Does the KNN70-1576 require a tune after installation?No. The KNN70-1576 is designed for full plug-and-play installation with all factory sensors and the stock ECU. No tune or reprogramming is required.
How much power does the KNN70-1576 add to the Jeep Wrangler JL?K&N dyno testing showed gains of up to 12.5 horsepower and 13.3 lb-ft of torque on the 2018-2026 Jeep Wrangler V6 3.6L with the KNN70-1576 installed.
Will the KNN70-1576 affect the Wrangler's water-fording capability?The NextGen air box positions the filter in the stock intake location. It is important not to ford water deeper than the factory air box mounting height. As with any performance intake, the K&N warranty does not cover hydrolocking caused by water ingestion.

Is the KNN70-1576 legal in California?Check the K&N website or packaging for the current CARB Executive Order status for your specific model year. Emissions regulations can vary by vehicle year.
How is the KNN70-1576 filter cleaned and maintained?Use the K&N Recharger Kit (99-5000). Apply K&N Power Kleen cleaner, let soak for 10 minutes, rinse gently from the clean side, allow to fully air dry, then apply K&N Filter Oil sparingly and evenly. Allow oil to dry before reinstalling.
