4in Duct Mounting Plate Plastic

The 4in Duct Mounting Plate Plastic by SPECTRE is a bolt-in intake tube mounting solution designed for air intake system installations on vehicles requiring secure, vibration-resistant fastening. This component serves as the structural foundation for 4-inch outer diameter intake ducts, providing a stable connection point between the intake tube and the engine bay or chassis. Whether you're upgrading an existing intake system, repairing a damaged mount, or building a custom air intake setup, this plastic mounting plate delivers dependable performance at a fraction of the cost of aluminum alternatives.

Engineered from durable plastic composite material, the 4in Duct Mounting Plate features a bolt-in design that allows for straightforward installation without specialized tools or welding. The plate's reinforced construction resists vibration-induced loosening and thermal stress common in engine compartments, while its black finish provides corrosion resistance and a clean aesthetic. With dimensions of 5.1 x 1.25 x 5.9 inches and weighing only 0.15 lbs, this mounting plate offers a lightweight solution that minimizes added mass while maintaining structural integrity for repeated engine cycles and temperature fluctuations.

Mechanics, performance enthusiasts, and DIY builders favor this SPECTRE mounting plate for cold air intake installations, custom intake fabrication, and engine bay modifications. The bolt-in mounting design is compatible with standard fastening hardware and works seamlessly with 4-inch OD intake tubes, making it an ideal drop-in replacement for factory or aftermarket systems. Installation simply requires aligning the plate with mounting locations on the engine block or intake manifold, inserting bolts through the pre-drilled holes, and tightening to specification—a process that typically takes minutes and requires no special certification or equipment.
