Tight on a budget? We all are. Some guys here might think this is going to be 'really budget tight', but here's what I did for my first mod.
1- 'universal' SPECTRE short ram intake. 40 bucks.
1- SPECTRE dual cone filter. 20 bucks.
1- 3" to 2.5" rubber coupler. 10 bucks.
That's 70 bucks for a short ram, parts available at Autozone.
Don't ask anyone to help you there, cuz they won't know WTF is going on.
Take the 'universal tube', and cut 6" off the long end with a hacksaw. Cut 1/2" off the short side by the bend. Make sure you cut these straight. Follow the directions given in the kit about cutting, it works. File down the edge, and run a big rag thru the tube a couple times to make damn good and sure you cleaned out all the aluminum shavings, and dust.
Now, fit the 3 to 2.5" coupler on the short side of the bend, and stuff it on the throttle body. The long part of the tube should slightly turn down, almost pointing to the cold air intake hole in the fender wall. There are 2 pieces of aluminum plate that comes with the kit, to stabilize the tube. I bent the short piece enough to cradle the bottom of the tube, and bolted it with one of the three original intake box screws, to the inside bolt hole of the original fender wall bracket. To keep the squeaking, and friction of 2 pieces of aluminum rubbing to a minimum, I stuck heavy duty felt padding (maybe 5 bucks, the kind you put on bottom of chair legs) to the top of the bent stabilizer bracket. Put the Cone filter on, but don't tighten nothing down yet.
There is a hole on the 'universal' tube by the small welded breather vent tube. This is for your air sensor, which you'll have to cut out of the stock rubber intake hose. Be careful with this piece. It is glued in, so you can basically just slowly pry it out with a small screwdriver. BE PATIENT, you don't want to break this thing! Once it's out, you'll notice it is square at the base. I cut/filed the square edges down until it fit in the hole. Insert the air sensor into the hole, making sure all the 'honeycomb' style square holes toward the end of the piece can receive free flowing air to the sensor( front to back, not up and down). Use a bead of RVT, or silicone gasket maker sparingly to hold it in the hole(make it look like a smooth weld). Wait until it's dry to plug the wiring in. Basically, you're finished. Tighten up the filter, and the rubber coupler. There is enough room in front of the cone to run an additional piece of flex tubing to the stock cold air intake hole( if you want that), but you DO need the DUAL CONE filter to do this.
Unplug your battery at the ground terminal while the RVT silicone is drying(I let mine dry overnight.). This will allow your computer to make its air/fuel adjustments on a clean slate, then plug in your air sensor wiring, and reconnect the battery. Upon first turnover, you won't notice much difference, until you put your foot in the gas pedal. Quite an aggressive sound, from a simple intake! Big improvement overall, especially out of 2nd and 3rd gear. 4th gear has better bottom end, also.
For 75-80 bucks, and a little time, you will NOT be disappointed. Apologies to all you guys who hate the word 'UNIVERSAL', but this thing works! Another fine American tuner project from SHADY GARAGE.
