I haven't found anything for the 2.4 yet. there are some kits out of korea and EU that fit the 2.0, though the engines are both classified as the theta ii. hopefully soon.
I am sure you could find one and make it fit , I have done it before on other cars I bet you could on the Forte as well. Have you checked out any European aftermarket companies? I am sure something is already available across the pond.I really hope K&N is hurrying up on a cold air intake...I got money burning in my pocket so I can buy one.
