Target the hot spots: Turbo turbine housing, downpipe first 2–3 feet, and nearby wiring/hoses.

Sleeve sizing: Measure hose/loom OD and pick the next size up for easy install.
Adhesive barriers: Degrease panels before sticking; use rollers for full contact.
Monitor temps: Pair with boost/EGT/fuel pressure gauges to validate results.

Frequently Asked Questions

What does a turbo blanket do on a 1st-Gen Cummins?

It keeps more heat in the turbine housing, helping spool and reducing radiant heat to nearby parts.

Should I wrap my exhaust manifold?

Many owners focus wrap on the downpipe/hot-pipe and use clamp-on shields for easy service. If you wrap cast iron, inspect periodically.

Gold vs. silver barrier—what’s the difference?

Both reflect radiant heat; gold films are highly reflective near IR. Choose size/thickness based on placement and clearance.

How do I choose heat sleeve diameter?

Measure the outside diameter of the hose/cable and select a sleeve with slightly larger ID for slip-on fit.

Where should I start if I only buy one item?

A turbo blanket or clamp-on pipe shield gives the biggest impact per dollar with minimal install time.
