Will a K&N air filter void my Ford warranty?

I really want to put a K&N air filter on my Ford Mustang but it’s still under warranty. Will installing it void my coverage?

Installing a K&N air filter will not void your Ford warranty—and it can help to protect your engine and result in a 2-3% improvement in your car’s acceleration time! K&N actually guarantees customers that the use of their air filter system will not result in a vehicle warranty denial from your manufacturer.
This is partly the result of the Magnuson-Moss Warranty Improvement Act, which states that manufacturers cannot legally “condition a vehicle’s warranty on the use of any brand filter unless the manufacturer provides the filter free of charge or is specifically published by the Federal Trade Commission in writing that only the vehicle manufacturer brand be used.”
But while a K&N air filter won’t void your Ford’s warranty coverage, you’ll still need to invest in reliable insurance to ensure your car is fully protected. Find the best
