Dependable Connector for Exhaust and Sensor Analysis
This O2 sensor connector is expertly crafted for off-road and diagnostic scenarios, where changes in the exhaust system could impact the accuracy of oxygen sensor measurements. It effectively mimics standard backpressure conditions, ensuring consistent O2 sensor outputs during vehicle assessments and performance testing.
High-Quality Construction for Longevity
Made from premium stainless steel (SS304), this connector guarantees robustness and extended usability. The built-in mini catalytic core is designed to sustain sensor performance in off-road conditions, eliminating the need for extra fittings or extensions.
Perfect for Off-Road and Diagnostic Uses
Tailored for automotive enthusiasts and garage experts, this connector is specifically intended for off-road or track testing only. It is not suitable for installation on vehicles used on public roads, as it does not serve as a substitute for an OEM catalytic converter.
Simple Installation for Effortless Use
With standard M18×1.5 threading, this connector can be installed rapidly into most O2 sensor ports. Just screw it in for a tight fit during testing processes—no special tools or wiring are necessary.

Before you order
Delivery How long will this take to arrive?
Most orders arrive within 4–12 business days of being placed. That covers 1–2 business days to prepare and dispatch your order, then 3–10 business days in transit depending on where you are. These are estimates based on what our carriers normally achieve, not guarantees. A tracking link is emailed the moment your parcel leaves us.
Read the shipping policyReturns What if it isn't right for me?
You have 30 days from delivery to start a return, for any reason. Email us first and we'll send the return address within 24 hours on business days, then ship the item back within 14 days. Items need to be unused and in their original packaging wherever that is still possible. Return postage is paid by the customer — unless the item arrived damaged, defective or incorrect, in which case we cover it.
Read the return policyRefunds When does the money come back?
Once your return reaches us and passes inspection, we confirm by email and refund the original payment method within 5–7 business days. Depending on your bank or card provider, it can take a further 5–10 business days to appear in your account.
Read the refund policyTracking Where is my order right now?
Every order ships tracked. Use the link in your dispatch email, or enter your order number on our tracking page at any time. Carriers usually need 1–3 business days to register the first scan, so an empty page straight after dispatch is normal.
