how hard to install manifold?

on a ascale of 1 to 10, how difficult is it to install a aftermarket intake manifold?

edit: oh yea and what tools would i need besides hand tools?

THANKS

it's not a hard job at all, all you need to do is unbolt the stock one and bolt yours in place. you may think of replacing both gasket while you're at it. oh and be aware if your car is pretty old it could be all rusty and a bit hard to unbolt. if so, put some lubrifiant (rust cleaner, cant get the name of it) on each screws then they will be much easier to unbolt. hope this help, tho im not a mecanic, only speaking of personnal experience ;)

cool,,, can i expect any performance gains from this?

i doubt that you could notice any power increase while driving, but headers are a beginning....when you will get a cat back system and cold air intake, and some mods, you will certainly notice a difference.

headers wont do much alone, thats my point

wait a sec. what year is your car? Its super easy if you have a carb and manifold setup, but if you have fuel injection you are looking at some serious time spent in disconnecting hoses cables brakets etc. Depending on your setup now and what you are planning to get, you may gain some difference in performance, but probably not hugely noticable. Tools will vary depending on what your taking the manifold off of. For a carbuerated 350, one wrench, and a screw driver or two. For a tbi 350 various other tools to get off the linkage miscelanious hoses, etc.

Timber is correct, it depends a lot on the car.
For older domestic V8's the correct manifold will make a big difference, especially if you are changing the carb from a 2 bbl to a 4 bbl.
It's also easy to do.
Newer EFI stuff are much more integrated, that is, to really see the full potential of a new manifold, you should also change other things like exhaust, throttle body, ECM chip, etc, depending on the car.

BTW when you ask such questions, it really helps to tell us the make, model and year. Otherwise we are just guessing here.

just want to point that my answer was directed to a 4 cylinder car. (i didnt think about old V8s and stuff like that)

well if you check his profile, he drives a 2000 jeep wrangler
