Good To Know
Q: Does this gasket set fit supercharged 3.8L engines? A: Yes, it is compatible with supercharged and naturally aspirated 3800 Series II and III engines; verify your specific model year.
Q: Should I replace the intake manifold bolts at the same time? A: Bolts are not included, but replacing torque-to-yield bolts is recommended to ensure proper clamping force.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
