Specs & Features

• Volcanic Armor: Constructed with an outer shell of Fragmentized Fire Retardant Volcanic Rock, rated to withstand a scorching 1500°F Direct Heat and 1800°F Radiant Heat.
• Faster Spool Up: By trapping heat inside the turbine housing, exhaust gas velocity increases, improving Turbo Acceleration and helping you hit peak torque quicker.
• Two Finishes, One Performance: Available in a raw Standard Finish or a stealthy Black Lava Finish to perfectly match your engine bay's color scheme.
• Internal Insulation: Features a high-temp Calcium Magnesium Silicate Wool inner layer that can withstand peak temperature spikes up to 2300°F.
• Stop Heat Soak: Acts as a thermal barrier to protect sensitive engine components (hoses, wiring, painted surfaces) from the extreme heat radiating off the hot side of the turbo.
• Efficiency Boost: Improved thermal containment means hotter, less dense exhaust gases exit the system faster, reducing backpressure and increasing overall system efficiency.

Product Description

A turbocharger is basically a flamethrower living inside your engine bay. While that heat is necessary to spin the turbine, it wreaks havoc on everything around it. The COBB Tuning Turbo Blanket is the solution. Think of it as a high-tech sweater for your turbo. By wrapping the turbine housing in this heavy-duty thermal shield, you stop that radiant heat from soaking into your intercooler piping, melting your wiring harnesses, or blistering the paint on your hood.

This isn't just a safety shield; it is a legitimate performance part. Thermodynamics teaches us that hot gas expands and moves faster than cool gas. When you leave a turbo "naked," it loses heat to the air, causing the exhaust gas to slow down and lose energy. The COBB Blanket keeps that energy trapped inside the housing. This keeps the exhaust velocity high, which spins the turbine wheel faster. The result? Less Turbo Lag and a throttle pedal that feels much more connected to the engine.

COBB offers this blanket in two distinct visual styles to suit your build.

• Standard Finish: Shows off the raw, natural look of the woven volcanic rock.

• Black Lava: Offers a murdered-out, stealth aesthetic for dark engine bays. Regardless of which color you choose, the specs are identical. Both use Volcanic Rock (Basalt) fiber because it is naturally fire-retardant and incredibly durable. Whether you are sitting in traffic or doing hot laps at the track, this blanket keeps the fire on the inside and the cool air on the outside.

COBB Tuning understands that heat management is the silent killer of performance. This turbo blanket is one of the most cost-effective modifications you can make. It protects your expensive engine components from heat fatigue while simultaneously making your car faster. It’s a win-win. Don't let your thermal energy bleed away—insulate it and use it.
