Extreme exhaust heat radiates from the turbine housing and cooks the wastegate actuator diaphragm through repeated heat cycles, causing it to harden, crack, and lose consistent boost control over time. The Lava Waste Gate Shield from Heatshield Products wraps the wastegate body to retain heat where it belongs, inside the turbine, while protecting the actuator and surrounding components from destructive radiant exposure.
Proprietary Inferno Mat insulation at the core. The inner layer uses Heatshield Products' Inferno Mat material, rated for continuous exposure up to 1800°F and intermittent peaks up to 2000°F. That thermal barrier keeps temperature fluctuations at the actuator to a minimum, so the diaphragm cycles consistently rather than expanding and contracting erratically with every boost event.
Lava Shield outer layer adds structure and secondary insulation. The outer wrap provides an additional insulation barrier and a carbon-fiber appearance, keeping the shield pliable and intact across countless heat cycles without cracking or delaminating. Inconel wire secures the assembly, holding position under vibration and high under-hood temperatures.
No wastegate removal required. The shield installs directly onto the wastegate body in minutes without disturbing boost lines, sensor connections, or the actuator itself. Removal for inspection or service is equally straightforward, even after long-term heat exposure.
Available in three sizes to match common wastegate diameters. SKU 300172 fits 40 mm turbo wastegate bodies, SKU 300174 covers 44-46 mm bodies, and SKU 300176 fits 66 mm bodies, so the shield works across a broad range of OEM and aftermarket turbocharger applications.
Product Benefits
- Diaphragm Protection: Retains heat inside the turbine housing to stop radiant heat from degrading the actuator diaphragm.
