RVNG B58 / S58 Intake Manifold Block-Off Cap is designed for builds that remove the factory EVAP lines running across the intake manifold. When those lines are deleted, this cap cleanly seals the exposed manifold port, eliminating the need for makeshift solutions. Precision-fit for OEM manifolds, it installs easily and provides a secure, leak-free seal. Compatible with B58 Gen 1, B58 Gen 2 (TU), and S58 engines.
