Best Spark Plugs?

I was wondering what the best spark plugs were for the 2000 GS400?

Bosch? Denso? Torque Master? any other brands..?

I want better MPG, and hopefully some more HP and TQ gains as well... all for a fair price.. any ideas?

I wouldn't let Bosch touch my car, simply because i've ran them in the past and they are mediocre at best, at least the so called +4 stuff.

NGK and Denso gets my vote, iridiums of course. They are well known companies, and are known for their OEM replacements.

I installed the TM plugs this afternoon. Seat of the pant tells me my car feels quicker (more power). Black mark on road will indicate that

. It's too soon for me to tell about the reliability, but out of all cases, i've only heard one or two bad cases of TM plugs in a lexus.

I've heard good things about TM plugs. I'll need plugs soon and will most likely get TM and hope to see a difference in performance.

NGK plugs are good.

I put TM's in my 98 gs300 with around 40k miles just since they had been in there so long. When I was in there I also cleaned the Throttle Body and butterfly, definitely worth it to get those plugs, they give you a few tq/hp
