Product Description
For All Post-1986 Mercruiser GM V8
-4 inch Elbow
-No Spacer
In the V8 GM Small Block, GLM's fully tuned
design guides exhaust gases directly to
the riser without turbulance and back pressure.
This increases the engine's performance by 10%.
These GLM manifolds also feature an additional 40%
increase in water cooling area that decreases the
manifold's overall body temperature significantly.
In GLM's Mercruiser replacement 4 inch riser, there are two
additional water jackets. This allows a higher volume of water
to flow through the riser, keeping the engine cooler.
*All manifolds and risers are powdercoated black for maximum corrosion protection*
**Cast Iron manifolds and risers come with a 3 year warranty**
