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.
The whole reason for buying the 69-1008tb was to replace the factory air box which has been broken twice by mechanics that have worked on my car. After careful installation and about two weeks worth of driving, I can positively say that this was worth the purchase that will pay for itself. The best thing I've noticed within the first minute of driving was the throttle response. It makes the car so much fun to drive. I feel I'm back to when the car was first bought. I've installed it on a 2003 Honda Civic 1.7L engine. Thanks for the product.
