Guys, I have a quick question. Should I change my spark plugs now? I have a 2001 GS3 and it has 58K miles. Any suggestions?

Default tm plugs
I just installed my tm plugs in last night on my 98 gs3 and im happy, it took a while but it was well worth the time. I can feel the difference. It maybe because i reset my ecu for about 2hrs and cleaned the throttle body while it was apart.

Great write up brother. The first time I replaced my spark plugs was about 2 years go and I took everything off I mean everything and even after I did I only counted 3 spark plugs and wasn't aware that the other 3 were underneath all the caps and wires, so it took my like 4-5 hours. I just changed mines today and It took me about an hour and 15 mins or so. Not bad.

Exactly what do you mean; isn't your setup the same as in the pics just with the engine cover? You have to remove the 'coil packs' to get to the spark plugs. Just get you spark plug socket down in the opening and rachet away.

Man, I hate replacing the plugs. It's such a bee-otch lol. I just did mine a few days ago and it was pretty tiring. It's really not hard, but just takes a lot of time and patitence. The worst part of this is that the plugs I'm using now only last 10K miles between changes! Oh well, you gotta compromise when you go boost

Default Which plugs???
I just called a local Lexus shop in Houston and were given info that the stock spark plugs for a 1998 GS 300 are dual electrode platinum plugs. Denso PK16TR11. So can I change to iridium spark plugs? If so, what are the part number for those iridium plugs? Thanks.

What are resistor clips? Do you have a picture? And how much are they to replace?
