K&N KN-171C Motorcycle Oil Filter: High Performance for Harley Davidson & Buell Motorcycles - Compatible with Synthetic & Conventional Oils Review

Wondering how they got 1 star? Must have been a customer error, this filter fits our '01, Dyna and our '05 Softail and also our '09 Electra and 10 Street Glide. That's right, these filters don't have the same dome as other filters, though. When measured, the difference was less than three thousand, which did not matter. So the 1 star reviews I can only imagine are people not qualified to change their own oil between the cross section and maybe the old gasket left on the bike I could find out if

I bought this filter for my Fat Boy because it ended up with a 17mm hex head for easy removal and I'm glad it did I did that. When it came time to remove the stock HD filter, I didn't have the right oil filter tool. Yes, I have two filter removal tools - one that grips the can with canvas tape and one that slides on the end like a socket on a nut - but due to tight tolerances, neither will fit the Harley. The heavy duty oil filter is pressed against the engine about a quarter of an inch so…

2003 HD Road King (with oil cooler) This might be a little unfair as a rating as I haven't worn it. The reason is that it is slightly longer than a standard HD filter. I didn't know about them so I bought a pair as I had heard many good stories about K&N filters. And with a nut on the end, it's easy to unscrew. What I found on my bike (2003 Road King 88") with the radiator oil cooler adapter is that this slightly longer filter did not clean the crankshaft sensor. So I had to go with the…

I have never had a quality issue with K&N. The last time I bought it, the nut didn't end up being a specific size. I've tried every US and metric size on both sides of the advertised 17mm and none of them could grab them well enough to loosen the previously installed manual filter plus 1/4 turn of a K&N filter. I also tried different types of heads (6pt, 12pt), wrenches and whatever I could find in the allowed space. Everything will slip. I strongly suspect the nut was the right size BEFORE it…

Look I love my Harleys. These are great bikes. But I despise how Harley feels the need to rape me every time I buy parts from them. 25€ for an oil filter? Is it made in China? ok man That is not right. But I only use K&N filters in all my cars no matter what the cost. The fact that it's less than half the price is just the icing on the cake. See I took the time and researched. If you wish, go straight. You will end up in the same place as me. Only use K&N filters and Mobil 1 oil. Two cars, two…
