Sinister Diesel Cooling Line 3/8″ by (4ft) (SD-HOSE-3/8-4) Universal

Whether you’re replacing a worn OE hose in your truck or need an extra hose for a new modification, use this Sinister Diesel Blue Hose. It will survive high temperatures and exposure to oil, so you don’t need to worry about the hose cracking or falling apart anytime soon. What’s more, the Signature Sinister Blue finish adds a nice touch to your truck’s engine compartment, along with the white Sinister Diesel logo.

The key to the durability of this hose is the fact it’s made of 2-ply silicone that’s resistant to high temperatures and oil. You get 4 feet of 3/8-inch inner diameter hosing.
