I have a 2001 Nissan Maxima, and i'm about to change the spark plugs. I have a Haynes manual, and it's telling me that I need to remove the cover on top that says V6 3000, and then to remove the intake manifold collector. My question is what is the intake manifold collector? Do I need to do anything special like disconnect anything that could hurt me, i.e. battery? Apparently the older cars were easier to do tune ups on. After the intake manifold collector, I think I have the spark plug job under control, just seemed kinda interesting to read about the IMC. Anyways, thanks for any help!
Changing spark plugs?
because th intake manifold collector overlaps the plugs them selves, that is why you have to remove that part. the only caution that i will give you is be very careful to mark where every thing went. you could be removing allot of wires. remember where all of the bolts went. disable the starter just to make sure, and use caution around the fuel system. it is not that difficult of an idea to do though. i did one years ago on gm 3.4 that was very similar in design really. just go step by step, you will do fine.
Changing spark plugs?
remove the negitave side of the battery cable the imc is the part between the intake and the air filter the reason it needs removed is the height between the plugs and the imc it just makes it easyer to access the plugs i always take a air hose and blow off the top of the engine before i start a tune up that way any loose junk wont fall in the cylinder good luck ooh if you have a cell phone with camera take a picture of engine before starting that might help when going back with things
Why? Is the IMC in the way?? According to this page, removal of the IMC is not required to access the spark plugs.

the collector is what separates all the intake air usually after the throttle body. Look at this pic and see the metal gray piece in the middle of the engine that looks like 6 hoses melted together thats it. http://www.turbo-kits.com/images/maxima_鈥?/a>
