### ⭐⭐⭐⭐⭐ Fits Perfectly. Super snug fit. Make sure to soak it in oil b4 installing
*by F***O on December 14, 2025*

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.
