In stock now

MWR swap header for installing a 2ZZ-GE engine in your 2000-2005 MR2 Spyder.

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.


      • 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)
