Why Use Exoracing o2 plugs?

It's common to find one or two lambda ports in OEM and aftermarket exhaust systems; if you need to eliminate one or more ports, the best solution is our Exoracing o2 plugs!

Our o2 plugs are CNC machined from 304 stainless steel, ensuring a perfect plug that will be resistant to corrosion for years to come. 

By using a threaded o2 plug like ours, you can simply remove it if you need to use the lambda port again, unlike weld-in plugs, which are impossible to remove. 

If you have an aftermarket exhaust system, you may need to either add a port to accommodate a wideband sensor or remove one of the existing ports.

Our team has developed various solutions to this issue, including our lambda o2 sensor bungs or weld-in lambda ports, which are fully compatible with the universal M18x1.5 thread standard for narrowband or wideband sensors. We have also made our o2 sensor plugs with a 19mm head, which is a common socket size you'll be able to find in most tool kits!

These specific o2 Lambda sensor bungs are crafted using high-grade stainless Steel to prevent rusting or deterioration over time, ensuring the longevity and reliability of your exhaust system.
