Funk Motorsport Nissan SR20 Manifold Blanket – Exhaust Heat Protection

SR20 Manifold Blanket for Targeted Exhaust Heat Management

The Funk Motorsport Nissan SR20 Manifold Blanket is a custom-fit exhaust insulation solution designed specifically for the SR20 engine platform. Drawing on Funk Motorsport’s expertise in motorsport and industrial thermal management, this manifold blanket helps SR20 owners control underbonnet temperatures, protect vital components, and support reliable performance in demanding conditions.

How the Nissan SR20 Manifold Blanket Works

This product is engineered to wrap directly around the SR20 exhaust manifold, creating a robust thermal barrier. By containing radiant exhaust heat, it helps prevent heat soak into the engine bay, reducing thermal stress on wiring, hoses, and intake components. The result is a cooler, more stable environment for both standard and turbocharged SR20 builds.

Where This Exhaust Protection Upgrade Is Useful

The SR20 manifold blanket is ideal for:

• Track and motorsport builds where engine bay heat can impact reliability and performance
• Off-road and expedition vehicles operating in high-load or low-speed environments
• Street-driven SR20-powered Nissans looking to reduce heat soak and extend component life
• Turbocharged applications where manifold heat can raise intake air temperatures

Owners seeking to protect sensitive engine bay components and maintain consistent performance will benefit most from this upgrade.

Key Benefits for SR20 Owners

• Helps reduce engine bay temperatures and heat soak
• Supports improved reliability for hoses, wiring, and plastics near the manifold
• Custom-fit for Nissan SR20 manifolds, ensuring targeted coverage
• Draws on proven Funk Motorsport heat insulation technology
• Useful for both naturally aspirated and turbocharged SR20 builds

Construction and Material Details

This manifold blanket is developed using insulation technology adapted from Funk Motorsport’s industrial heat management range. While specific material details are not disclosed by the manufacturer, the focus is on durability, precise fitment, and effective thermal containment for the SR20 exhaust manifold. The outer layer is designed to withstand high exhaust temperatures and harsh engine bay conditions, supporting long-term use in motorsport and off-road environments.

Installation and Fitment Guidance

The blanket is tailored for the standard Nissan SR20 exhaust manifold. Installation can typically be completed with basic hand tools and mechanical knowledge. For best results, install when the manifold is cool and accessible. If your vehicle features a non-standard or aftermarket manifold, check compatibility before purchase. Professional installation is not required but may be preferred for complex turbo or custom setups.
