30lb MAF

These MAFs aren't like the old fox bodies. You can choose a more capable MAF or stay with stock, depending on the power levels of the engine after your modifications. You will have to have a hand held tuner and tune the MAF (new or stock) to play nice with the new injectors and engine air needs. I take mine to a reputable tuner for such tuning on a dyno but there are some guys that do their own tuning. I don't computer that well.
