    Comments about K&N Replacement Air Filter:

    Filter went into 08 Mustang Bullitt which comes with cold air intake from factory. Have used K&N air and oil filters for years. If you have cars you want to protect, spending a little extra for K&N is worth it. Also, if you clean a K&N air filter from time to time it will last the life of most cars. So you pay a little extra but don't have to replace paper filters every 5,000 to 10,000 miles. It's also easy to order through Advance Auto's online service so even if your local store does not normally stock the K&N you need you can still get it fast
