A replacement PCV valve for my car.
Car was around 100,000 miles, figured it was a good time to do a big refresh & replace a bunch of stuff. Spark plugs, belts & hoses, fuel & air filters, fluids, etc etc... While I was at the parts store, guy suggested I also replace the PCV valve. But, it turned out the only one he had in stock was the store brand. $4, sure whatever. Got it home, took the factory one off the car, and sure enough it was gummed up kinda bad. But went to put the new one on, and it just about collapsed in my hands. It was so flimsy, kinda like a drinking straw. Ended up cleaning the factory one & putting it back on, threw the new one away.
