Industrial Injection 22B421 Standard Cover A/R Turbo Swap Kit Cummins - S467.7 90 for 6.7L

The Industrial Injection 22B421 is a Standard Cover S467.7 Turbo Swap Kit purpose-built for the 2010–2012 Cummins 6.7L diesel. Designed as a budget-friendly entry into big-turbo performance, this kit delivers a compelling combination of increased airflow, lower exhaust gas temperatures (EGTs), and strong street-to-track power gains without breaking the bank.

At the heart of this kit is the S467.7 turbocharger, featuring a 67.7mm forged milled compressor wheel (FMW) and an 83/74mm turbine wheel capable of flowing up to 85 lbs/min of air. The .90 A/R turbine housing is the tightest in the S467.7 lineup, promoting quicker spool-up and more responsive low-end boost compared to larger A/R options, making it an excellent choice for performance builds that still spend time on the street.

Key Features:

• S467.7 Turbocharger — 67.7mm FMW compressor wheel, 83/74mm turbine wheel
• .90 Turbine A/R Housing — faster spool-up and improved low-RPM response
• Standard Cover — budget-friendly compressor housing option
• 85 lbs/min airflow capacity — supports high-horsepower competition builds
• Lower EGTs — improved thermal management over the factory turbo
• Complete Install Kit — includes all hardware needed for a clean installation
• Injector upgrades recommended — to maximize spool-up and overall performance
