Wat u drive? .. Waja i suppose rite ? .. This model uses the mitsubishi engine 4G18 1.6EFI SOHC model and also the mitsubishi INVEC II Gearbox system.
The question u referring to also falls to some Lancer 1.6 (2002 Production). About the 4G18, you really need to take out the 2nd catalytic converter, the one right under the seats.
Also, adding racing air filters (cones) is out of the question, unless you add a cold air intake under the three inch sizes. The K&N mentioned above goes right in the stock box and out performs the cone shaped filters.
A road hugging 205/50/16 is suitable :)
Dont forget the grounding kit to improve electronics in ure car .. get it from our buddie huakenny .. :)
