They are identical, I believe. I swapped mine out with a ported IX one and noticed no differences.

Did you port the intake manifold as well? Combine they are worth 7-8whp. Just the throttle, there would probably little or no gains

03/04 tb's have a heat actuated idle air bleed flapper device. the 05/06 tb's do not have this.

you can install either tb onto either year evo, it will fit & work fine, however there is a slight difference.

i will post pictures tomorrow illustrating the differences.

Thanks captain obvious, way to go OT and yes I did both. Should be worth more power than that though.

oh man i just read it again. It is done on an exhange policy. I guess they dont use the same tb i send them. They just wait for mine to come in and then they ship the one already made. hmmmm

No offense, but the guy answering your questions performs the service you're looking for too. Maybe try that route.

+1 on what he said. MIL.Spec also doesn't charge $300, they cost less.

Sorry for reviving an old thread.

Is there any way to eliminate this temperature controlled idle flapper?

Thanks,

yeah, un due the screw, pull out the device, use plieers to physically pull out the mechanism & now your left with a aluminum piece that holds the o-ring. re-assemble.
