Review on 🔌 ICT Billet LS1 LS Exhaust Manifold Plug Cap: LSX Engine Test with Dust Spill-Free Technology (Product Code: 551735) by Jesus Jenkins

Finally unpacked and installed on my LQ9 which was stored under a tarp. After removing the rusty, deformed exhaust manifolds, I saw that some of the valve stems had already developed light surface rust. This is an extremely high quality product with perfectly fitting o-rings and the bolts supplied were of a better quality than those used by GM. Reassure me, I no longer worry about moisture getting into the bottle through an open valve. Thank you seller for keeping this item in stock.
