You will need the explorer timing cover, but you can use the cobra intake. The explorer uses the gt40 intake. Using the entire explorer harness, both the dash and underhood, will operate as normal, Speedo and all. Make sure you grab the G force transducer located on the driver side framerail under the seat area, as this is for speedometer operation. By swapping harnesses, you will gain power windows/locks, cruise, and any other option your donor has. You don't have to install the power windows & locks if you don't want them, but they are a nice luxury. When you remove the cps (cam position sensor) and cam syncronizer (replaces the dizzy), bring #1 TDC before you remove the syncronizer, pull the cps and take not which way the syncronizer is pointing, as this is crucial for proper timing. I recommend marking the syncro housing with a marker where it went. If you choose to purchase a new syncro, get the one from rock auto, its cheaper and comes with the installation tool. You also might want to get a tuner so you can pull in all the power and mpg available, as well as delete the auto tranny if you go with a manual...
