The Spectre 91489 Intake Tube and Duct Mounting Plate provides a secure way to mount a 4-inch inlet air filter, 4-inch intake tube, or coupler directly to a flat surface. It is designed for installation on locations such as an inner fender well or radiator support, helping route cooler outside air into the intake system for improved airflow management.
Constructed from polished aluminum, this universal mounting plate offers a durable and clean-looking solution for custom intake installations. Its 4-inch outside diameter is compatible with appropriately sized Spectre intake components and other matching aftermarket parts. The flat mounting design allows for flexible placement in a variety of automotive applications.
Installation may require drilling additional mounting holes to match the selected mounting surface. The plate measures approximately 4-3/8 inches by 4-3/8 inches overall and is intended for automotive use. Verify intake tube, air filter, and coupler compatibility before installation. The Spectre 91489 is not emissions-certified for use on vehicles requiring CARB-approved components and may require acknowledgment of applicable emissions restrictions.
