#1 of 1164 spoiler by tipsicobob Sep 08, 2001 (7:13 am)
I just installed a spoiler on my 2001 aurora. It came prepainted (white diamond) from sportwing.com. The color matched perfectly and it is of very high quality. It totally changes the appearance of the car and I get numerous questions from other Aurora owners. It was relatively easy to install.

It took me about an hour to install the spoiler. The instructions are very clear. The toughest part of the job is to make the outboard 2 attachments thru an access hole in the inner panel. Of course I dropped a screw between the inner and outer panel which I then had to painstakingly fish out with a magnet. If I had taken my time and used a magnetic nut driver to install the screw, it would not have fallen between the two panels. The rest is a piece of cake!
#4 of 1164 K&N Filtercharger by rjs200240 Nov 12, 2001 (1:12 pm)
Has anyone used a K&N air filter in their 4.0 Aurora? I was wondering if anyone had positive results (seat-of-the-pants or whatever) with it. I've used them on other cars with sucess but was wondering if the Aurora benefits from the breathing.   It looks like the filter is the same as on some 3.1/3.4/3.8 liter GM motors. This would make me think better breathing would help since the 4.0 probably gulps more air than the 6-bangers. The filter is definitely the same as on the 3.5 Aurora, although perhaps the 3.5 just gets more air than it needs...
#5 of 1164 Air suspensions for '95-'02's by rjs200240 Nov 14, 2001 (12:29 pm)
I noticed this company that makes a rear suspension add-on for Auroras. I don't know if anyone is interested in an air suspension for load-bolstering or anything, but I'll put it out there. http://airlift.r-catalog.com/listparts.asp?mmid=103181&fldnum=0&prod=3 Summit Racing has it for less than the price advertised by the manufacturer. I believe the 2001-2002 Aurora has a load-leveling rear of sorts, although I'm not sure how it works (not by air, I believe).

Most Oldsmobiles have had air suspension for quite a while. All Auroras do. My Toronado does. The 1985 Regency I used to have did. It's pretty common because they can offer a smoother ride without having the headlights point to the sky with a full load.
#7 of 1164 Hmm... by rjs200240 Nov 15, 2001 (6:11 am)
Is that the buzzing sound when the Aurora is started up? It comes from the rear. I just figured it was the ABS self-testing. Why is there no attachment from the air pump for inflating things? That would be rather handy. Odd that they use an air rear for the Aurora as it is supposed to be more sporty. Air suspensions are softer, and allow for level loading, however they don't provide much stability in cornering. Thanks for the info. I had no idea. I wondered how they offered a "load-leveling" rear. The owner's manual and brochures make no mention of how this is executed.

If the humming stops after a few seconds, you might also be hearing the fuel pump in the rear as they are now electric and almost always located in the gas tank.   Campo57 Replies to this message: bingey (Jul 18, 2004 2:37 pm)
#9 of 1164 More on supercharging/performance wringing by rjs200240 Nov 16, 2001 (6:23 am)
I'm jumping here from the main board:   Another difference between bolt-on superchargers and factory jobs is that the engine management is made to work with the charger. Most factory jobs have some means (through bleed-off or clutches on the blower) to essentially remove the boost in low-load conditions. This saves the constant stress on the engine of a boosted intake charge. If you've ever watched the boost gauge on a 3800 SC, it is usually around 0-1psi until you dig into it. Bolt-on superchargers usually have no way of doing this as the blower doesn't know if it's a light or heavy load without talking to the computer.   Another cheap way to get some extra performance would be to try replacing your platinum plugs with something better. Usually platinum plugs don't give optimal performance. If you don't mind changing/checking plugs more often, you might get a boost from some AC Delco Rapidfires or Split-fires and maybe a less restrictive air filter.
#10 of 1164 Air Suspension by tipsicobob Nov 19, 2001 (11:56 am)
The Aurora uses air shocks similar to millions of GM cars built over the last 30 years. It's very effective in that it not only levels the vehicle under load, but also raises the rear spring rate as the load goes up. The base suspension is tuned for the character of the car regardless of the air shocks--so there is no real inherent need to be floaty or mushy just because it has load leveling or air shocks.
