Universal O₂ Sensor Spacer for cars

🚗 **O₂ Sensor CEL Fix: Mini Catalytic Converter Spacer (M18x1.5 Universal)**

Say goodbye to that persistent **check engine light (CEL)**! The **Universal O₂ Sensor Spacer** is precision-engineered to **optimize exhaust readings** and eliminate false error signals triggered by aftermarket exhausts or hi-flow catalytic converters. This essential adapter is built to restore smoother engine performance while **preventing unnecessary CEL triggers**.

✅ **Eliminate False Check Engine Alerts**

Our O₂ sensor spacer minimizes incorrect oxygen sensor readings, ensuring your Engine Control Unit (ECU) interprets exhaust values correctly. This helps maintain optimal **air-fuel ratios** and **consistent engine performance** without the frustration of constant warning lights after exhaust system modifications.

**Built-In Mini Catalytic Filter Core**

The spacer features an integrated **micro catalytic filter core**. This miniature catalytic chamber supports improved and more stable exhaust gas readings by treating the sample gas entering the O₂ sensor. This is the key feature that helps prevent the CEL from appearing unnecessarily after installing performance exhaust parts.

Premium 304 Stainless-Steel Durability

Crafted from solid **304-grade stainless steel**, the spacer is designed for maximum resistance against corrosion, extreme heat, and impact. Each unit is **CNC-machined** for precision **M18x1.5 threading** and reliable, leak-free performance, guaranteeing long-lasting reliability even in the harshest engine bay conditions.

Quick, Universal M18×1.5 Installation

Installation is simple and fast. The **M18×1.5 threaded design** offers a **universal fit** for most vehicles equipped with standard O₂ sensors. Simply screw the spacer into your existing exhaust port, reattach your sensor, and you’re done—no complex modifications or specialized tools are needed.
