Stainless Steel Oxygen Sensor Spacer – M18×1.5 Threaded Extension Fitting
Heavy-Duty Extension for Automotive and Exhaust System Upgrades
💎 Solid Stainless Steel Build
Constructed from high-grade stainless steel, this oxygen sensor spacer delivers excellent resistance to rust, heat, and mechanical wear. Built to perform in harsh under-hood conditions and extended use.
🔥 Withstands High Heat & Pressure
Engineered to maintain form and function under extreme exhaust heat and pressure. Ideal for engine bays and performance systems exposed to continuous thermal cycling.
⚙️ Precision Threads for Leak-Free Fit
Designed with CNC-machined M18×1.5 threads for fast, secure, and hassle-free installation. Achieve a snug, sealed fit without leaks or thread damage.
📏 Compact Size for Tight Spaces
At just 1.8 inches tall, this adapter fits easily into confined areas without interfering with nearby components—great for custom builds and tight installations.
🔧 Compatible with Standard O2 Sensors
Universal M18×1.5 threading fits most oxygen sensors used in automotive applications. Commonly used for tuning, fixing error codes, or repositioning sensors on modified exhausts.
🛠 Quick 4-Step Setup
Install in minutes: remove your old sensor fitting, insert this spacer, hand-tighten, and finish with a wrench. No welding, cutting, or advanced tools needed.
🚗 Helps Prevent Engine Light Warnings
Repositions the O2 sensor slightly away from direct exhaust flow to reduce false readings and potential check engine light triggers—commonly useful after exhaust mods.
💠 Superior Alternative to Aluminum Adapters
Outperforms basic aluminum or zinc-plated spacers with higher strength and corrosion resistance. A more reliable choice for mechanics, enthusiasts, and professionals alike.
