All 2ZZ ECUs (stock and aftermarket) require only 1 upstream O2 sensor – this one goes in the bung on the right in the photo (cylinder #1). You may leave the left bung plugged or install an o2 sensor for a stock-like appearance but no sensor is needed in that left location.

Features:

• • • 100% stainless TIG welded construction
    • Polished finish
    • Thick 3/8″ flanges for excellent seal
    • Thick 16 gauge tubes for long service life
    • OEM-type multilayer steel inlet gasket included
    • OEM-type outlet gasket rings (2) included
    • 3 bolts and nuts included for outlet flange
    • Bolts directly to any year 2ZZ engine (with or without air injection) – no need to plug air injection ports
    • Bolts directly to stock or high performance (stock-fit) cat pipe
    • Oxygen sensor bungs in the stock locations, no welding required, inconspicuous appearance
    • Oxygen sensor bung plug (1) included for those who do not want to install the left oxygen sensor (not needed with 2ZZ ECU)

Often your original exhaust will be aged and rusty so many people prefer to replace UPSTREAM and DOWNSTREAM sensors rather than mess with the old ones which may be seized into your original exhaust
