I have a 1998 grand prix 2 door gt 3800 II. I want know about some basic moods, like the dog bone flip, or what mm plug wires would be best. The only moods I've done to it is a ram air intake and a risitor chip in the IAT, but I dont even know if the risitor is junk or not cause i cant tell in hp or mpg because my odometer is broken. But please feel free to leave any advice you can thanks!!!
 


To flip the dog bones, used lots of WD40 and a ratchet on each side.

For plug wires, buy some stock Spark Plug Wires from your local Auto Parts store, but if you want "aftermarket" ones, get MSD 8.5mm or PRJ wires.
 
If you have something to grind it down with, the L36's lower intake is a pretty bad casting which could use some opening up. When you do that you could update your LIM gaskets to the new metals ones if you haven't already. Sadly for the N/A there isn't much you could do for cheap that will make it quick while still being N/A.
 
I know it sucks i'm going to do a top end swap when i have money and all the parts but that dog bone flip is a good mod didnt think it would change my car that much but wow i was wrong haha
