I recently purchased an '87 5000cstq. I am interested in putting a cone filter on it but needed to know if it has a MAP(Manifold Absolute Pressure) sensor or a MAF(Mass Air Flow) sensor in order to be sure that a cone filter wouldnt disrupt anything. Also if anyone knows if this will work or not please give input.

I am also interested in putting a BOV on. Does the car have a stock bypass valve? If not would it be safe to put a bov on it? If so where is the stock bypass valve located.


Thanks for your time.
