ISIS Performance O2 Sensor Adapter - FOR Nissan SR20DET
Part # IS-O2ADPT
Have a Megan Racing, GReddy, or ISIS turbine
outlet and don't want to buy a new O2 sensor because yours won't fit?
adapter enables the use of the skinny-type O2 in the larger fat-type sensor bung.
No need to go searching for that other O2 sensor when using aftermarket turbine outlet. Adapter can also be used as block-off.
