Sorry for rushing but I need the order ASAP
Thanks
Shawn
Looking at the coils from the front of my Aurora, the spark plug order is:
6 7 4 1 8 3 2 5
These numbers are printed on the top of the coils on my '97. Replacement coils do not have the numbers.
Good luck.

Greg, I also got the mounting plate; I'll probably enlarge it myself (from 78mm to 80mm). I went a bit crazy and ordered two of these from my favorite Olds dealer; they're only $10 each discounted.
My initial investigation of the intake manifold is that there is not much that can be done to increase airflow. There are some small ridges -- casting parting lines I think -- that maybe could be smoothed out. But physical access to all but the first one will be very difficult.
Awhile back I suggested bypassing the throttle-body coolant lines during warm weather to achieve higher performance. Now that I understand the plumbing, this is much easier done than I expected. The coolant inlet to the throttle body is a ~5/16" hose that comes from the water pump next to the outlet that goes to the top of the radiator. The coolant flows through and heats the throttle body, then exits to the surge tank, again with a ~5/16" (I haven't taken one off to measure it exactly yet) hose. It will be very easy to run a hose straight from the water pump outlet to the surge tank inlet; probably be a good idea to cap off the throttle body circuit to prevent corrosion.
This stock connection surprised me as I had considered the surge tank as pretty much the same as the old coolant recovery tanks. But the surge tank has the pressurized cap that used to sit on top of the radiator, and it looks like the arrangement with the throttle-body coolant path ensures a constant flow of coolant through the surge tank.
blk97aurora-Congrats on your ebay purchase! The TB #'s matching is great. I've been thinking about just boreing out the mounting plate myself too, little saturday project. What where you refuring to about getting two at $10? Mounting plates? I'll buy the extra! Congrats again, you'll enjoy the extra ponies from all of this. I know I do. IF you don't mind me asking, what was your final bid for everything of the 96'eldo?
I'd send the TB and get it done. Then, if you do the plenum yourself, you can hold it up to the TB (I' use the bolts to for an exact fit) to see how you are doing. It sure seems like a messy job though. RSM will do it for $100. I then sanded mine with a sanding sponge to make it smoother.
Idea - you can cut yourself an 80mm gauge out of something (small stick of wood or metal) or maybe an actual disk. I guess nice thick construction paper would even work. Slide that into the plenum to catch any high spots that need more work.
I kind of wonder about the coolant through the TB. The air is there for such a small fraction of a second, I can't see that it matters one way or the other. I can't see the air being heated much. I think disconnecting it would be an improvement though. I'll bet it would run fine in the winter as well.
Thanks for the manifold info!
Yes, theb $10 part I referred to is the F-SPACER (that's what the parts catalog lists it as). I haven't received my parts (I ordered gaskets, too) yet from my Olds dealer -- they're still on backorder. I decided to buy the extra spacer just in case I screw up enlarging one from 78mm to 80mm. I'll keep you in mind.
I went for the $150 buy-it-now because I did not want to get into a bidding war. I think that wasn't bad for all I received since a TB by itself went for $93 a few days before.
I disagree with you about enlarging the TB spacer from 78mm to 80mm being a messy job. The way I see it, there is only 1 silly mm to remove from the inner circumference of the spacer. The longitudinal distance is also small since the spacer opens up to greater than 80mm shortly downstream from the TB gasket. Once I try it, I may change my mind and tell you I should have paid $100 to RSM. I'll let you know.
I believe that the TB coolant line is there to warm the inlet air when the engine is cold to improve driveability. It is also there to prevent icing as described. The unwanted side-effect is unneeded heating of inlet air after the engine is up to operating temperature. The old exhaust manifold heaters had a mechanism to turn them off after things warmed up. Our TB coolant line has no such mechanism.
It's true that the air flows through quickly. But I think it is not accurate to believe it will not absorb heat. After all, that's the way radiators, a/c condensers, heater cores, and turbocharger heat exchangers work; admittedly, they have more surface area for heat transfer.
TB-By-Bass I totally agree that under our hoods is an oven. Although the TB dosen't get too hot to touch, Greg and I dynoed than swaped them. It was pretty warm though. The incoming air flowing through at fractions of a second has to be warming the air some. Just like radiators/turbos and everything else blk97 said. I don't see any problems with the by-pass during warm weather. I'll rig something. It's very common mod for many tuners.
Draw your own conclusions.
rjs200240: I agree the STS should eat more gas. My old Aurora had the 3.48:1 axle and could get near 30 on long highway trips. The SLS is now averaging about 23.5 but I now live out of town and to and from work is nearly all highway.
There is a mods board which isn't too full and should be good reading (couple hundred posts vs the thousands here). Welcome!

