K&N 77-1570KS Performance Intake System for the 2014-2015 Jeep Cherokee 2.4L

K&N 77-1570KS Performance Intake System for the 2014-2015 Jeep Cherokee 2.4L

Reviving a famous nameplate is often a tricky thing to do. The new model has to meet a whole new set of market demands, while still paying homage to the original. So when Fiat-Chrysler rolled out the 2014-2015 Jeep Cherokee, they blended modern technology and car-like driving behavior, with some iconic characteristics of the much-loved Cherokee XJ. Like its namesake, the current Cherokee KL is just "the right size", it's a comfortable on-road "chore buddy", and the Trail Rated 2014-2015 Jeep Cherokee 2.4L 4x4 can take you places that Verizon has never even heard of.

The 184-hp 2.4L Tigershark engine also comes within 6-hp of the XJ's venerable 190-hp 4.0L straight-6. But the new motor is much lighter, and it gets way better gas mileage than the old AMC inline 6. And while 184-hp is adequate for most on/off road situations, the K&N 77-1570KS Performance Intake System can give your 2014-2015 Jeep Cherokee 2.4L faster throttle response, more horsepower, and more torque. This extra horsepower would allow your new 2014-2015 Cherokee to handily out perform its famous predecessor.

This is the basic recipe to make horsepower: In a metal cylinder, add 1-part gasoline, 14-parts air, and one big spark. When the mixture is sufficiently compressed by the piston, trigger the spark plug to ignite. The resulting explosion will force the piston back down, turning the crankshaft and ultimately, the wheels. For additional horsepower, substitute warm turbulent air for a higher volume of oxygen-rich cold air.This allows the fuel to burn more completely, which results in a more forceful detonation (i.e. extra horsepower). Serve the horsepower hot, with a generous helping of torque.

In a perfect world, that's a tongue-in-cheek description of how your engine makes power. But the reality is that most restrictive factory intake systems, like the one installed on your 2014-2015 Jeep Cherokee 2.4L, aren't capable of delivering enough air to achieve the full horsepower capability of the motor. The K&N 77-1570KS Performance Intake System on the other hand, is engineered to deliver a higher volume of horsepower-rich cold air, by straightening the airflow path, and reducing restrictions.

The K&N air intake replaces the narrow plastic intake tube with a larger K&N aluminum intake tube, which features mandrel-bent curves to provide a wider, less restricted airflow path. The silver powder coated finish not only looks great, but it provides protection for the aluminum tubing to make it easy to clean. This K&N intake tube has built-in fittings for the inlet air temperature sensor and crank case vent hose. So you can install the system in about 90 minutes, without making any additional modifications under the hood.

To feed a high volume of cold air to your 2014-2015 Jeep Cherokee 2.4L Tigershark engine, the K&N 77-Series Performance Intake System utilizes an oversized conical K&N air filter that lives behind a heat shield where the stock air box used to be. The rugged heat shield keeps warm air from entering the system, while directing a steady flow of cold air into the filter. Besides flowing considerably more air, that reusable cotton-gauze air filter cleans the air with 97-99% filtration efficiency. Removing even microscopic contaminants from the air, to keep your engine protected on the trail, or on the highway.

The large K&N conical air filters used on K&N air intake systems can also go for up to 100,000 miles before it needs to be cleaned. But if you do a lot of trail riding, or drive in dusty/dirty conditions, you'll want to inspect the air filter every 25,000 miles. Cleaning is easily performed with a readily available K&N Recharger air filter service kit.

The heavy-duty components of a K&N 77-Series Intake System were developed specifically for trucks and SUV/Off-Roading applications. So the system can withstand some serious abuse. Plus, the air filter, and the entire K&N 77-1570KS Performance Intake System is backed by a 10-Year/million mile limited warranty. So your Cherokee is guaranteed to perform better for many years.

K&N installed a K&N 77-1570KS Performance Intake System on a 2014 Jeep Cherokee 2.4L, and dyno testing revealed an estimated increase of 3.37 horsepower and 4.31 lb-ft of torque. The throttle response was also sharpened, because the additional airflow allows the engine to make more power at lower RPMs. Your individual results may vary however, based on the mileage, modifications, and condition of your specific Cherokee.

By giving you more power lower in the rev-band, the K&N 77-1570KS Performance Intake System can help your 2014-2015 Jeep Cherokee 2.4L to start becoming a legend in its own right. K&N also makes lots more performance parts for other Jeep models like the Wrangler, Grand Cherokee, or Liberty. To explore our extensive parts catalog, click here to use the Search by Vehicle Tool.
