I did a search and couldt find much on this issue. i know that from 05 that the hp went up 10 but then in 06 went down 9hp. whats the idea behind this?? is there a difference from 05 to 06 in engine makeup??

 

02-04 = k20A2 engine = 200 HP

05-06 = k20Z1 engine = 210 HP

in 2006 honda and acura adopted new SAE horsepower measuring or sumthing like that basicly the sales guy told me that there trying make measuring horesppower different or sumthing but thats all i know, SAE changed something and thats why it apears lower but yes it is still at 210 and the torque is still 140 even tho it saysother wise because i had the same question when i was purchasing my 06'

good luck with the purchase i love mine

 

No difference. Just new hp regulations.
