yeh it fits . Took it down Sydney a few weeks ago,called in to Spiro at Autotech.9A.M. Gave him a G6ET ,an old capa box & $2500.Asked him to do his magic . 5 P.M picked up G6ET ,dump, cat @ tune. Went from 221 RWKW TO 283 RWKW with the biggest ,widest torque curve I have ever seen. Plus change .Nothing scares me at the lights any more,I just dawdle away feeling very superior.
