3. Remove the stock intake from the throttle body to the air box.
4. Remove the stock MAF sensor from the stock air box and install into the JLT MAF housing using the supplied MAF screws.
5. Install rubber elbow onto end of JLT MAF housing as shown.
6. Install the JLT filter onto the MAF housing. You want the filter to be installed fully onto the MAF housing. This means it may slightly overlap the MAF sensor. Tighten clamp snug.
7. Install JLT intake onto the throttle body. Remove the stock PCV hose from the valve cover and use the supplied hose to connect the PCV to the JLT.
8. Check to see if your upper radiator hose clamp is pointed up. If so, using pliers, rotate to the right to help clear the heat shield. Install JLT heat shield onto your truck using the supplied bolts. Slide it under the filter and into position under the MAF housing just under the MAF sensor area. Use the forward most mounting holes for the stock air box.
9. Plug in the MAF sensor and intake install is complete.
