Query: No date at all on it. That seems shady.

Another commenter here said that they bought this from Fox Racing and the expiration date was 2005. I bought this same item from this same seller just now, and there's no date on it at all.When these are made, they have a date on them. Many online merchants remove the date - or to be fair, it may well be the merchant's supplier that removed the date. I've seen several merchants explain that they get these from so many sources that it's impossible for them to make any claims about any dates at all. Fair enough. However, if just one frickin merchant would stick to making such claims, and would sell filters that aren't expired, they would get ALL the business. (And then immediately run out of stock probably :)I'm knocking off two stars because I have to assume it's expired and thus no longer NBC protection. I'm knocking off an additional star because someone removed the date altogether.
