you might have not stock heads since you are sort of new to this, make sure they are e7's, if so, some porting would help ALOT, or just buy some cheap gt-40's like i did, the cam would work with the airflow and probaly be the best thing you could do for that car, even with stock intake, the cobra intake wont gain anything near what heads, or head work would do.
