In my opinion, the best is the J35A4 from the '02-'04 Odyssey. This is because there are more of these engines than any other and it's the biggest. Others argue the J32A2 from the '01-'03 Acura CL/TL Type S is the way to go. However, these are much harder to find, so you'll pay a premium for them.26 jul 2010
