Paul G. Posted August 22, 2006 Share Posted August 22, 2006 The extra HP comes mostly from completely different cylinder heads with Variable Valve Timing. I own an '05 and have driven an '06 loaner and the difference is not really noticeable, maybe a bit more pull below 3000 rpm, maybe a bit less pull above 4000 rpm. Definitely not worth the trouble and expense. P. Link to comment Share on other sites More sharing options...
