I rate the service and customer service at 5. However, the listing and cross reference information given per the EB site is a little misleading on description. I was looking for a K&N filter for a Kohler K161T 7 hp engine. It is a 1971 vintage and though it would be a nice touch compared to a paper pleated filter. The size E4400 must fit a later model Kohler K161 instead. The filter was the right ID and OD, but simply too tall for my given air box. If it could have come in a size at a height 1.5 inches it would have probably been a go. I included the original Kohler air filter part number in the return if you have or can make one to suit. Mike

Everyone tells me K&N products are the best so I got these to replace Kohler oil filter. I was just a little disappointed because the filter end does not fit into my Kohler cap so I need to find another tool. Other than that, I think the quality of K&N is great and the price is very good too.

Exact fit replacement for the Kohler M10 HP. Of course, the quality and performance I've come to expect from K&N is there. Works great for the often dry and dusty conditions encountered in eastern Colorado.
