Vibrant O2 Sensor Restrictor Fitting (90-DEGREE) w/ Adjustable Jets (CEL Eliminator)

Vibrant O2 Sensor Restrictor Fitting

2005–2022 Chrysler, Dodge, Jeep Vehicles with Aftermarket Headers & Mid Pipes

19019 + 19999

Overview:

The Vibrant O2 Sensor Restrictor Fitting with Adjustable Jets is a precision-engineered solution designed to eliminate the common Check Engine Light (CEL) issue encountered when installing long-tube headers and aftermarket mid-pipes that remove or replace the OEM catalytic converters on Chrysler, Dodge, and Jeep vehicles. This fitting simulates the presence of a catalytic converter by restricting oxygen sensor readings, preventing false P0420 codes and ensuring smooth engine management.

Ideal for enthusiasts upgrading their exhaust systems, this restrictor fitting maintains proper sensor feedback without compromising engine performance or drivability. It is especially beneficial for vehicles equipped with high-flow catalytic converters or those that have completely eliminated catalytic converters.

Key Features:

Designed with precision and durability in mind, the Vibrant O2 Sensor Restrictor Fitting offers the following key features:

• 90-degree oxygen sensor simulator fitting that redirects sensor readings to prevent CEL triggers
• Optional adjustable jet inserts to fine-tune oxygen sensor signals based on exhaust setup
• Recommended use of the largest orifice jet for vehicles with aftermarket high-flow catalytic converters
• Middle size jet recommended for vehicles that have fully eliminated catalytic converters
• Thread size M18 x 1.5 compatible with OEM oxygen sensor threads
• Constructed from high-quality T304 stainless steel for corrosion resistance and longevity
• Sold individually; two units required for left and right side O2 sensors
• Effectively eliminates P0420 check engine codes related to catalytic converter removal
• Compatible with a wide range of Chrysler, Dodge, and Jeep models equipped with aftermarket headers and mid-pipes

Construction & Design:

The Vibrant O2 Sensor Restrictor Fitting is crafted from premium T304 stainless steel, ensuring exceptional durability and resistance to heat and corrosion commonly found in exhaust environments. Its 90-degree design allows for easy installation in tight spaces without compromising sensor orientation. The fitting includes optional adjustable jets that allow precise calibration of oxygen sensor readings, tailored to the specific exhaust modifications of your vehicle.

Manufactured to OEM thread specifications (M18 x 1.5), this restrictor fitting guarantees a secure and leak-free connection with factory oxygen sensors, maintaining the integrity of your exhaust system.

Installation & Fitment:

Installation is straightforward and requires no permanent modifications to your vehicle’s wiring or sensors. The restrictor fitting is installed in place of the oxygen sensor located downstream of the catalytic converter position, typically after the aftermarket headers or mid-pipes. Two fittings are needed to cover both left and right bank sensors.

This product is specifically designed for Chrysler, Dodge, and Jeep vehicles equipped with 5.7L, 6.1L, 6.2L Hellcat, 6.4L Hemi, 8.0L, 8.3L, 8.4L V10, 2.7L, 3.5L, 3.6L V6, 3.7L, 4.7L, 5.2L, and 5.9L Magnum engines that have aftermarket headers and mid-pipes which replace or eliminate OEM catalytic converters.

What's Included:

• 1 x Vibrant 90-degree O2 Sensor Restrictor Fitting (Part #19019)
• Optional Adjustable Jet Inserts (Part #19999) – sold separately but recommended

Ideal For:

This restrictor fitting is perfect for automotive enthusiasts and professional tuners who have upgraded their exhaust systems with long-tube headers and aftermarket mid-pipes that remove or replace catalytic converters on Chrysler, Dodge, and Jeep vehicles. It is especially useful for those experiencing persistent Check Engine Light codes related to oxygen sensor readings and catalytic converter efficiency.

Whether you run high-flow catalytic converters or have eliminated them entirely, the Vibrant O2 Sensor Restrictor Fitting provides a reliable, cost-effective solution to maintain engine management system harmony and avoid unnecessary diagnostic trouble codes.
