I've only had the truck a short time and I really don't know anything about its service history. I'm going through easy stuff that I can do myself as I get time. Oil was pretty dirty, auto trans fluid is as well but I think I'll take that and get it flushed.

Anyone have recommendations for plugs and wires?

I'm more interested (maybe 70/30) in mpg that performance and don't want any radio noise.

Feel free to point me to an existing thread, I don't seem to be driving the Search function very well.

Thanks,
-Jeff

Replacing your plugs and wires depends on your mileage. I replace my plugs at 75K or so and use factory plugs. The wires, I'll push to 125K and replace them w/a factory set. Don't forget the timing belt that's due at 105K, although others have gone further it might not be worth the risk.
Change the oil and use synthetic w/a quality filter. The tranny I wouldn't put on a flush machine. I'd disconnect the line from the tranny at the radiator, start the engine for a minute or two and let the tranny flush itself out, about 4 quarts at a time. Do it 3 or 4 times and you've got 90% synthetic in there (Amsoil's great for trannies).
Might as well change the rear diff. while you're at it. Again, Amsoil, w/an additive if you've got a posi (do both rear wheels turn the same direction when you've got it jacked up at the pumpkin? That's a posi.) Wheels turn different directions, you've got an open diff. Flush the cooling system while you've got the giant catch pan out.

Ditto on the factory specified NGK plugs. Either factory wires, or take a chance on NGK or Denso replacements from Spark plug, Spark plug wire, spark plug gap, spark plug cross reference and ignition wires at Sparkplugs.com

I would replace the distributor cap and rotor, air filter, fuel filter, etc with OEM parts as well. I buy all of my OEM stuff through Nissan Parts - Everythingnissan.com

Don't forget your differential oil and power steering fluid as well. I "turkey baster" flush my p/s fluid with M1 ATF at each oil change - but that's probably overkill.

Good luck!

I'm OEM for most my parts too. I order a bunch of things all together including oil filters.

I stepped up a bit on the spark plugs and went with NGK Iridiums. I have not replaced wires. Stock cap and rotor is made by Hitachi and can be found elsewhere.

Thanks

Thanks for the suggestions!

I got the truck with about 76,500 miles on it. Overall it's in really good shape but a pre-purchase inspection showed things like the fuel filter to be original, the belts overdue for a change and the fluids generally dirty. That and a few pulley-type noises to sort out.

As time and money allows I'll change some of these things out and feel better knowing where I'm at. I'm a little nervous about anything major - I did a little work on my old '89 F150 over the years, but it was a beater of a 3rd vehicle, where the Frontier is now the daily driver and I'd rather not strand it in the driveway, at least not until motorcycle season.

I think I'm definitely due for plugs but I'll look the wires over based on your comments. I'm looking forward to "plug #6" based on some posts I've read. :)

Thanks again,
-Jeff

I agree, NGK are the way to go.
I pulled my plugs, they looked good so I went one range colder.
from what I have read, a colder plug will increase fouling, but will help prevent spark knock. since I had no signs of fouling, I went a bit colder.

I didn't change my drive belts until I did my timing belt, about 115K. According to my dealer parts guy, the gas filter isn't really a filter. More like just a strainer. FYI

Well I got them done labor-free when someone smashed up the front end of the truck :-(

Since the body shop had the whole front off anyway they went ahead and replaced the belts. Another pre-inspection item was too much water in the radiator mix - that gets fixed when the radiator is smashed :)

NGK Iridium and NGK "blue color" wires work really well on my s/c truck. I even went one heat range cooler than stock.

About 10bux a plug!
Had em - tossed em, they are junk. My VG just didn't like em.

use OEM wires and plugs(NGK).

Plug #6 is easy, I dont know so many people are scared of it.
