I just bought a very clean 1999 Mustang Cobra Convertible, triple black car.....very nice, but bone stock. I plan on driving it daily, so I want reliable mods. I changed to oil over to Mobil1 synthetic oil. I already ordered and am having a full Bassani exhaust, including new high flow cats, cross over pipe and 2.5" muffler system. I also plan on a K&N filter upgrade or some sort of CAI. Is changing the throttle body worth the $$$? I will also go to 3.73 or 4.11 gears when money allows, seems they are expensive to change...cheap enough to buy but time consuming to install.
What other mods give the most bang for the buck. I am not interested in a blower or supercharger.
thanks,
