Your Lincoln was designed by Ford to be nice and quiet. Unfortunetly this is bad for power. You may notice the intake tube from the throttle body to the air cleaner has a narrow place in it. This helps speed the air flow at low RPM's but it also reduces engine noise. It also restricts airflow at high RPM's. To remedy this you should install an intake hose from a 86-88 Mustang. This works if you keep the stock air filter. For the ultimate (and cheap), at home cold induction you need to ditch the stock intake pipe and air filter box. You will need the following items:

1. 26 inch universal fit intake hose (about $7 at AutoZone. Looks like the hose on the back of a clothes dryer) 3 inches in diameter.

2. A conical filter with a 3 inch opening. (I prefer K&N. Either the 7 inch or 9 inch filter will fit. $40.00 at NOPI)

3. 2 hose clamps (3 inch diameter) $0.50 each

Total cost: about $50

Tools: Screwdriver, maybe socket set it you strip a screw head

First, you should have removed you air box. (see Air Box Removal) Remove the stock intake hose from the throttle body. Take your new hose and clamp and immediatly put it on the throttle body. (You never know what may fall in there) The hose may be a little large but that is ok. Clamp it down good. Now take your nice, big conical filter and slip it inside the fender well. You may need a friend to hold it from under the car. Position it where the old air box used to sit. Slip the hose OVER the opening on the filter and clamp it down good. The filter is only held in place by the hose, so make sure the clamp is holding good. I have had no problems so far with the filter coming off (even after some pretty rought rides). Congratulations, you now have nice, cool air flowing freely into your engine. It will sound better when you stomp the gas too. Total cost: about $50.
