Spark Plugs

[mvy]

My 2000 LX470 getting a new timing belt and water pump now at 115K. The dealer mentioned platinum spark plugs for $350. Wow.

The car runs fine, can I wait?

Can I add these myself?

The spark plugs are to be changed at 120K miles. Mine were still fine at that point. You don't want platinum plugs, get the proper iridium plugs from Denso that have the 0.7 mm tip. These are the ones that last 120K miles. The platinum plugs last 60K miles and so do the 0.4 mm iridium tip plugs. It is not hard to change the plugs. You can get the Denso plugs from Toyota (Land Cruiser), Lexus, or from an auto parts store. The 0.7 mm ones cost about $10-15 each, depending on the store. The 0.4 mm is a performance plug and usually costs less (less quantity of expensive iridium in it).
