For those running very high Exhaust Gas Temperatures (EGT’s), or wanting to stretch out the life of their O2 sensors, this Heat-Sink bung extender is the ideal accessory.  It pulls your sensor out of the direct exhaust stream and allows it to function in a semi-insulated environment to increase function and reduce damage in the presence of high EGT’s.

Perfect for many turbocharged and/or methanol applications.
