Product Description

Fits 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
