Does its job
Used in my LC9 rebuild. So far works fine although engine has only ran a couple times but it makes oil pressure fine so I assume its doin its job. Fits fine in factory location, cant complain for the price

Fits Perfectly. Super snug fit. Make sure to soak it in oil b4 installing
Bought it to replace the plastic one on my 2012 4.8 Silverado. Was worried it was too big and wouldn’t fit. But it fit perfectly I soaked the rings in 10w40 and then slid them on to the plug. Super tight. Be careful not to rip it. Then soaked it all again. And when it went in it helped. I used my fingers to push it in. its super snug fit so b careful. At the end it stop an eight of an inch out and was hard so I just tapped it with a mullet and perfect fit. FLUSH FIT perfect fit. if it doesn’t work I’ll come back to change my review. So far so good.

Good
Went in a bit rough, but with some love taps and some engine oil, it went in pretty smooth. Tip: To remove the old barb, get a wood screw and drill it in, pulls it out easily

Seems well built, installed fairly easily. Haven't ran the motor yet to see if it does what it is supposed to do but definitely better than the factory plastic one
