Mid-Rise Plenum Base Adapter Kit - GM LS1/LS2/LS6 - Black

For use with LS Dual Plane Mid-Rise intake manifold base to adapt to modular tops.

NOTES: Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold.

Very nice turtleneck
I bought this for my husband as a Christmas present. He loves it! He says it fits well, not to heavy and is very comfortable.

Stain on collar
I was disappointed to see this stain on the collar. The fit is great & feels heavy & well made. Not sure why it would be packaged with a stain on it & since it’s white it’s even more noticeable

Material and stitching so it doesn't look cheap.
Good quality for the price. Not wool. It meets my needs. I don't wear sweaters that often so buying a pricey one makes no sense. These look great when they are new.
