Spark plugs and wires

Thanks for the info.
PK20 (PK20TR11) are the ones to use i guess.
Guess i will use them.

If you want to get true OEM replacements, thier actually NGK platinum plugs on Solara Gen1/1.5.

I found that Iridium does last longer than Platinum (110k vs 60k), and performs better with a higher melting point (1200F higher).

I'd go Iridium. Considering they use Iridiums on the Lexus ES, which shares the same mechanics as the Solara, I would not expect any problems. I dont think NGK vs Denso matters, but dont get Bosch.

I really dont think the extra 40k miles you may get with iridium is worth paying the extra 4-5 dollars per plug. I assume you are at 60k on the odo right now. Think about it, are you gonna drive your car for another 100,000 miles? If so, it may be a good investment.

There is no such thing as a high performance spark plug. The only performance gain you will ever see with a plug is when you replace worn, old or fouled plugs with a shiny new plug. Whatever you get, stick to denso/ngk plugs and stay away from bosch, champion, etc.

Do not gap multi ground plugs. They should come pre-gapped.
