Product Reviews      Review part 33-2391

 It fits. What can I say. I have not driven it to check if I have more power or better fuel mileage yet. It is on my camper van which I only use for trips. I have not priced a regular paper filter so I am not even sure I will save money in the long run but I have found with my other cars that it is easier to clean a K&N filter than it is to locate a paper filter. I have a Honda Prelude and a Dodge Ram 2500 diesel and I have found that locating a filter for these can be an issue. Even the dealers don't carry filters all the time and I end up ordering one and waiting for days to get it. The K&N option is by far easier and better for me. I hope this one for my camper does as well.

 After your representative explained where to mount the air filter, it fit perfectly and am looking forward to it's performance.
