i think a 4 wire o2 sensor from repco would be alright... Bosch is the brand...
not sure on price..

Go the unit from Repco, or any other auto parts store.
The prices I got for the 2 wire one in my NA6 were
Mazda $430ish (Mazda)
Repco $90ish (Bosch)
MotorSpares $75ish (NGK)
Shop around.

my early na8 required a 4 wire o2 sensor, so i replaced the original nippon denso with a bosch universal which cost $109 from one of the national(?) autopart stores in phillip in the act. i did post the info in a thread, including part #, but the search engine isn't working so i can't find it, & no act phone book at the moment so can't look it up! btw, repco didn't have a 4 wire o2 sensor for the na8 but they might they might have the 1 wire one for the na6.

They do. The price I quoted above is for the 1 wire from Repco at Tugeranong, ACT.
In Canberra Motor Spares at Fyshwick (or Mitchell) is THE place to go for car bits.

Sorry for the thread revival;
Do the 1.6 NA's require the 1 wire bosch O2 sensor?

when i replaced the single wire on mine with a bosche, the car stopped being as revvy as it used to be, noticable under 4k rpms & especially on cold start mornings.
sounds normal?
