Description

The HPS Performance black high-temperature radiator hose kit is engineered to replace the stock OEM rubber coolant hoses on 2003-2004 Ford Mustang SVT Cobra 4.6L V8 Supercharged vehicles. Constructed with a 3-ply reinforced silicone design, this hose kit meets or exceeds OE specifications and is rated for extreme temperatures up to 350F, ensuring reliable performance under prolonged exposure to under-hood and coolant heat. It actively prevents and fixes common coolant leaking and engine overheating problems that arise from cracked, damaged, or collapsed OEM rubber hoses. The package includes 100 percent stainless steel, industrial-grade embossed hose clamps designed not to cut through the silicone, facilitating easy installation and a secure seal. HPS Performance backs this silicone hose kit with a limited lifetime warranty, underscoring its commitment to long-lasting quality and customer satisfaction.
