POP charger comes from my 1997 Nissan Maxima, made by Stillen for turbocharged cars. They copied it from Jim Wolf. Basically a big velocity stack that goes from 5 inch diameter to 3" inch diameter. As to what POP means? lost in time and space.

On my Maxima it helped the mpg a little bit as the filter is just as restrictive as the buick. basically the car had more power so it did not have to down shift going up hills.

The plugs and wires helped a bunch.

After rereading the TB/MAF cleaning article I am thinking that might be part of my issue. I have a hunting idle at the moment. The wires and plugs cleaned up some of it. Plus replacing all the rubber hoses.

i also have a issue where the car cant make it up long hills at 75 without down shifting. One of the reasons I bought this car was that I figured that I would get at least 25mpg. So I need to fix this.

When you get it right, you'll hit 30mpg, and the car won't downshift over any hill. It'll just stay in OD and lay on the boost. (you need to add an aftermarket boost gauge, see Techinfo for that also)

Find your IAT yet? It'* down there. That'll have a big effect on MPG'* too. It'* reading hot air in the engine bay and retarding your timing like a bad dog.

Ok Will the other question would be your thoughts on using the rubber 3" elbow that I have attached right now?
The main reason that i was looking at trying to keep the stock accordion was because of engine flex. How much does the motor move back and forth?

I figured the motor moves a lot after my experience with my 90 and 91 buick regal

I also just realized looking at the gut your air box thread
http://www.bonnevilleclub.com/forum/...408&highlight=
that the Bonneville air box it MUCH better than the Buick park ave one.
but wait is the 92-95 airbox the same size?

The park Ave air box has maybe half of the volume of the Bonneville.

I will post a picture of the stock 95 series 1 l67 air box for the Park ave. It is REALLY restrictive compared to the Bonneville.

It'* a smaller box, and there'* nothing to gut. We know exactly what box you have.

The S1 motor moves more because it peaks it'* torque at a lower RPM than the S2. And alot more tq than the 90/91 regals.

92-95 L67 airboxes and 92-94 L27 airboxes are not as deep front to rear and have no baffles to gut out of them. 91 buicks are also the same box.

I jumped on ebay real quick. 92-95 looks like same box as the buick park ave.

has anyone used a 96 up air box after gutting it on a 92-95? It looks like a very solid air box once you gut it out.

I've seen both, and I see no advantage to the other box. In fact, if you have an ELC compressor located nearby, the other box won't even fit.

Yeah you can see th ELC compressor in the mid photo. the newer Bonneville air box should be better as it has more still air on the clean side of the filter.

Checked when I got home. the IAT was hanging down under the ELC by the tranny.

As I drove the car not sure I like the sound of the intake. It almost sounds like a loud steering pump, only above 3.5k rpm does it start to sound good. Even then it doesn't come close to sounding like my any of my prior cars with CAI kits

Pull the K&N filter off and put the stock air box back on with the IAT plugged into the stock airbox. Will have to drive it stock wise and see if the mileage improves.

Have to source out some 3.5" tubing and some sheet metal next to build a heat shield properly.

Try this:

And go through the hole where the charcoal (vapor recovery) canister is instead.

FWI FTW.
