I keep a clean engine bay. Now it's at 80k and I've performed all applicable maintenance on the engine and suspension; New water pump, flush coolant, new 12mm ignition wires, new fuel filter every 20k, bosch platinum 4 spark plugs, AEM Ram air intake, new battery, new belt tensioner and serpentine belt, all fluids topped off, regular oil changes w/Valvoline Purolator filters. Run fuel injector cleaner through the system every 3000 miles w/oil change, and tire rotation. New brake drums in back, discs in front, new shoes all around. New struts all around 2k ago. Strut tower bracer, and new rims and tires to top it all off.
