Q: Does the S&B 75-5126 require a tune on the F-150 3.0L diesel?

No tuning is required. The S&B 75-5126 and 75-5126D work with stock calibration and are also compatible with enhanced tuning. The MAF Extension Harness maintains OE signal values so no recalibration is needed.

The S&B 75-5126 Cold Air Intake is a sealed-airbox performance upgrade for 2018-2020 Ford F-150 trucks with the 3.0L Power Stroke diesel engine, engineered to flow 20.41% better than stock (oiled version) or 16.67% better than stock (dry version). It features a fully enclosed airbox with a large clear lid, a silicone air scoop, and a MAF Extension Harness and Bracket that repositions the MAF sensor further down the intake tube to maintain OE signal values and avoid Check Engine Lights. The 75-5126 includes the 8-layer cotton cleanable oiled filter; the 75-5126D includes the dry extendable media filter. No tuning is required with either version.

Buy this if...

Your truck is a 2018-2020 Ford F-150 with the 3.0L Power Stroke diesel engine
You want measurably more airflow and a sealed cold air intake with no CEL risk
You want a drop-in upgrade that works with stock calibration or an existing tune

Do not choose this if...

Your truck is a 2021 F-150 3.0L - S&B lists a 2021 fitment on their site but the source confirms 2018-2020; verify with S&B before ordering a 2021
You need a stock-replacement airbox with no performance change

Verify before ordering...

Confirm model year is 2018-2020 and engine is the 3.0L Power Stroke diesel
Choose your filter - 75-5126 (oiled, 20.41% flow gain) or 75-5126D (dry, 16.67% flow gain)

Oiled or Dry - Which Filter to Choose

Both the 75-5126 and 75-5126D are the same sealed intake system. The difference is the filter media and the resulting airflow numbers. The oiled cotton filter flows more air; the dry filter captures particles more efficiently. Neither requires tuning.

Spec	75-5126 - Oiled Cotton Filter	75-5126D - Dry Extendable Filter
Airflow vs Stock	+20.41%	+16.67%
ISO 5011 Efficiency	99.29%	99.54%
Filter Media	8-layer cotton cleanable	Dry extendable synthetic
Maintenance	Clean and re-oil with S&B cleaning kit	Remove debris at service intervals
Replacement Filter	KF-1058 (oiled)	KF-1058 (dry option)
Best For	Maximum airflow, comfortable with filter cleaning	Higher filtration efficiency, no-oil maintenance

If your fitment matches and your filter preference is clear, choose your version and proceed. Replacement filters for both versions are available as KF-1058 - select oiled or dry when ordering.

Why This Intake Avoids Check Engine Lights

Most intake systems that move the MAF sensor trigger CELs because the sensor's position changes the signal the ECU expects. S&B addresses this directly by including a MAF Extension Harness and Harness Bracket that repositions the MAF sensor further down the intake tube while maintaining OE signal values. The result is measurably more airflow with no CEL on stock calibration or with an existing tune. For a 2018-2020 Ford F-150 3.0L owner who wants a proven sealed cold air upgrade without tuning, the 75-5126 or 75-5126D is the correct intake to order.

Tuning Required: No - works with stock calibration or enhanced tuning

Warranty: S&B Million Mile Warranty

ISO 5011 Tested: Yes - meets or exceeds ISO 5011 standards

Filter Choice: Select oiled (75-5126) or dry (75-5126D) at checkout

S&B 75-5126 Key Features

Every component in the 75-5126 system is purpose-built for the 3.0L Power Stroke intake path:

Fully enclosed airbox - protects the filter from dirt and isolates it from engine heat
Large clear lid with rubber seal - seals out engine heat; clear for quick visual filter inspection
Large silicone air scoop - directs cold air to the filter for additional airflow benefit
MAF Extension Harness and Bracket - moves MAF further down the tube to maintain OE signal values
Premium silicone components - filter, coupler, tube seal, and scoop; rated to 400F; will not crack
ISO 5011 tested - both oiled and dry versions pass S&B's rigorous ISO test protocol

Install Overview - S&B 75-5126

Install requires battery disconnection and transfer of the MAF sensor from the stock intake to the S&B tube using the included MAF Extension Harness and Harness Bracket.

