Welcome to BITOG !
For your vehicle, in order of importance, I would recommend :
1. Transmission Fluid Exchange ( 3 x drain and fill OR flush via cooler line method ). For fluid, my choice would be Maxlife ATF, Honda DW-1 OR Castrol Import Vehicle ATF. There are many other fluids also compatible but these three are the easiest to find and are relatively well priced.
2. Brake Fluid Exchange ( Honda recommends every 36 mnths regardless of mileage )
3. Power Steering Fluid Exchange ( use turkey baster method with Genuine Honda/Acura PSF ONLY ! Honda P/S racks are unique and leak when almost any other PSF is used. )
4. Spark Plugs ( I recommend NGK or Denso Iridium plugs. Check websites for the correct part# for your make and model )
5. Run a bottle of Redline SI-1 or Chevron Techron with a full tank of gas till almost empty to clean your Fuel System out.
6. I assume you have kept up with the filters/brakes so far. If not, I recommend a visual inspection to make sure these parts are in healthy conditions.
7. If you have a V6 model, you should now start saving for a timing belt service which will be due at 100k~105k. When you do get around to getting this done, make sure a complete kit is installed. Kits come with all new belt, water pump, bearings and tensioners. Getting these replaced at the same time saves ALOT of labor were these parts ever to fail. Replacing the drive belts would not be a bad idea as well. Head over to RockAuto.com if you have someone reliable who can perform these svcs.
8. Coolant flush ( should be done after a timing belt/water pump replacement )
9. I agree with others here. If you do 4k mile oci, I higly suggest switching from PU or M1 EP to a higly regarded conventional or syn blend oil like Mobil Super 5000 OR Pennzoil Yellow Bottle or Valvoline Maxlife. You will save a considerable amount of cash with almost no difference in performance/wear ( I say almost because wear is always going to change with a switch in oil. Usually in miniscule amounts). It might even get better, I certainly dont see it getting worse.
