Dial back under-hood temps and protect nearby wiring, hoses, and the cab with CPP Diesel’s curated turbo blankets, exhaust wraps, clamp-on shields, heat sleeves, and adhesive barriers for First-Gen 1989–1993 D250/D350. Mix and match components to keep heat where it belongs—inside the hot side.
Explore the full 1989–1993 Cummins catalog for complementary upgrades.
It keeps more heat in the turbine housing, helping spool and reducing radiant heat to nearby parts.
Many owners focus wrap on the downpipe/hot-pipe and use clamp-on shields for easy service. If you wrap cast iron, inspect periodically.
Both reflect radiant heat; gold films are highly reflective near IR. Choose size/thickness based on placement and clearance.
Measure the outside diameter of the hose/cable and select a sleeve with slightly larger ID for slip-on fit.
A turbo blanket or clamp-on pipe shield gives the biggest impact per dollar with minimal install time.