What To Expect On Install

Tuning: Not required
Reversible: Yes - S&B recommends keeping all stock parts
MAF sensor: Transfers from stock intake using the included harness and bracket

Battery Disconnect Requirement:
S&B requires disconnecting the negative battery cable and waiting a minimum of 2 hours before completing installation. Failure to do so may cause the Check Engine Light to illuminate. This step cannot be skipped.

Fitment - 2018-2020 Ford F-150 3.0L Power Stroke

Confirmed fitment for 2018-2020 Ford F-150 trucks equipped with the 3.0L Power Stroke diesel engine.

2018 Ford F-150 3.0L Power Stroke
2019 Ford F-150 3.0L Power Stroke
2020 Ford F-150 3.0L Power Stroke

S&B's own product listing also references 2021 fitment. If your truck is a 2021 F-150 3.0L, contact S&B at (909) 947-0015 to confirm the correct part number before ordering - their install instructions also note a specific MAF Extension Harness requirement for 2021+ applications.

Avoid These Common Mistakes

Skipping the 2-hour battery disconnect - CEL will likely trigger if this step is missed
Ordering for a 2021 F-150 without verifying - the 2021 application may require a separate MAF harness; confirm with S&B first
Choosing a filter version without checking the airflow numbers - oiled flows 20.41% over stock, dry flows 16.67% over stock
Assuming this is the same intake as the Super Duty 6.7L system - this kit is specific to the F-150 3.0L Power Stroke only

Before You Order

Model year confirmed as 2018-2020, engine confirmed as 3.0L Power Stroke diesel
Filter version selected - 75-5126 (oiled) or 75-5126D (dry)
2-hour battery disconnect planned before starting installation

For 2018-2020 Ford F-150 3.0L Power Stroke owners who want a sealed cold air upgrade with measurably more airflow and no CEL risk, the S&B 75-5126 or 75-5126D is the correct intake to order.

Click or tap a question below to expand the answer.

Does the S&B 75-5126 fit a 2019 Ford F-150 3.0L Power Stroke?

Yes, the S&B 75-5126 and 75-5126D are confirmed for 2018-2020 Ford F-150 trucks with the 3.0L Power Stroke diesel engine. Both the oiled (75-5126) and dry (75-5126D) versions fit this application with no modifications required.

What is the difference between the S&B 75-5126 and 75-5126D?

The 75-5126 uses an 8-layer cotton cleanable oiled filter and flows 20.41% better than stock with a 99.29% ISO 5011 efficiency rating. The 75-5126D uses a dry extendable media filter and flows 16.67% better than stock with a 99.54% ISO 5011 efficiency rating. The dry filter captures particles slightly more efficiently; the oiled filter flows more air. Both are the same sealed airbox system. Select your preference at checkout.

Will the S&B 75-5126 cause a Check Engine Light on my F-150 3.0L?

No, when installed correctly. The 75-5126 includes a MAF Extension Harness and Harness Bracket that repositions the MAF sensor further down the intake tube while maintaining OE signal values. S&B specifically engineered this system to avoid Check Engine Lights with stock calibration or enhanced tuning. The one CEL risk is skipping the required 2-hour battery disconnect before completing installation - S&B states this step cannot be skipped.

Does the S&B 75-5126 require a tune on the F-150 3.0L diesel?

No tuning is required. The S&B 75-5126 and 75-5126D are engineered to work with stock calibration and are also compatible with enhanced tuning. The MAF Extension Harness maintains OE signal values so the ECU reads the intake correctly without any recalibration.

Will this fit a 2021 Ford F-150 3.0L Power Stroke?

Confirmed fitment is 2018-2020. S&B's own product page references 2021 fitment, and their install instructions note that 2021+ applications may require a separate MAF Extension Harness (part number AI2761-00). If your truck is a 2021 F-150 3.0L, contact S&B at (909) 947-0015 before ordering to confirm the correct part number and whether the additional harness is required.

What replacement filter does the S&B 75-5126 use?

The replacement filter for both the 75-5126 and 75-5126D is the KF-1058. Select the oiled or dry option when ordering the replacement to match your current filter type.
