Product Description
Keep under-hood heat in check and protect nearby components with the Industrial Injection 121701 T6 Turbo Blanket. Designed for T6 turbine housings (S400/S500 frame and similar), this blanket helps reduce radiant heat, speeds warm-up of the turbine housing, and can improve spool consistency on single or compound setups.
Fitment
- Engine/Platform: 1989–1993 Dodge Ram with 5.9L Cummins (12-valve)
- Turbo Interface: T6 turbine housings (S400/S500 frame and similar)
- Important: First-gen Cummins trucks were not factory T6—this blanket fits builds that have been upgraded to a T6-flanged turbo. Verify your turbine housing is T6 before ordering.
Why It Works
- Contains heat at the turbine housing to lower under-hood temperatures
- May improve spool characteristics and protect wiring, hoses, and paint
- Includes stainless ties for securement
Recommended Parts (CPP Diesel only)

FAQs
Will this fit my stock 1989–1993 Cummins turbo?Probably not. The factory turbo on first-gen trucks is not T6. This blanket fits T6 housings only—common on S400/S500 upgrades. Confirm your turbo’s turbine inlet is T6 before purchasing.
Can I use this on compound turbo setups?
Yes. It’s suitable for single or compound configurations as long as the turbine housing you’re covering is T6.
Does the kit include mounting hardware?
Stainless ties are included for securing the blanket. For manifold/turbo mounting hardware, see our turbo studs & hardware.
What if my truck uses a T3 or T4 housing?