They posted some stuff I've done on my 98 Aurora regarding airbox mods and throttle body work. It includes pictures and dyno graphs too. Several guys here have made some good modifications.
I was washing my car today when one of the neighbors stopped by (to ask if I washed cars for a living as I'm always doing it). She commented on how nice my car looked and then said "is that a Toyota Aurora?". I told her it wasn't but to try to guess who made it. She guessed Acura next, then Infiniti. She was a bit surprised when I mentioned it was an Oldsmobile. It's a real shame most people wouldn't even know where to go to buy one if they were interested in it... I know most of the Olds models aren't going to be passed on to other lineups, and here's to hoping their marketing isn't passed on to anyone inside GM either...
How can GM be finished with the buildout of the Aurora when they specifically say on the OLDS website that they will build the last ones in MAY 2003? According to the article, they have finished the buildout 2 months early. Also, from what I have seen on the OLDS website, they did not do that with the Intrigue. They built the last one on June (14) 2002 as they said.
The reason I question this is because I am working on purchasing a Collector's Edition and wanted to order one of the last few if possible. I have a deposit down with a dealer for one and they have said nothing about this. Basically, I am questioning the validity of the article.
If it is true, I am going to be one highly ticked off customer!!!
Thanks for any insight anyone can give about this to alleviate my fears and anger.
B.T.
Remember, it can take upwards of a month for a car to make it from a factory to the dealership (though, in the above case, it's only an hour or so drive). I would go to the dealership where you placed your deposit and ask them to put in writing that they're getting a Final 500, and their estimated delivery date. They may want you to write up a sales contract. If they can't/won't give you this info, I'd suggest dealing with a different dealership. Where are you located? You might call Olds to see if they can refer you to a dealership that will get one of the 500's (I'm presuming that only a handful of Olds dealers will)...
Hope this helps,

There is also a link about "where to get one". That lists a bunch of dealers that are scheduled to get them. If yours isn't on there, you may want to at least look into it.
190 Auroras were produced this last week.
That is far more than 8-17 they were producing a week before they started the Final 500 production.
My dealer in Charleston, SC has a Final 500. Sharp looking car, especially with the cadillac wheels.
If your dealer can't tell you about the car it is clear he is not getting one. Go to another dealer because not every Olds dealer qualifies for one.
Looks like he is lying to you.
RJS- Is you car the same color as Final 500? My wife hated the color. She said that it was too dark and liked the red color on the Deville much better. I guess that is a hint for me.

When they built the last Reatta's (1991), they did not even begin production until they had all of the dealers orders in. Then they built about 2000 cars.
I sure hope GM will get a clue about advertising and promoting their cars - especially when they make a good one like the Aurora.
Hey - different subject, but any speculation if the Chevy SS concept car will make it to production? A very cool looking 4 door with a stroked LS1 for 430 HP. Too cool. That would be worth waiting for, although knowing GM, they would look at the GTO and figure they have to water down the SS performance so as to keep the hierarchy in place. It would probably suffer from this backwards thinking again. I doubt the interior would be anything as nice as an Aurora though, but it looks too cool, provides some nice room, and would melt the tires on command.
The Deville red is pretty cool because it is a pearlescent color, not metallic. It is like a red version of the White Diamond paint. It is a nice color, but looks sort of stupid on the Deville IMO. It looks a bit more appropriate on the Seville. It would probably look pretty good on the Aurora or CTS (I saw a CTS in the dark red a while back and it was really awesome looking. Unfortunately it also had some big ricey exhaust tips and Vogue tires that sort of ruined the overall look).
The car ran great, what a wonderful highway cruiser. When I was on the 2 lane and needed to pass, I just punched it and zoomed to 90mph in a flash. Love the sound of that V8 coming to life! Cruising San Diego and Vegas with the sunroof open taking in the warm breezes was awesome...up ahead in the distance...I saw a shimmering light...
She's got 85,000 miles on her now and people still think this '97 is a brand new car. Did I mention that I love my Aurora...you can check out any time you like...but you can never leeave!
