 I was able to locate the product that I needed with a modified carb and layout for my 4x4 using your selection list, something that I was unable to do in the distant past. It has become very comprehensive. I have owned many of your filters and have never had a problem. I expect the same performance as I have come to experience. Thanks for a great product.
