Standard on all ROUSH vehicle packages for 2018-2023, ROUSH Hood Heat Extractors are the ultimate addition to the hood of your 2018-2023 Mustang GT or EcoBoost! Hood Heat Extractors add an aggressive touch, and are fully-functional. They are molded raw black and allow the release of heat from the engine bay. Designed with rearward-facing openings, each notch in the surface creates a small low-pressure aero zone to help release heat. ABS is lightweight, durable, heat resistant, and impact resistant. As with all ROUSH products, the Hood Heat Extractors are manufactured in-house and were designed using original manufacturer CAD data for superior quality and optimum fit. They come with the necessary hardware and instructions.
