Im wondering if I have two good filters on my hands: When I bought my Honda Feb 2013, the guy gave me 2 filters that he wasnt going to need. One I recognised immediately, a Purolator classic in the box that we all currently know. The other is in a darker blue blox and is labelled Purolator Premium Plus. Ive never seen these before. From looking at these, side by side, its obvious to me that the "Premium plus" became the "classic" and im guessing they are identical internally, am I right? The filters both have the L14459, look identical apart from the slightly different print. If I need to look into it further I will translate these codes to see when they were made: the classic has F10 C07D1 manf code and the Premium plus has F02 V04D2 manf code. Am I right that these are both made before you guys started seeing tearing issues with the classics?
