What are the best parts off the parts house shelf (toyota or aftermarket) for a tune up i.e. plugs, wires, air filter, etc. Part numbers as well if you have them available. Mine is a '98 4 runner with the 2.7 liter 4 banger, automatic tranny, two wheel drive. Pretty boring really but it still runs pretty good - just starting to consistently miss at idle, and mileage is off a bit - all after 96000 miles. It's been approximatelly 42000 since last tune up parts were installed. Any help would be greatly appreciated...

The best parts are Denso or NGK. Don't use Bosch in Toyota engines.

For plugs I would buy Denso K16R-U as a standard plug or Denso SK16PR-F8 if you plan on keeping the truck for a while. The SK16 cost $12 each vs $2.40 for the standard plugs, but they will last a long time. Probably for the life of the truck. A medium priced Denso is PK16R8 at $6.90.

The NGK equivalents are BKR5ES at $2.40 or BKR5EGP at $3.15 or BKR5EIX at $7.80.
I have no preference between these brands.

NGK TX67 is a good set of plug wires at $43.

For air filters, I prefer ACDelco (part no A1232C, $25) or Purolator (part no A24645, $25). I would replace the air filter more often that every 40K.

Change PCV valve also. ACDelco part no 214-2002 or Purolator part no. PV1038

Prices are from sparkplugs.com or manufacturer

Don't forget the fuel filter. I also used OEM for filters like that. I am sure there are equally comparable aftermarket filters available though.

If you want OEM parts, 1sttoyotaparts.com and partznet.com are 2 Toyota dealers that sell online at a good discount.
