I've got one of those $50 advanced auto parts coupons, but dont know what should I do with it if anything?

the car is a 2000 v6 camaro with 101,000 miles, it has never broken down, I want to keep it that way,

the maintainence is totaly up to date, i've done all the mods I want, all filters & fluids are new, & it runs good, just replaced alternator, cat, PS pump, ICV, MAD sensor is cleaned reguraly, battery, plugs & wires,

was thinking of getting one of these..., they are all orginal on the car.
NewCoils
EGR valve
starter
AirConditioner pump
Fuel Pressure Sensor?
or something else???


What is most the common to break? I want to prevent having a break down if possible. Else I would just let this coupon expire and wait for the next thing to go out.

 

I think I want to replace the fuel pressure regulator....but i found out how much work it was so i wont bother

Definitley egr valve or invest seriously in a k&n filter. U can clean the egr though so u might not need to change it. U might want to change the fuel filter too if you havnt already. The k&n filter is a real good idea not cause u want performance but the car will be able to breathe so much better hence less load on the engine and better fuel economy. Also, DEFINITELY run synthetic motor oil if you are not already.
