Worked great, would buy again!
Installed in my 2014 4Runner SR5 fairly easy, it was a little stubborn at first threading it in place as I do that by hand until I get several threads engaged so I know I’m not cross threading. After that it went in just fine.

Fits. Very easy install if doing on an FJ Cruiser
Got a message from the dealership - "Time to get your PCV Valve Checked/Replaced!" Looked up the cost... too much. Look up the difficulty... very easy. Bought this, grabbed a socket set and pair of pliers (and a beer!). 5 minutes later, new PCV valve in my FJ Cruiser. Saved like $150 or something stupid, compared to dealer expense... This one is a no brainer, too easy to not do yourself, if you own an FJ. So far no problems with the car and all seems OK from OBD scan so I assume its all good. P.S. - I checked the old one ( I guess if it "rattles" that means it is working ok) and with 125k miles, it sounds just like the new one. So I probably didn't even need to do this... but I'll just chalk it up to good preventative maintenance.

Comparing this valve with the valve taken directly out of my 4Runner, they look and feel identical and have identical markings. Even comes in Toyota packaging (though that’s easier to fake). Definitely recommend this if getting to an actual dealership is difficult for someone.
