Review ARCBOXLLC Intake Manifold Block off Plate 3-pack

The ARCBOX LLC IBOP001 Intake Manifold Block-Off Plate 3-Pack is an essential accessory for any engine builder or automotive enthusiast working on a carbureted engine. These block-off plates are designed to replace the unused intake ports on an engine when converting it to fuel injection or when performing other engine modifications.

Each plate in this set is meticulously crafted from high-quality aluminum, ensuring a perfect fit and excellent durability. The plates feature a smooth, polished finish on the side that will be visible once installed, providing a clean and professional appearance. The opposite side is left unfinished, allowing for easy identification of the top and bottom of the plate during installation.

Measuring 4.8 inches by 4.8 inches, these plates are designed to fit most intake manifolds with standard-sized intake ports. The holes in the plates are precision-drilled to match the factory intake ports, ensuring a secure and leak-free seal. The edges of the plates are also beveled, making them easy to install and reducing the risk of damaging the intake manifold or gaskets during installation.

Installing these block-off plates is a straightforward process. Simply remove the old intake port gasket, clean the surface, and apply a thin layer of sealant to the edges of the plate. Then, press the plate into place and torque the bolts to the recommended specification.

This 3-pack of intake manifold block-off plates is an excellent value, providing enough plates to cover three intake ports. Each plate comes individually packaged to ensure they arrive in perfect condition. Additionally, ARCBOX LLC offers a satisfaction guarantee, ensuring that you are completely happy with your purchase.
