Helpful Notes

Turbo blankets: Reduce radiant heat and can improve spool/response; match T3/T4/T6 to your turbine housing.
Wrap width: 1"–2" works for downpipes and tight routing; 6" is fast on long, straight sections.
Barrier film: Add reflective barrier to the firewall/floor to cut cab heat and noise.
Hardware: Use stainless snap straps or high-temp ties; clean oils off surfaces before application.

Frequently Asked Questions

Do turbo blankets actually lower under-hood temperatures?

Yes. Quality blankets contain turbine heat and reduce radiant temps around wiring and hoses. See our BD T3/T4/T6 options above for common S300/S400 housings.

What exhaust wrap size should I choose for a Second-Gen downpipe?

Most builds use 2" wide wrap (e.g., Thermo-Tec 11023/11022-25). Use 1" where bends are tight; 6" speeds up straight sections.

Will adhesive barrier films hold up in the cab/firewall area?

Yes—products like Thermo-Tec 14610 are designed for radiant heat and sound damping on interior panels.

Is titanium wrap better than fiberglass?

Titanium (e.g., PPE) is more durable against abrasion and can be easier to work with; high-temp fiberglass wraps remain cost-effective and proven.

Where do I start if I only add one heat control item?

Start with a turbo blanket for maximum radiant heat reduction, then add wrap on the downpipe and a small barrier film section near the firewall.
