Good PCV Valve....Easy to install.
Looks like OEM and easy to install. I always use OEM but decided to try an off brand because of good reviews. Works well on a 2011 Honda Accord 2.4l. I will though change my review if it stops working before it time.

Fits our 2005 Subaru Outback
Fits our 2005 Subaru Outback. Good quality, but it doesn't feel as sturdy as the NAPA branded one that I returned because the price of this one was so much better. So far, so good.

To small
Does not fit the criteria of the current engine the screw stem is too short. Wasn’t worth it. Second thing to buy is the hose because the new metal PCV is smaller.
