Anyway, personally, I would strongly consider having that thing tuned. `Not necessarily because you are leaving power on the table but just due to the short-term and long-term fuel trims changes. `(You did reset the ECM after the mods right?) `I would have NEVER believed it but... (always a `but`) I added some long tubes, y-pipe, and a Superchips program to my Dodge Ram 5.7 1/2 ton and 30K later I got the 0420 code. `Replaced the factory 02s and cat with an aftermarket Magnaflow... 5K later... another 0420. `Let`s just say I`ve got 1k in catalytic converters and 02 sensors since the bolt-ons and that is CHEAP because I did all the cutting and welding in my shop. `I ended up doing some things that I won`t mention here to solve the problem. `After I remedied the code issue I eventually I took it to a local shop and my fuel trims and A.F.R. were way out of wack due to the increased scavenging of the exhaust.`
`
So just because it`s not throwing a code now... doesn`t mean it won`t in the future. `At the very least data-log that thing! `(Not trying to rain on your modification fun... really I`m not. `Just don`t want to see what happened to me happen to anyone else!)
`
Anyway, back to the fun!
`
Skip the cold air intake... you would need forced induction to warrant any increase in intake cfm or velocity. `The cost/ benefit just isn`t there.
Again, I`m Honda performance challenged but is a .2 liter increase in displacement really a reason for an engine swap? `Surely there is a shop somewhere that can grind custom cams or has some off-the-shelf profiles for your current V6? `Maybe mill the heads to increase compression and have a good head shop port them? `(I know one if you are looking!) `Combine new cams, springs, headwork, with some good tuning... that Accord could be pretty fun!
`
However, something I`m sure of... I do like the new DW-1 ATF... much better than Z-1.
