lancer ralliart base cover different compare to lancer one.
lancer snorkel sit on the cover, while ralliart one not. so you need to cut it.
or you can buy the ralliart version cover too.but i think it will look weird cause our car dont have intercooler pipe. but it open hole as default and look neat and clean.

nope evo x snorkel different.
lancer ralliart is more like a lower grade evo , cut off  brembo brake and lower power etc, but still got 4wd system.
