Add an Estimated 11 Horsepower to Your 2017 Hyundai Elantra Sport 1.6L Turbo

The installation of the AEM 21-817C cold air intake kit adds a professional touch under the hood

If you’ve already purchased a 2017 Hyundai Elantra Sport, or are planning to do so, then you’re likely aware that the approximately $4,000 premium over the standard Elantra was money well-spent. For example, at that price, you probably purchased the seven-speed dual-clutch automatic – or saved about a grand and got a slick-shifting six-speed manual.

In addition, the Sport’s 1.6-liter turbocharged four-cylinder makes 54 more horsepower than the standard model, and a modern multilink rear suspension replaces the old-fashioned torsion-beam axle used in other versions of the Elantra. The front brakes are upgraded to 12-inch diameter rotors, and it comes with exclusive 18-inch wheels with performance all-season tires all the way around.

The performance hub around which all these goodies revolve is the engine: Hyundai’s G4FJ. It’s an upgraded version of Hyundai’s 1.6L all-aluminum Gamma GDi engine, but with a twin-scroll turbocharger, air-to-air intercooler, direct fuel injection system, and dual CVVT valve operation all added that make the difference.

That difference propels the Sport to a 0-60 dash in about 6.3 seconds, which was muscle car category not too long ago. And while no one is about to complain about 201 horsepower under the hood, why not add more with an AEM 21-817C cold air intake, designed to deliver an estimated 11 incremental at-the-wheel horsepower. The cool part is that those 11 ponies can be unleashed in about an hour using just a few common hand tools.

The results of AEM testing are that a stock 2017 Hyundai Elantra Sport 1.6 turbo generated 163 horsepower and 171 ft-lb of torque on the chassis dynamometer. With the AEM 21-817C bolted to the test vehicle, power jumped to 174 hp at 5400 rpm and 182 ft-lb of torque at 5400 rpm, as measured at the drive wheels.

The air intake system ingeniously capitalizes on the large, direct-flowing OEM intake duct so only cold, fresh, outside air can reach the air filter. Cooler air is denser, carrying additional oxygen to which your engine, where the computer, in turn, adds more fuel, the trick in making more horsepower.

The centerpiece of the AEM 21-817C air intake system is a seven-inch non-woven synthetic filter media, which is a highly-efficient modern material. The filter is mounted low and to the front of the car where it can take full advantage of the fresh incoming air as well as being sited far from power-robbing engine heat.

The complete air intake system consists of the AEM 21-2157DK low restriction air filter, high-quality mandrel-bent aluminum tubing, and all hardware required for the installation. The kit also accommodates all factory emissions and vacuum lines. OEM mounting brackets are utilized to allow for quick and easy installation, and the kit requires no drilling to install.

No need to service your filter until about 100,000 miles (depending on your driving conditions) with an application of AEM 1-1000 synthetic air filter cleaner that loosens and dissolves dirt and grime build up on synthetic filters so they can be rinsed clean with water. Then just allow the filter to dry in the sun, and when no longer damp, can be installed on the car and ready for another 100,000 miles of driving.
