90915-YZZG1
I used to install the 90915-YZZD1. The only problem with that one is engine noise. I went to poway toyota and told them about the problem and they gave me 90915-YZZG1 then engine ran more quiet and smoother than ever.
They told me there are more alternate toyota part numbers for our supras depending on maintenance purposes. The only reason why the other dealer gave me the D1 is because its the one that was commonly used.
