The hardest part of changing the oil on my bike was removing the old filter. The welded nut on the top of this filter makes changing the oil a breeze and for only a couple dollars over the stock filter, not a bad price at all.
The filter looks to have a realy good chrome finish and it has the required check valve and being made by K&N I would expect nothing but the best performance. It actually seems a little redundant to put a chrome filter on my vtx 1300 since it is mounted totally under the bike and is unseeable, I figured what the heck, I know it is there.
I like the idea if the 17mm nut instead of the fluted style oil filter that is (or seems to be) the industry standard. It is a more convenient way to both install and remove old filters without special wrenches. I rated the Quality as average only because this is my first K&N oil filter and have not had a chance to see how well it performs. I have used K&N air filters in the past and if the oil filter is of equal quality I will upgrade my review to five stars.
