Here's all 6
Take a look at the picture and make sure you notice the circled letters on there b/c you'll have to plug it back in the right places. Sorry I couldn't get the top letter but once you get the "C" and "G" in place then the top is given. =) Also there'll be some dust, dirt, sand...in the spots where the plugs are at so what I use is a keyboard cleaner duster air spray to spray out as much as I could before I take out the old plugs. You don't want any of that stuff falling in. =| While you have the intake and throttle body off and everything, might as well give it a spray of throttle body cleaner to cleanse it.
Good luck and have fun getting elbow grease!

haha reviving this thread...anyways questions,
1. what does he mean by 'you need to twist the throttle cable cam back to release the cable.'??
2. what is that gold valve used for?
3. are the actual spark plugs under those wires that he's pointing to in post #10?
4. what is the "c" and "g". do i need to remove those to get the plugs out?
5. for the clips on c and g is there a special way to take it out without snapping them lol
lol i'm just used to workin on my integra...easy as cake compared to this

1) the throttle cable sits in this groove on a circular tensioned rotating apparatus that converts the pulling of the cable to a rotating of the throttle plate. u have to open turn this to open the throttle plate from inside the tbody. when u do that, u should have enough slack on the throttle cable to release its end pin from the apparatus.
2) gold valve? u mean the throttle plate inside the tbody (throttle body)? its to limit/restrict or to allow air flow in.
3) under each numbered point, when u pull up on the spark plug wires, u will see the spark plug. u need a 5/8in spark plug socket to unscrew the spark plugs.
4) those clips become brital from heat and ware. the plastic may crumble. just be careful. i ended up replacing my plug wires with ngk plug wires.
5) answered in number 4.
good luck.

I know I know back from the dead, but I was wanting to hear from the peeps who put in these t.m. plugs and to see if they are still running strong. They sound great but to be honest I am not "looking" for more power, mainly reliability and better gas mileage is my main concern. Or should I just get the Denso Irridium plugs. And not really worry about it. Veterans please reply. thanks as usual

Yep yep! It's all the same for the 2nd generation GS 300. For an extra step, before you take out the spark plugs, use an air duster can to spray out the dirt, sand, debris, etc. out of the area. There's plenty in there. Good luck and have fun.
