Cummins 12-Valve & 24-Valve Exhaust Manifold Blanket

Turbo Performance Products pioneered vehicle-specific diesel heat blankets in 2008. This manifold blanket is designed specifically for stock and aftermarket cast 12-valve and 24-valve Cummins exhaust manifolds, including many popular three-piece designs.

Why Run a Manifold Blanket?

• Helps reduce underhood temperatures
• Retains exhaust energy to support faster spool-up
• Helps reduce heat transfer into the intake system
• Vehicle-specific fit—not a one-size-fits-all blanket
• Typically installs in less than 15 minutes
• Remains soft and pliable through repeated heat cycles
• Includes four stainless-steel installation ties

  Construction

  Built with three full material layers and a 1/2-inch silica insulation core. Rated for continuous exposure up to 1,800°F, with short-duration exposure capability up to 3,000°F.

  Proven Experience

  Made in the USA by Turbo Performance Products, the company that pioneered vehicle-specific diesel heat blankets. We’ve built more than 25,000 heat blankets since 2008 for diesel owners, professional shops, and dealers around the world.

  Fitment note: Fits stock and compatible aftermarket cast exhaust manifolds for 12-valve and 24-valve Cummins applications. Contact us before ordering if you are unsure about a particular manifold.

Unlike a universal wrap, the blanket is patterned to fit the manifold closely, install quickly, and stay securely in place. It helps retain exhaust heat inside the manifold, reducing underhood heat and supporting faster turbo response.
