K&N air filter you purchase is designed to last for the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement.

The K&N 69-2553TTK is designed to fit the following vehicles:

2017 DODGE CHARGER 6.2L V8 Fuel Injection - All Models
2017 DODGE CHALLENGER 6.2L V8 Fuel Injection - All Models
