I have a GS 300, 2002 and am thinking about upgrading the spark plugs. I have the TRD air filter which seems to have helped, but I would love to tweak it a little more. Any ideas of the best spark plugs on the market? Are there other minor modifications which would help too? Would love any input.

Do a search for torque master and you will soon find that we highly recommend them for a number of reasons.

I've heard TM plugs provide a nice performance increase and also last very long. I think read somewhere that they last as long as the OEM ones or even longer

I would have to say Toyota platinums, lasted 106k miles, changed them, could barely tell the difference. With a 120k service interval, it was an easy choice.

by toyota you mean ngk or nd platnums?

alot of people on here have there own preference . . . most will say torque master is the best, i have had oem denso plugs in my car and i changed to torque masters which were really awesome plugs then with all the hype about these plugs i wanted to change to NGK IRIDIUM plugs and those to me were no different then the torque masters plus my uncle works at napa so the ngk iridiums didnt cost so much as the torque masters would , dont take it to a any shop if u dont DIY because they might throw some crappy autolites in there or somthing

my tech recommends NGK V-powers... he also said that the torque masters and the pulstar plugs can harm your coil packs or wires... oh btw my tech is an ex Lexus Master Tech... who opened a performance shop... you might want to try going a degree or two colder..

now that i think about it.. I think we may have been speaking about spark plugs for my Supra.. which is a single turbo... I am sure that would make a difference...

Most people who run F/I setup go with copper plugs simply because they tend to replace them more often, plus it's cheaper. The TM plugs for our cars are only one of a kind as in I don't think there are more than one heat range available, making it less ideal for boosted application.

I ran OEM denso, TM, and NGK iridiums. All 3 plugs did their job, and TM gave me a small gain on the top end. When I slapped on a set of brand new Denso plugs, boy did my car feel slower. It felt better with the NGKs.

weird. gapped the same? I guess I'll do NGK Iriduims when I do mine. I'm only at 44k miles so I probably wouldn't notice a difference yet.

Anyone know the pn for NGK Iriduims for a GS430?

i put the ngk iridiums in my 01 gs430 and did notice a little over the stock denso's

chuckb

All iridiums are pre-gapped. Can't really gap them, otherwise the iridium tip will break

would the ngk last as long as the oem denso?
