Hi I will be doing a oil change soon and I was thinking of putting in new spark plugs, 180 themostat, and new air filters and possibly some decent spark plug wires and is there anything else you recommend that is cheaper ( under 100 bucks ) and easier to install that i should save up for? I know that these wont do anything to special for my car but its just to get started modding her. Or should I just save up for a magnaflow exhuast other then buying new plug wires and other stuff? Its for a 87 iroc 305tpi/auto. Thanks.
