grab some numbers off of the 02 sensor. should have the ngk part number and then underneath that it should read A09 or A08 or A07 etc. the correct one is the A09.
the actual part numbers on the box are the same but different ones are made in different places and the federal vx calls for the A09. check out my thread for more info with pics.
