Follow these instructions carefully to ensure correct fitment and operation.

Step 1: Disconnect the negative battery terminal.

Step 2: Remove the entire stock air inlet system from the vehicle, this is easily done by removing the hose clamp at the throttle body, the two mass-air mounting bracket bolts from the strut tower/inner fender well area, and the two filter box mounting nuts at the top edge of the factory box.  

Step 3: Remove the air injection tubes from the passenger side. NOTE!!! On 1994-1995 models, remove the steel EGR Tube mounted on the passenger side header, kit 1525 and 15250 include a new EGR Tube Assembly.  

Step 4: Remove the spark plugs and spark plug wires from the vehicle.  

Step 5: Working from under the vehicle, remove the nuts connecting the H-Pipes to the factory exhaust manifolds and the nuts holding the mufflers to the H-Pipe and slide back a few inches for clearance.  

Step 6: Remove the stock exhaust manifolds and clean any gasket material from the heads. (Header removal and installation is done at the top of the engine compartment).  

Step 7: Using the gaskets provided start all the new header bolts before tightening the new headers.  

Step 8: Reverse the previous steps to complete the installation.
