i just bought my 03 evo viii and i believe it needs a full tune-up. it has 45K miles and i dont think it has ever been done. does it need to be done and if so, what should i do? plugs, wires, fluids, all of them? none of them? something else? help me...... also it came with a injen intake system that needs a good cleaning and a greddy blowoff valve that i had to take off b/c i guess it was letting out too much air. would putting that back on with a turbo back stop that?

 

Any time you buy a used car, change everything. You never know what the previous owner did or didn't do. Then if you have any issues in the near future, you will know for sure what has been done and what hasn't.

 

Just do a 30k service:
Accessory belt, fluids, spark plugs, spark plug wires, coolant..Also when in doubt check owners manual

 

Make sure you use diaqueen lsd gear oil in the rear diff and tranfer case, it has been my (and many others) experience that any other gear lube will damage those systems. It is expensive, but you can do quite a few changes with one can.
