I bought a 99 Gs300 with 57K. It has now 62K. When should I change the spark Plugs and what kind of plugs and wires should I use. I dont want to compramise gas mileage for extra power.

 

No hits? I heard 2001 have spark plugs good till 100K but mine is a 99. What spark plugs do I need? Are they pregapped? Can I put the ones from the 2001 into mine so I wont have to change them for another 100K? What are they?

 

Spark plugs have been covered many times on this forum for all vehicles.
