    I was told anywhere from 1 to 5 horses depending on how dirty your old filter is.

    The stock hp for the 2.8 is like 140hp for an 86, 135 for an 87-88. DKOV has a cold air intake on his plus a 3.4L tdc, so your increase will not be that high. I think a K&N is about 1-5 hp.

    1-5 sounds right. Instead of going stock I measured the opening of the black rubber intake "tube" and bought a cone k&n filter and hose clamped it to the end. I installed the air temp sensor on the end of the filter. easy . It sure sounds good
