GM LS3 Mass Air Flow MAF Sensor Weld Bung Flange Billet Aluminium

• 6061-T6 billet aluminium construction
• Precision machined
• For mounting an LS3 style MAF sensor to a custom intake pipe
• Underside of the bung has a machined radius to suit a 4" OD pipe. Will suit 2.5" to 5" with more weld.
• Includes weld bung and 2 sensor mounting bolts
• Compatible with:
• GM Gen III, IV, and V, engine RPO codes: LS3, LS7, LS9, LSA, LT1, LT2, L82, L83, L84, L86, L87, L8B, LT4, LT5
• 15865791, 23262343, 23262344, 22895480, 23144941, 2134222, 12576410, 2133134

• Application: This weld bung mounts an LS3 style MAF sensor to a custom intake pipe, suiting builds running a custom cold air intake, sheet metal intake or aftermarket piping where the factory MAF location isn't available.

• Size/Spec Context: The underside has a machined radius to suit a 4 inch OD pipe directly, with the flange suiting 2.5 inch to 5 inch OD pipe with additional welding to blend the radius to your specific pipe diameter.

• Construction Note: Precision machined from 6061-T6 billet aluminium for a strong, accurate mounting point that holds sensor alignment correctly for accurate airflow readings.

• Fitment Note: Compatible with GM Gen III, IV and V engines using MAF sensor part numbers 15865791, 23262343, 23262344, 22895480, 23144941, 2134222, 12576410 and 2133134, across RPO codes LS3, LS7, LS9, LSA, LT1, LT2, L82, L83, L84, L86, L87, L8B, LT4 and LT5. This is not a bolt-on part; welding is required to fit it to your intake pipe.

• What to Pair With: Commonly paired with a MAF sensor matching one of the confirmed part numbers, plus custom intake piping and a MAF sensor pigtail or adaptor harness if converting from a factory intake setup.

• Practical Buyer Tip: Since welding is required, confirm your pipe OD before purchase and expect to blend the weld to match if you're running anything other than a 4 inch pipe, so the sensor sits flush and reads accurately.

Note: this is not a bolt on part. Welding is required.
