Perfect OEM fit
Great OEM fit for my 2010 Chevy Tahoe Z71. Easy to install in 5 minutes. Very good quality and price. Definitely would recommend for replacement of cracked or damaged parts.

Perfect for nnbs manifold
Perfect for nnbs manifold, has slight play but the o-ring is doing its job, the elbow fitting is the important part, I just cut half the line to run to a catch can, just slip a hose over it.
