So it's not a ring anymore. Can I just glue the two ends back together and stick it in there, or do I really need to get a new one? If so, does anybody have the P/N? I'm guessing I've been running with a broken o-ring for the past while, since it didn't feel like I broke it when I pulled it out; who knows?

Thanks.

Get a new one from the stealership. Not much $.

it probably got pinched last time you reconnected your maf. It happened to me a while back.

I went ahead and replaced it with the OEM paper filter I bought since I had already bought it, but I should keep the K&N and put it back in next time, right?

They will likely shorten the lifetime of your MAF sensor. Stick with the paper filter

If things are a little too tight when trying to install O-rings etc., then sometimes a tiny bit of dishwashing liquid soap works - just enough to get the part installed. Learned it from my dad. Sometimes grease is used, but when grease is not to be used, then the small amount of liquid soap may help.

Thanks, will try to remember that for next time.

One other small comment - the first time I reconnected the MAF housing to the air filter housing, I just put the large O-ring on the MAF housing, and tried to connect the parts. I then saw that the air cleaner housing has a little channel with little tabs for the O-ring, and the connection was easier.
