Cold Air Box w/Hood Gasket

The Cold Air Box with Hood Gasket from DOMINATOR RACE PRODUCTS is a critical engine intake modification designed for enthusiasts and professional mechanics seeking measurable performance gains. This system functions as an isolated air intake chamber, drawing cooler, denser air from outside the engine bay while sealing against underhood heat that typically degrades combustion efficiency. Built for street and strip applications, the cold air box with hood gasket combination delivers improved volumetric efficiency by maintaining lower intake air temperatures—a fundamental principle that every high-performance engine builder understands translates directly to horsepower and torque gains.

The integrated hood gasket plays a vital thermal barrier role that's often overlooked in basic intake upgrades. By sealing the air intake path from the underhood environment, the hood gasket prevents hot air recirculation—a common issue that undermines cold air box effectiveness. The assembly measures 20 x 4.75 x 20.5 inches and weighs 3.7 lbs, engineered for compact installation without sacrificing chamber volume or airflow dynamics. The design isolates the intake filter from radiator heat, transmission coolers, and exhaust manifold radiation, maintaining consistent air density across varying load conditions and ambient temperatures.

This cold air box with hood gasket combination works best on naturally aspirated and boosted applications where intake air temperature directly impacts fuel mapping and knock detection thresholds. Mechanics installing this system should verify hood clearance and bundle routing to avoid heat soak from adjacent components. The gasket creates a seal that maximizes the temperature differential between outside ambient air and the intake chamber, making it particularly effective on vehicles with aggressive engine tunes, turbo conversions, or supercharger packages where intake charge air density becomes a limiting factor in safe power delivery.
