Q: 1996 Peugeot 306 2dr Auto 1.8L
A: Since it's an automatic you'll have a hard time benefiting from upgrades of any type. Personally I'd just go to google.com and search Peugeot 306 Performance Parts....you'll find someone who sells parts for those. Obviously, starting with an Intake System, Header, Catback Exhaust System are the most common upgrades for cars like that. Good luck!
