The Vibrant Performance J-Style Oxygen Sensor Defouler is a compact, high-quality adapter designed to reposition an oxygen sensor away from the direct exhaust gas stream.
Its unique 90-degree J-shaped design allows the oxygen sensor to sit parallel to the exhaust pipe rather than extending straight outward, making it especially useful in tight spaces where exhaust piping, heat shields, or underbody components limit clearance.
Manufactured from durable T304 stainless steel, this fitting offers excellent resistance to heat, corrosion, and the harsh conditions found in automotive exhaust systems.
Features and Benefits
-
90-degree J-style design positions the oxygen sensor parallel to the exhaust pipe for improved clearance.
-
T304 stainless steel construction provides excellent corrosion resistance and long-term durability.
-
M18 x 1.5 male and female threads fit standard threaded oxygen sensors and exhaust sensor bungs.
-
Adjustable orientation allows the fitting to be rotated for optimal sensor positioning.
-
Compact design offers better clearance than the original, longer version.
-
Universal application for compatible threaded oxygen sensor installations.
Compact, Updated Design
In mid-2021, Vibrant redesigned this defouler with a shorter overall length to improve fitment in tight spaces.
The updated version retains the same 90-degree configuration and M18 x 1.5 threading as the original, but its more compact dimensions make installation easier where clearance is limited.
Fitment and Installation
This is a universal-fit component designed for exhaust systems equipped with standard M18 x 1.5 threaded oxygen sensor bungs.
The male end threads into the exhaust pipe's existing oxygen sensor bung, while the oxygen sensor threads into the female end of the adapter.
Important: Verify available clearance and oxygen sensor thread size before ordering. This fitting is not compatible with older flange-mounted or bolt-on oxygen sensors.
