Part of the point is to keep my car relatively how it is (no weight reductions, aero), and not to spend much money in order to save money, outside of regular maintenance like plugs/filter/wires.
Speaking of wires... I've realized that the wires I bought in late 2009 are pieces of sh*t. They're Xact brand, and one is arcing to the head at low RPMs, and another one is pretty loose on the spark plug. Google search yielded a LOT of bad reviews. They're under "limited lifetime warranty" from Advance, so I'll either try and get a new set, or just drop $60 on some Bosch wires I found on Amazon. Somehow I paid $120 for these current wires and I can't remember why I didn't price shop, or check reviews on the brand.
