Vibrant O2 Sensor Restrictor Fitting w/ Adjustable Jets
- The Male end of these adapter fittings are designed to thread into an M18 x 1.5 Female Exhaust Sensor Bung.
- Manufactured entirely from 304 Stainless Steel.
- 1 set per bag.
-Just replaced your Chevrolet Silverado Catalyst, now after a year the light is back on? We found the O2 sensors are to sensitive and adding the restrictive orifice with even the largest jet we cured this problem with ease.
-When adding Long-Tube Headers and Aftermarket Mid-Pipes that eliminate the OEM Catalytic Converters, it is common to throw a Check Engine Light
-Will keep you engine light off with aging exhaust systems
-Works well with performance exhaust and performance catalytic systems
