Use NGK Ruthenium HX plugs. There are no wires so no need to replace.

The OEM plug for a 2000 TL is the Laser Platinum, PN PZFR5F-11. However, that was before Iridium. Since Iridiums came out, most guys replace their old platinum's with those. It's not that the performance is necessarily any better, but they tend to last longer since Iridium is a harder alloy. Here are your options:



The new Ruthenium supposedly last even longer but I don't know if there's any evidence of that yet since there would be very few cars that have gone 100K+ miles since they came out. NGK states that Ruthenium also creates a more efficient burn but I'm not convinced of that either. According to their website, Ruthenium plugs were designed for newer engines. Not to say they wouldn't work just fine for older engines though. But personally, I still use the Iridium's. They've worked fine in the past are are much less expensive.

Price is not a factor when selecting Ruthenium plugs vs other plugs because Ruthenium plugs are more efficient and will make up for the price difference and then some with better MPG returns, better sparks, and better sparks for a longer time period.

Again, not convinced of any of that. More efficient/better spark/better mileage - all claims but no real data to back it up. NGK has some info on their website that claims they're better but naturally they're going to tell you that the most expensive plug is the best. Until I see some independent data, I'll stick with the Iridium. As long as the OP gets a plug that has the correct gap and heat range, they're likely going to work all the same. I doubt there's going to be any difference whatsoever, especially in a 20 year old engine.

OP,

You can decide the type of plugs to use based on someone else's experience or opinions? Most people would choose experience over opinions.

LoL, so no one here have actually used or using the Ruthenium plugs except me and yet you guys have already formed your opinions based on nothing? That is just so wrong on so many levels.
