Frequently Asked Questions
Does the KNN70-1563 require a tune on the 2011-2021 Jeep Grand Cherokee 5.7L Hemi?No. The KNN70-1563 is designed for plug-and-play installation with the factory ECU and all OEM sensor connectors. No tune or recalibration is required.
How much horsepower and torque does the KNN70-1563 add to the Grand Cherokee Hemi?K&N dyno testing on the 2011-2021 Jeep Grand Cherokee V8 5.7L recorded gains of up to 18.5 horsepower and 31.8 lb-ft of torque with the KNN70-1563 installed.
Does the KNN70-1563 also fit the Dodge Durango 5.7L V8?Yes. The KNN70-1563 is fitment-compatible with the 2011-2021 Dodge Durango equipped with the 5.7L V8 Hemi engine.
Will installing the KNN70-1563 void my Jeep factory warranty?Under the Magnuson-Moss Warranty Act, an aftermarket intake alone cannot void a factory warranty. The dealer must demonstrate the part caused a specific failure. K&N also provides its own limited warranty covering the intake system components.
Is the KNN70-1563 legal in California?Check K&N's website or the product packaging for the current CARB Executive Order status for your specific model year, as certification can vary within the 2011-2021 range.
What is the service interval for the filter included in the KNN70-1563 kit?Under normal highway driving conditions, K&N recommends cleaning and re-oiling every 75,000 to 100,000 miles. In dusty or off-road environments, inspect more frequently and service as needed.
Does the KNN70-1563 work with the Grand Cherokee SRT 6.4L V8?No. The KNN70-1563 is specifically calibrated for the 5.7L Hemi V8 engine. The 6.4L SRT engine requires a different intake kit designed for that application.
