Hey while checking my fluids I kinda randomly began studying my intake manifold and have concluded that it is restricting the hell out of the air. I'm considering buying an after market ( y'all know the ones with the straight pipes instead of the stock loops.) my question is for anyone whose already done this how hard will it be to accomplish this job? Also what kind of performance gain could one expect ( I know not much but if anyone had numbers that would be great)

Well, you could buy one of the best looking intake for a Honda off ebay for less than $200 and put it together like people do with ITB's. No one has done it yet but it *should* work and is definatly bigger than stock if not ideal. They make some huge TB's for those things too.

nobody I know of produces one. It really sucks. I've been trying to get this guy to make one, but I have no idea where that's going.

will the honda manifold bolt up? or would you have to weld on new flanges to bolt it to the head?

Yeah exactly what modifications would one have to do to make that thing fit. And by Honda I'm assuming a civiv so would the car's year be important when shopping for one of these ( I obviously no nothing about Honda's)

We *may* have a sponsor coming out with a KA intake mani soon.

Stay tuned.

Well, if you look at the ITB writeups that have been done you'll see that they use heavy radiator hose to clamp the Suzuki TB's onto a hacked off KA Mani. What I was saying was to get a cheapo honda intake and hack it off so they can be mated together in the same fashion. Will it line up? Maybe, they could be a little off and the connectors would line them up. You'd probably need the straightest runners possible. Many I've seen do this...

Or something similiar.

BTW, the radiator hose thing is what BMW uses on the Euro E36 M3's and all E46 M3's so it isn't as ghetto as it sounds.

Thank god. It's about time somebody finally wised up to the thing being a total POS. Any chance of them making one for non-turbo applications as well?

Hell yeah thats great. I mean those loops in the stock mani have to go, besides the engine itself would look more "dressed up" with a aftermarket intake manifold
