The year of your car just changes the coolant piping and whether they will need to send you the HTO early head design plugs and stuff. 808 (Patrick) ordered one not too long ago and his was press fit too I believe, he should be able to confirm it. From what I understand they all use the same upper blower press fit pulley snout now, the earlier versions of the M90 was keyed pulley. I am 99.9% certain on this!! I kind forgot you have cams and gears, Roush won't tune for that, but I would still send in the PCM for warranty and for the plugs.
