I have a 2004 Malibu LS with a 3.5 v6 and I'm not really sure where to start with performance upgrades other than a cold air intake. I've looked around a bit and can't seem to find much of anything. Is there some place I should look that I've been missing or mods for other cars that would fit mine?

If you've got the traditional box-filter, when you take it out, see that hole in the bottom? Follow it around, and you'll find out the FACTORY setup is a cold air intake.

Before I ruined that by putting a cone in the engine bay (where it becomes a HAI), I'd consider swapping to the OEM fit K&N or some alternative to that.

Keeps the original cold air, reduces restriction, improves air flow ... what's not to like?

Also keeps the car closer to box-stock for those pesky "emissions tests" aka "Boy, you can't just do ANYTHING to this car! We're gonna impound it and take your license!" some areas have ...

You really can't do anything to those cars but a CAI....
