Im building a mild LQ4 for a work truck that will see some moderate towing. All I plan to do as of now is add some lightly ported 243 heads, Comp Cams 212/218 LSx Cam "HIGH LIFT", long tube headers, a tune, and a good exhaust. This engine will never see 6000 rpms. Would adding an LS6 intake be worth the trouble, or will the factory one off my 04 LQ4 engine work well at the lower rpms I will be running?
