Does anyone use the K&N (303 in my case) oil filter on their bike? I picked one up yesterday. About twice the price I have been paying for a Fram at Walmart. Honestly, the primary reason I wanted it was for the nut on the front of it, as I have a hard time using the filter wrench on the Fram ( it slips a lot) when I am trying to use the torque wrench to get the specified tightness. Is it worth the extra money, ie: is it that much better of a filter? It might be worth the money to me to not have to dick around with the filter wrench (and ppl walking past my garage are less likely to learn a highly creative filthy vocabulary), but is the filter itself worth the money? Please advise.
