This is the second one I purchased. Replacing the first one after three and a half years. Does a great job.

Excellent air filter for my Detroit Diesel S-60 engine. I replaced (Brand Name) air filter with this one because it is easier to clean and it gives it really good air flow, which improves throttle response, performance and fuel mileage, for a sensibile driver. The price is reasonable and the shipping was free. Good deal.

Hi: I was excited in obtaining this Air Filter as I would not need to oil this unit. That will be good to experience when the time comes. I was not prepared for the long wait for delivery. It took a few weeks for the product to be delivered. I then received a e mail that new purchases would include your K&N cap. Great So I sent an e mail to K&N for a hat. I figured if I had to wait a number of weeks for this air filter and not make a motorhome trip(old filter was sand filled), I would get a good will 'hat' for my patience. I have not received any messages of my request. So, the air filter looks solid and the size is exact. I would still like the K&N hat. Thanks, Bob Emmert
