I have a 92 w/the 302 and here is what i did ,
it has dual tubes ,any home depot sells pvc pipe,dont buy and "y" adapters or any thing like that.
1)lose the airbox
2)go to home depot and buy a length of 1 1/2 pvc pipe(its very cheap) buy the "wedco " rubber sleeves in the same spot of the store.get a couple of pvc 90 degree turns.
3)pvc goes together like butter,it glues and you can get that a home depot also.
4)it is pretty simple run two new tubes attached to you intake tubes down along the drivers side of the radiator,buy two k and n filter cones and rock and roll,YOU HAVE DUAL INTAKE COLD AIR.
if you want to get cheap buy a "y" adapter at the end and only ONE
>- cone filter,and the cones i bought were 3" so at the bottom you can again buy a "wedco rubber adapter to go from the two sizes.be sure you get the filter out of the engine ,they want fresh cold air so let them have it!
the home depot stuff will run about $40.00 , the cones are where it gets pricey,but you can get "imitation " cones on ebay real cheap(like $5.00).
i did not get cheap ,if you want to be cheap with the cones why bother,i have k and n's and to answer your question
YES YOU WILL FEEL THE DIFFERENCE!,IT WILL BE MUCH LOUDER THAN STOCK WHEN YOU HIT THE PEDDLE,AND BE SURE TO EITHER BUY BLACK PVC OR PAINT THE WHITE STUFF,you dont want to open your hood and have every plumber on the block laughing,although this is cheap and works as good as any kit you can buy.
BEST OF LUCK!
