Installing a New Intake in a Dodge Challenger
By Larry Walton
Seeing the rebirth of the American muscle car has been a cool thing, especially because the manufacturers picked up some important style cues from back in the day. When Chevy styled the new Camaro after the 1968 version, they really caught my attention, and Ford did a great job on the new Mustang. Best of all these machines are real performers that can even go around a corner.
The Mopar guys also got their wish list in duplicate with the new Dodge Charger and Dodge Challenger. Almost synonymous with American muscle is the drive to make them faster, and the new technology built into these machines makes them well suited for aftermarket upgrades.
When Performance expert James McCoy at Garage 808 talks to a client about what they want to achieve with their new-generation muscle car, his first questions is, “How much do you want to spend?” Entry level modifications on a stock car cost a couple of thousand dollars to get the first tier of bolt-ons, starting with aftermarket intake, exhaust and a tune (including the necessary software, which can be used in conjunction with all of the future mods as you build the car). On one of the new-gen muscle cars these initial mods should get you about 25 additional wheel horsepower as measured on a chassis dyno.
The next step up would be a super charger, which is more common for the muscle car crowd than turbo chargers. The aftermarket is building some pretty cool super charger kits, which are relatively simple installations. This would get you an additional 75 horsepower for a total gain of 100hp over stock.
If you are going to do some of the work yourself, it’s a good idea to start with a high-flow intake kit. You won’t see significant power gains with this first upgrade, but it’s the necessary first step that makes power gains possible for further projects.
Here’s how the guys at Garage 808 installed K&N’s AirCharger High-Flow Intake Kit on one of the coolest new muscle cars, the 2015 Dodge Challenger.
The stock intake box is mostly enclosed, which is different from the K&N kit that uses a heat shield to create a partition in the corner of the engine bay.
The K&N Kit requires some assembly, but it comes with everything needed for installation. The cone-style air filter is in the box.
After disconnecting the ground cable from the negative battery post, our mechanic Tim disconnected the temperature wires.
He then removed the driver side ignition coil cover, which pops off by lifting.
Next step is to disconnect the crank case vent hose from the valve cover.
