3.5 tune up
 

So my montero finally hit 100k, last time I did a major tune was back it had 75K I had the timing belt replaced along with the water pump. I do my own oil changes, coolant change, things like that but now its time to get the whole package going. What am i going to need? what are the correct spark plugs? what should i look for? the spark plug wires look great, should i replace them? its a 2001 montero xlt its pretty much stock all the way around.

I would say most often overlooked is the fuel filter. If your car has one, you should be changing it every 60k, and the same with your PCV valve.

Go to Autozone and they'll tell you every single spark plug that'll work in your car. Just stick with the NGK coppers, they are the cheapest and they are awesome. Replacing the spark plug wires would probably be a good start too.

Air filter?
