The S&B 75-5080 is a sealed cold air intake for 2006-2007 Chevy Silverado and GMC Sierra 2500HD / 3500HD 6.6L LBZ Duramax trucks - a fully enclosed airbox with a clear polycarbonate lid that outflows the stock LBZ intake by 50.15% with a 99.41% ISO 5011 efficiency rating. The kit includes two airflow configurations via an included silicone box plug, an injection-molded MAF plate with true O-ring seal, and all silicone components rated to 400F. No tuning is required and the intake is CARB compliant in all 50 states. Filter type - oiled cotton cleanable (75-5080) or dry extendable (75-5080D) - is selected at checkout.

Buy this if...

You want improved sealed cold air intake performance on a 2006-2007 6.6L LBZ Duramax.
Your truck runs stock calibration or an enhanced tune and you want no CEL after install.
You want a no-tune bolt-on airflow upgrade backed by a million mile warranty.

Do not choose this if...

Your truck falls outside the 2006-2007 LBZ Duramax range - other Duramax generations require different S&B part numbers.
You prefer an open air intake design with an exposed filter and louder turbo sound - this is a sealed airbox design.

Verify before ordering...

Year is 2006-2007 and engine code is the 6.6L LBZ Duramax - Silverado or Sierra 2500HD / 3500HD.
Filter type decided: oiled cleanable (75-5080) or dry extendable (75-5080D) - selected at checkout.

Oiled or Dry Filter for the LBZ 75-5080?

The 75-5080 and 75-5080D use the same sealed airbox, intake tube, and hardware. The oiled cotton version flows 50.15% over stock with a 99.41% efficiency rating. The dry version flows 48.39% over stock with a 99.44% efficiency rating. Both exceed the 99% ISO 5011 threshold.

Choose the 75-5080 oiled for a reusable 8-layer cotton filter washable with an S&B cleaning kit - replacement filter is KF-1035. Choose the 75-5080D dry for no-oil maintenance serviced by blowing out debris - replacement is KF-1035D at the same link. If your fitment and filter preference are confirmed, this is the correct LBZ Duramax intake to order.

What the S&B 75-5080 Adds to Your LBZ Duramax

The 75-5080 is a completely redesigned intake for the LBZ platform - not a carryover from the LLY generation. S&B redesigned the airbox, seals, and intake tube using premium silicone components throughout. The fully enclosed airbox protects the filter from engine heat and debris. The clear polycarbonate lid with silicone edge trim snaps on and off for tool-free filter inspection without removing the intake tube.

Two airflow configurations are available using the included silicone box plug. Remove it to open the secondary inlet for maximum airflow. Install it to seal the secondary inlet and use the front-facing inlet as the primary airflow source - useful in conditions where minimizing debris ingestion is preferred. The injection-molded MAF plate creates a true O-ring seal to the stock MAF sensor, maintaining proper airflow mapping for stock and enhanced calibrations without a CEL.

Avoid These Common Mistakes

Ordering for a 2007.5-2010 LMM Duramax - the 75-5080 is confirmed for 2006-2007 LBZ only. The LMM uses the S&B 75-5091.
Ordering for a 2004.5-2005 LLY Duramax - the LLY uses the S&B 75-5102. Verify your engine code before ordering.
Selecting the wrong filter type at checkout - oiled cotton (75-5080) is reusable / washable; dry (75-5080D) is service-and-replace. Both use the same airbox - the difference is maintenance style only.

Frequently Asked Questions

Click or tap a question below to expand the answer.

Will the S&B 75-5080 fit my 2007 Silverado 2500HD LBZ Duramax?

Yes - the S&B 75-5080 and 75-5080D are confirmed for 2006-2007 Chevy Silverado and GMC Sierra 2500HD / 3500HD trucks with the 6.6L LBZ Duramax. A 2007 Silverado 2500HD LBZ is within the confirmed fitment range. Note that 2007.5 trucks may have the LMM engine code - if your truck was built after July 2007, verify the engine code before ordering.

Does the S&B 75-5080 require tuning on the LBZ Duramax?

No tuning is required. The 75-5080 uses an injection-molded MAF plate with a true O-ring seal that maintains proper MAF sensor airflow mapping for stock and enhanced calibrations. No CEL, no recalibration needed.

What is the difference between the S&B 75-5080 and 75-5080D?

The 75-5080 includes an oiled 8-layer cotton cleanable filter that flows 50.15% over stock and can be washed and re-oiled for long-term reuse - replacement filter is KF-1035. The 75-5080D includes a dry extendable filter that flows 48.39% over stock with no oil required, serviced by blowing out debris - replacement filter is KF-1035D. Both use the same sealed airbox. Select your preference at checkout.

Is the S&B 75-5080 LBZ Duramax intake CARB legal in California?

Yes - the S&B 75-5080 carries CARB EO # D-590-15 and is legal for use in all 50 states including California. The CARB label included with the kit must be affixed in a visible location in the engine bay after installation.

Will the S&B 75-5080 fit the 2007.5 LMM Duramax?

No - the 75-5080 is confirmed for the LBZ engine code only, covering 2006 through the early-build 2007 production trucks. The 2007.5 and later LMM Duramax uses the S&B 75-5091. If your 2007 truck was produced after mid-year, verify the engine code before ordering to ensure you select the correct intake.

My 2006 Sierra 2500 feels sluggish under load - would this intake help?

If intake restriction is contributing to reduced turbo response or low power under load, the S&B 75-5080 - which outflows the stock LBZ intake by 50.15% - may support improved turbo efficiency and throttle response. Intake restriction is one of several possible factors in reduced performance; if the cause has not been confirmed, verify the overall air system condition before ordering.
