The cost is almost double.

My *guess* is about twice as reliable. For example, let's say aftermarket twins are 99% reliable over any three year period. A single would probably be about 99.5% reliable over that period of time (0.5% failure rate for a single vs. 1.0% failure rate for twins).

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
