Will installing the KNN70-1566 void my Jeep factory warranty?Under the Magnuson-Moss Warranty Act, an aftermarket part alone cannot void a factory warranty. The dealer must prove the specific part caused the failure in question. K&N also provides its own warranty on intake components.
How is the K&N filter maintained in the KNN70-1566 kit?Use the K&N Recharger Kit (99-5000). Apply K&N Power Kleen, soak for 10 minutes, rinse gently from the clean side with low-pressure water, allow to fully air dry, then apply K&N Filter Oil lightly and evenly. Do not reinstall until completely dry.
Does the KNN70-1566 affect water fording depth on the Wrangler JK?The KNN70-1566 is installed in the stock airbox position. It is important not to ford deeper than the factory air intake height. As with any aftermarket intake, K&N's warranty does not cover damage caused by water ingestion.
