is there any one can tell me the part # of the oil filter? just go buy the oem one or the TRD better? please let me know,, Thank you

The current toyota number is 90915-yzza2. Still looking for the TRD number myself.

for the xa and xb the TRD filter part is 00602-90915-005

Using Autozone.com and Scion xB 2004, STP filter#S4967 and Mobil#M1-103. I installed the Mobil filter last week, works fine.

YOU CAN USE THE TOYOTA PART # 90915YZZA1 IT IS A LONGER FILTER AND WILL FIT PERFECT
