simple question,

where to buy a new o2 sensor for the fd3s?

I saw one on rx7.com but the website seems has not been updated for at least a year?

any other website with paypal of course.

and also fuel filter online

 

i think i got my answer, need to look around more..

sorry.

this forum has so much info

 

check the FAQ under O2 sensor; there is a link for www.oxygensensors.com; they even have the sensor with OEM plugs so no need to splice a new one (like the one from RX7.com).
