The spark plugs have absolutely nothing at all whatsoever to do with boost levels.

However; change them anyway because new plugs are always better. In the GTP, don't use the iridium plugs, use copper core. I highly recommend Autolite 605's, gap them to .055"

In the GTP, spark knock is a common, performance robbing issue because of the supercharging. You'll lose 5-6 horsepower for every degree of timing ****** that the engine computer will employ to prevent the spark knock. If you use copper core plugs though, this problem will be less likely because copper dissipates the residual heat much faster than iridium, so that only the electrode spark alone can be hot enough to ignite the fuel. The only other difference between the plug types is how long they last. Iridium plugs were the originals only because they last longer...they offer no performance benefit to the GTP.

Now on to your actual question.

There only a few causes for loss of boost pressure in the GTP, all of which are an easy fix.

Supercharger belt slip, disconnected or damaged boost bypass valve hoses, or maladjusted boost bypass valve linkage.

The easiest thing to do first is the boost bypass valve adjustment. This will produce results even if you DO still have belt slip or a leaking hose.

Locate your boost bypass valve. You will find it mounted directly in front of where the throttle body bolts into the intake plenum.
You will see that it is held in place by three bolts. Loosen them in this order; left, right and rear. You will find that you'll need a 4" extension socket to reach the rear one. Hold your socket on that one while you push down on the valve body. As you may notice the mounting bolt holes are elliptical, allowing for the height adjustment. You can use this as a visual reference for how far to push the valve down. You shouldn't push it down all the way, only about a half an inch will suffice.

What the adjustment does is reduces the amount of throttle opening needed to produce boost, by shortening the travel length of the valve lever that is attached to the throttle. When properly set, it will allow about 11 to 11.5 PSI at wide open throttle, or just short of wide open throttle. In any circumstance you may also notice that your GTP is a little quicker from a standing start after the adjustment.

Hi, Very carefully. You'll have to get on top of the engine to remove the back plugs.
Just take your shoes off when you do this so you don't break anything. Also prop the hood up so you can access the plugs better. Good luck.

Spark plugs, transmission fluid and coolant change, supercharger oil, air filter, fuel filter, tires, brakes, engine mounts, BTSI inspection and power steering fluid. Also inspect the belts, hoses, pulleys and look for wiring damage.

Anyone know the spark plug gap on a 1998 Grand Prix gtp? Is it .060?


Yes. On a stock 98 no less than .055" nor greater than .060", is acceptable.

There is no wastegate.

Change the spark plugs and pay special attention to the plug on bank 3. Look for physical damage on the electrode...cracked, bent etc.
Use Autolite 605's copper core gapped to .055" and NEVER run less than 92 octane.

Sounds like it is misfiring.
Try changing the spark plugs and you MUST run premium fuel.
