💎 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. 📘 Specifications Material: Stainless steel Thread size: M18 x 1.5 Height: 1.8 in / 46.5 mm Top diameter: 0.63 in / 1.6 cm Base diameter: 0.86 in / 2.2 cm Features: Rust-proof, heat-resistant, heavy-duty thread, compact form Use: Oxygen sensor spacing, tuning, engine code correction ❓ FAQ 1.
