Hey guys i'm looking to change my spark plugs. Which brand/type do you recommend for a possible performance increase? I had read that the torquemasters were good but I cant find them anywhere. Any suggestions?
Thanks

you can get the tq master from carson toyota. i have them, no complains. but honestly i think they are all probably about the same

 

Thanks for responding romini. I know this topic has been discussed and there was all this hype in the past about the torquemasters. Just checking to see if anything new came out.

 

Does anyone have any opinion about NGK's spark plugs? I was thinking about going with NGK plugs and a NGK wire set? GS3.

 

no problem, glad i could help

personally, instead of checking that extra 1 or 2 hourses from the plugs (if any), might as well focus on saving money for the tq converter

 

Romini,
I am thinking about doing the tc but am worried about the warranty. Does the tc put a lot of stress on the tranny? For now I just wanted to do a few things like srt intake, and plugs.

well, it does put quite a bit more stress on the tranny, so you MUST get tranny cooler at the same time. that's a must, otherwise you risk blowing your tranny over time. but with the cooler then you are pretty much safe

and umm.... what yr gs4 do you have? i thought most gs4 warranties are out already?

 

Romini,

I have a 1999. I purchased an extended care warranty from lexus up to 100,000 miles/2008. I have 70,XXX miles now so I wouldn't want to void the warranty on the tranny by installing a tc.

 

ah gotcha. well, it's your call. personally i don't really care much (i would love to put tc on my sc430 now), but that's just me

 

When I get my pi tc installed on my gs430, I'm going to replace all the tranny fluid with fresh type iv. Do you guys recommend adding lucas tranny additive at the same time - or should that stuff only be added when you have tranny problems?
