i have an 01 ranger. i have a drop in k&n, bosch platinum 4's and i did the airbox plastic tube removal. im buying a gibson side swept cat back from someone on here, and i was looking at getting the roush cai. would i notice any difference? i was also looking at getting the sreaming demon coil pack, and plugs and wires. i was wondering if i did that, what would be my best bet for the plugs/wires, and would that give me any difference. and lastly i was thinking of buying the pulleys for my truck. i was just wondering what all that would do for me. im not doing it all at once.
thanks for the help.
