The EGR valve on Z32 models sends exhaust gasses to both sides of the intake manifold via a pair of tubes that wrap around each side of the engine (one tube on each side) under the intake manifold. Each tube uses a gasket at each end to seal in these gasses. This gasket seals these tubes to the EGR valve itself. Sold individually, 2 required per car (1 per side). See 10-2584 in Related Items below for the gasket that seals the tube to the intake manifolds.
