I was wondering what were the best maintenance items to put on L27'*
Not looking for the best, just decent quality stuff.
I have heard all these bad things about bosch so I guess I will not use their stuff.
Plugs: AC Delco ? Platinum or Regular Plugs?
Wires: Does it Matter?
O2 Sensor: I think I will be going with AC Delco on that.
PCV: Does it matter?
Air Filter Does it matter?
Oil Synthetic or Mix or Non (Car has 102K)
I plan on cleaning the throttle body soon as well.
What other cheap things are worth doing on this just to make it run better and get better MPG?

Do I need to use platinum plugs with this car?

Stock gap is on the sticker on top of the radiator. 0.060" for mine.
