shitty cuz i got one off cal but it was the wrong one (stupid me for not checkin) so does n e one have an O2 sensor for a blacktop with turbine extention??
PDM sells the redtop sensor for 35bucks.
if you need the big one just drill and tap the O2 bung plug you got with the extention, it takes 5 minutes, and no it doesnt leak.
