I too need to replace mine as well as a friends 02 sensors. Anyone with firsthand experience with aftermarket? Any comments/recommendations? I paid over $1000 CAD for a set of four from my stealership last time!
I found a few on fleabay and the prices vary drastically:
Carbon Everything
De-ambered
De-snorkled
Litronics
Eibach Pro Kit
Dansk Sport exhaust
Cheap Chinese headers
Silver console and bumperettes
AVIC D3
15mm H&R spacers in the rear
SSR GT3 19's
GT3 Carbon Replicas
Alcantera door panels
JL Aduio 5 channel powering Polks and Clif Designs
To do/complete:
Elemental Designs 10" subs in fiberglass enclosures behind seats
Carbon 3 spoke install with custom stereo control buttons (tiptronic wheel)
