It does matter where you buy spark plugs. Even if you buy the sparkplugs that are specified by Lexus, but you buy them elsewhere, you could be having problems.
Specifically, the sparkplugs that you buy from Lexus, are pre-gapped exactly for your car. If you buy the identical plug from some other place, the gap may not be right. You than will have to gap them properly yourself.
Never heard of that "vehicle specific gap". I always buy my spark plugs from random ebay sellers, new. all spark plugs have a certain limit for spark gap, which widens during use until it is too wide. Just get the proper type from ebay or 1aauto or rockauto, whereever. on lexus it is best to go with denso. however, different brands can give you a hard time, like going with bosch.

there are specific gap settings, for different engines, its based on the ability of the coil(s) to supply enough current to jump the gap with a strong enough spark to promote good running characteristics. You used to have to set the gap before installing plugs in the 80's and 90's because the preset gap was .. well .. massive.

Spark plug gages have been around for as long as I can remember. Individual blades with varying thickness to precisely measure the gap.
I have always held NGK in high regards, especially their iridium line. You can pick up a spark plug gap tool at any car store or wallyworld. They run 50 cents to a couple dollars. It takes 2 seconds to gap your plug and it simple. Just google it or search you tube. Having just gotten my Es330, I haven't researched if it has Plug wires yet, but if it does, I would highly suggest changing out those also. You can have just as many problems from old wires as old plugs.
Since this is probably a once in a lifetime event, don't go cheap on them and get the proper ones!!
