Most of the following items can be bought at your local parts store or speed shop for around $50. The K&N filter is going to be 80% of that cost. You will need to buy a K&N filter (RE-0870) 9 inch conical air filter (or one of similar size and shape), a 2 to 3 foot long and 4 to 4.5 inch wide flexible hose (Mighty Flow brand intake ducting (part# 96074) works very well), two 4 inch clamps, a 1 inch clamp, and a small Fram (or other brand) crankcase filter. If the K&N filter includes its own clamp, then you only need to buy one 4 inch clamp. If you can't find any type of intake ducting hose, you can use flexible hosing like that on your clothes dryer, but this type of hose isn't too rigid and can be easily crushed by the hood. Plus it's difficult to clamp since it's relatively soft. Installation on the 1993 cars is going to be a little tricky. Since the 93's are speed density, they don't have a Mass Air Flow (MAF) sensor (like the 94+) which connects your intake hose to the rubber snorkel/elbow going into the throttle body. You'll need to find an INFLEXIBLE piece of tube or hose with the same 4" - 4.5" diameter which you can clamp the intake hose and rubber snorkel/elbow to, thereby connecting the two. A piece of PCV pipe will work. Or you can saw off the end of the stock intake piece (which you are removing), and use that as your connection. The 94's and later make use of the existing MAF sensor, so there's no need to find an extra connecting piece. On those cars with MAF sensors, use the rubber gasket that's on the stock intake piece (which you are removing) by putting it around the MAF. Then put your new flexible hose onto that. It increases the diameter of the MAF from about 3.5" to about 4" which helps the hose fit nice and snug. Simply clamp the K&N filter onto the new flexible intake hose and drop it down through the hole that the stock intake piece was sitting in. Then connect the other end of intake hose to the MAF (or your make-shift pipe piece for the 93's). Everything should just lay snuggly in place. The last step is to clamp the small crankcase filter to the air pump hose (which was originally connected to the stock intake piece). Then you're set to go.
