Spark plug and wire question

I have looked up numerous threads on this and never found a good answer. I have the 98 2.7 so Im going have the wires. Yota shop has the NKG wires for 45.00 for set. Toyota parts deals has the OEM wires for 98.00. Are the OEM worth double? Also my manual gives me the choice between Denso and NKG. Are you guys running the cheaper plugs of each brand are do you run the iridium plugs. Truck has 186,000 and i just purchased it. I have to assume plugs, wires never been changed. Im going soak them overnight with creep oil. Are you guys changing out the two coil packs also?

does anyone have the OEM parts number for PCV valve.. Thanks in advance.

 

I just picked up a 98 2.7 as well and odered the new packs and coils you cant go wrong with either NGK or Denso and i did get the iridium plugs.

 

I prefer Denso in my trucks.
And NGK in my 2-stroke equipment.

 

Thanks for the parts list. That will save me some time.
