If your kit includes an oiled filter, it only requires cleaning every 100,000 miles under normal highway driving conditions (as opposed to 15,000-20,000 miles for a disposable filter), and a K&N Dryflow filter can go up to 50,000 miles before cleaning.
For v6 guys this intake gives you a sleeper status. Not as loud as most cars with a k and n but it definitely is a performance part. You will notice a faster pick up and a turbo like noise under the hood(like a spooling but it stops) . Easy to install and a great product as always from k and n. it's pricy but worth it.
