Denso makes a good 02 sensor that seems to last longer than the others , at least for the turbo Buicks, & I assume that the same one will work on TTA's, keeping in mind that nothing lasts forever. Denso # 234-1001 for the turbo Buicks, & maybe the same # for you. BTW, this is not a heated sensor. HTH
I've been running the Denso for abuot 2 yrs now, I usually run nothing
but 110-112 octane. I can run about 40-50 gallons of race gas thru the
car before the O2 CC's get real lazy.
