Radiator Shroud 22in W x 19in H x 3in Deep

The DOMINATOR RACE PRODUCTS Radiator Shroud 22in W x 19in H x 3in Deep (SKU DOM545, Part Number 545-BK) is a universal-fit cooling system component engineered to improve engine bay airflow and thermal management. This cut-to-fit plastic shroud redirects ambient air directly across the radiator core, reducing coolant temperatures during sustained high-performance operation—critical for engines running extended throttle cycles or operating in hot-weather conditions.

At 22 inches wide by 19 inches tall with a 3-inch depth profile, the shroud occupies minimal engine bay real estate while maximizing ducting efficiency. The black polymer construction resists heat cycling and corrosion, eliminating the maintenance concerns associated with metal shrouds in salt-air or high-humidity environments. Weighing only 2.7 pounds, it adds negligible mass while delivering measurable thermal benefits. The universal design accommodates custom mounting configurations, allowing installers to adapt it to various radiator sizes and radiator positions through trimming and repositioning.

This shroud addresses a common cooling challenge: factory shrouds are often optimized for baseline power outputs and stock engine operating temperatures. Vehicles running carbureted or fuel-injected high-output engines, turbocharged setups, or those operating in consistently warm climates frequently exceed factory coolant temperature thresholds. A quality radiator shroud like the DOMINATOR 545-BK helps restore margin, pulling cooler ambient air and increasing radiator effectiveness without replacing the radiator itself.

The cut-to-fit design means no one shroud fits every application identically—that flexibility is intentional, allowing technicians to dial in the exact dimensions their specific engine bay requires. Installation requires basic hand tools and moderate fabrication confidence; the trade-off is a shroud precisely matched to your cooling system rather than a generic compromise.
