Recommended upgrades: Select the matching X-pipe, SMG LS MLS gaskets, SMG 9070C ceramic plug wires, and O2 sensor extensions above. The ceramic plug wires resist direct header heat and are the only wires used on SMG in-house header builds because ordinary rubber boots can melt against close header tubes. O2 extensions are supplied in the quantity required for this application.
Fitment: 1997-2004 Chevrolet C5 Corvette.
