[1991f22a1]

i decided just to post some pics of my hybrid intake mani im ready to put in it except for the time, as my baby is my daily driver. im aiming for this sunday hopefully. there is quite a bit of stuff missing from the mani but thats bcuz im reusing most of it off the a1. enjoy the pics, will post more of the install when it happens

Nice man, only thing is I would put the butterfly plate on top right below the plenum, otherwise you can get unwanted turbulence when they are closed.

ive talked to alot of people about that and they all have agreed that on the bottom was the best place for them. i was also thinking on top but its not like once i get the mani in it will hard to switch them if i need

congrats, I have the same hybrid intake manifold. Definitely a difference in power, and sound!

the spacer adds an extra oomf, icing on the cake.

have you wired the IAB and running the pt6 ecu?

i got the infamous black box but didnt pull the pigtails for it so no they are not hooked up at the moment. but i do have the ecu so when i get the connector "pigtails" i will install them. i want to run them cuz i want that low end torque

i'm in the process of rebuilding my a6. i'm just going to polish my intake to get added air flow. is the h23 intake just a bigger mm? i've been told a polished a6 intake provides the same flow as a stock h23 is this true?

the plenum on the h23 utilizes a bigger TB, 2mm to be exact, and to me the plenum itself looks a lot bigger than that of an a6. as far as figures go for the runners from what iver heard they are the same size diameter wise, but the a6 runners are shorter than the h23's.

I'm almost ready to do this too. Just finished cleaning the egr ports last night. Did you have to drain your coolant? I'm also concerned how it will affect gas mileage coz I drive mine daily.

no you dont have to drain the coolant, but you do have to remove the thermosat hoses that connect to the intake mani itself and i did loose a lot of coolant, so make sure you have that handy, also make sure you have the correct size hoses to replace the ones that arent long enough. i dont see it affecting your mpg except that itll be harder to keep your foot out of it. thats always been my problem

im going to be running the same thing what stud/bolt length did you go with?

i ordered the extended bolt kit from blacktrax.com but they are a hex head design which i hate (hex heads suck) but it only cost me 17 bux. ive heard you can use the bolts from the f22 ac compressor and also some from the h23 i think. probably cheaper but i didnt find out unitl i had already purchased the bolt kit
