Just completed a replacement of my two idler and one tensioner pulley(s) this weekend. There's plenty of good write ups on here for that, so I won't repeat what others have said.
I saw this turn-key fastener in a hardware store a few weeks back, and decided to give it a go to clamp to the throttle body. I'm calling it a "quick disconnect" since we're always having to remove the air filter housing to do any work. Truthfully it might save you 6 seconds, depending on how close-by your screwdriver is Thought it looked pretty cool when paired with your existing oil cap and dipstick.

Not trying to start a trend here, but if interested it's on Amazon
