    112-509 is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Works as good as it looks Very satisfied with the design of the product. Parts and sensors swap easily with the original throttle body which makes it a no hassle upgrade. It is heavier than the stock version but it's well worth the added airflow and strength of the part. I bought this for my 94 Camaro and plan to install a procharger, so the billet construction makes it more reliable for this application. The only issue is that the screws holes are more shallow than the stock throttle body so the screw on the top left corner will be up against a sensor. To fix this you can either chip a piece of the sensor off, shorten the end of the screw or add more washers to the screw. If you're using the original intake with this size throttle body you're going to have to bore out the holes to match the throttle body.

    how much HP does it ad to a 95 Z28 LT1 stock engine

    Asked by: crash6969
    It will depend on other modifications, this will provide more airflow if the engine has been modified.
