1985-1989 C4 EGR Pipe Insulation Heat Shield
1985–1989 Corvette C4 EGR Pipe Insulation Heat Shield – Keeps the Heat Where It Belongs
Your 1985–1989 Corvette C4’s EGR (Exhaust Gas Recirculation) system plays a critical role in emissions and performance—but it runs hot. This EGR Pipe Insulation Heat Shield is a direct-fit solution engineered to protect surrounding components from excessive heat while preserving factory-correct appearance under the hood.
Designed to replicate the original GM part, this heat shield reduces heat transfer, prevents damage to nearby hoses and wiring, and maintains proper engine bay temperatures—especially important during high-performance or hot-weather driving.
Crafted from high-temperature insulating material with durable aluminum heat shielding, it installs easily over the EGR pipe and blends right in with your Corvette's OE look.
Why It Matters
When left unprotected, the EGR pipe radiates heat that can lead to brittle wiring, softened vacuum lines, or degraded connectors. This simple, effective part extends component life and keeps your engine bay safer and cooler.
