The 3800 L67 & L32 supercharged V6 is a popular platform for performance modification

and Yella Terra manufacture supercharger power upgrades that are both effective and visually appealing.

The Yella Terra supercharger cover assembly features a billet alloy snout and new cast alloy
cover precision engineered to easily replace the factory cover. A variety of pulley diameters are
available to vary supercharger boost and these are secured to the drive by 4 cap screws to allow
quick pulley changes without specialized tools.
