But...my hood hinge may be higher than yours... I thought most 3rd genners do that on purpose..to "cowl" the heat out a bit...
But even then, I know there's a lot of clearance...

Champion copper plugs are pretty short as well as the Bosch Platinum Plus 4's - no cutting... I don't know they are worth the money, but they are short plugs...I'd rather pay .69 cents for Champion coppers than $5 a plug for the Plus 4's...too late.

Those look to be the Made For You ones(I got mine from Summit). I have them and am using Taylor plug wires. It really is a btter way to have the wires run.

Your car will never go into closed loop and therefore you will be running rich and have very crappy gas milage. Unless of course your referring to rear oxygen sensors, they aren't necessary.

we don't have emissions in indy. from what my paper work says it is the rear o2 sensors. where are these located? the only ones i know are the ones on the headers.

Very easy to make and they come in super long lengths. You have to buy the over the valve cover looms (with bolts) yourself, but every place sells stuff like that in different colors (blue) too!
Your arm will be in pain from all the crimping, but it's worth it and makes the engine compartment look clean and gives you more options if you run long tubes and you do not want your wires touching the runners...

Z91Bowtie...I can't find the list but some things I do remember:
None of the following are on:
A.I.R. Pump
HVAC
4L60E
Steering pressure switch
I'll try and scan it when I get time to see what is and isn't on. It's been a long time since I even looked at it and my computer in the garage may not even have the correct software for it on there anymore.
