Hasnt leaked
Been using this for maybe a year now and it hasnt leaked. I didnt get this because I'm sitting and watching head temps and trying to get them controlled like i read on some other reviews. I got this because i read that the mesh did better filtering than the standard filters and it has the magnet to catch any metal floating in my oil. On that note, it does look good on the bike, doesnt leak, bike hasnt got any hotter or cooler that I can tells since i wasnt and have not been monitoring head temps, and people who notice it ask about it. Would I buy it again... YES, I would buy this again just for the possibility that it might save me in the future, it has performed as an oil filter without failure, and the many claims that it does actually help with head temp. I decent price for some piece of mind

Decent quality but didn't cool my oil temperature.
Update Feb 21 2022: I did my oil change today after 5000 miles running full synthetic and the oil magnet on the inside caught a good amount of fine metal shavings. In the picture, I wiped off a little from the magnet to get a good view of how much it caught. The oil filter seems to do it's job and I'm very satisfied with it. Original Aug 26, 2022: A decent quality reusable oil filter. 4 stars because the filter looks as though it was put together with wood glue- that part I'm not satisfied with We'll see how long that'll hold up. The oil filter comes with four items: a spare O-ring, the filter, a spring and the filter canister. Highlights: -there's a hex nut at the end of the filter to take it out with a socket. -the canister can also be removed with an oil filter cap wrench. - there's a hole at the end of the hex nut for a tie down for those who take their bikes to the track. -finned design on the canister is to "act" as an oil cooler because of better air flow around it. -the magnet seems pretty strong. It was strong enough to hold some kitchen scissors so I'm confident it'll be able to catch some small metal shavings in the oil. My observation: I'm using this on a 2017 HD Ultra Limited. I run a power vision and normally operating temperature on the highway fluctuates around 248-278 degrees in afternoon Southern California weather. But roughly 258 degrees is my constant temperature riding around on the highway. The main reason I bought this was in hopes of cooling the operating temperature down. I've researched that in the Harley Twin Cam touring models it can cool down by at least 10 degrees but for the M8 touring models it doesn't really do much for cooling down the bike. I have not seen any improvement at all for cooling down the bike and I constantly monitor my engine temp via my Power Vision tuner. The product is visibly smaller than a standard disposable oil filter. I hope that it does in fact filter better. I have noticed that the engine doesn't sound as noisy or shakey as before at idle. I don't know how much of that is from better flow/filtration from the oil filter because I also switched from being a long time Lucas full synthetic user to using Mobil 1 full synthetic for the first time on this bike. Installation was just as easy as using any other oil filter. There was no issues with any leaks. Everything seems in good order. I will definitely update once I get to my next oil change 5,000 miles from now. But so far so good. I feel like this product is worth buying. If It'll help with engine longevity that's my main goal and It'll pay itself off in about 7 oil changes- I don't plan on buying another motorcycle for a long time.

高価ながら性能的に満足。17mmで開けられ好印象。アルミ削出しボディはフィン形状、放熱良さげです。フィルターストッパーつけられる穴もあります。交換後は車両がスムースでレスポンス良く感じます。オイル流量7倍との事、エンブレが効きにくなるようなスムース感!?また紙フィルターより細かい目のステンメッシュはブレーキパーツクリーナーで簡単に清掃できました。スラッジ等の異物を目視確認できエンジンの健康状態を見れて◎。使用済エレメントのゴミ処理にも難儀していたので非常に助かります。目詰まり起こしたりする安物フィルターでエンジンを壊す事もありますので、これは個人的にかなりお気に入りです。

La presentación del filtro es de muy buena calidad, los materiales sólidos y en excelente estado, trae dentro un Magneto para las impurezas, y un sello de repuesto, lo cual se agradece, físicamente es un poco más pequeño que el original, en cuanto a funcionamiento vivo en Monterrey, la cuál es una ciudad muy caliente y note una diferencia de temperatura de aceite de aprox 9-10 grados menos, el motor se siente más silencioso supongo que por un ligero incremento en la presión de aceite, si tienes una Harley está te lo va a agradecer , es un poco caro pero vale la pena la inversión , tienes un filtro relavable que se paga por si solo, y lo mejor trae un beneficio en temperatura y filtrado , 100% recomendable!!, Ojo según la página no le queda a mi moto es una Sporster 1200 custom,2007 , sin embargo revise las especificaciones y le queda a la perfección .
