1999 limited T&C 3.8 Tune up questions

What should I replace for a good tune on this van. It runs great, but has 177000 mile on it and I want it to stay in tip-top condition.

Thanks in advance, PS it has been about 2 years since I have replaced anything.

Change the plugs and wires.Stay away from Bosch for spark plugs,Chrysler products run like crap with them install and put in Champions.Do not get plug wires from AutoZone or Advanced,they sell the cheapest plugwires out there and you will have problems with them a lot.You do not have to change the fuel filter,it is in the tank part of the fuel pump.Check on this just in case.
