pic request
ive been look through threads and cant find, please im trying to replace my spark plugs on my sc300 but can somebody give me a pic of what part to take off the intake and manifold so that i can get to the spark plugs thanks

I just replaced my wires a few weeks ago. I'll post some pics and links that I used when I get home. Just gotta turn some bolts, take your time, and be patient. It is a good time to replace the spark plug wires as well if they are old to save you the trouble down the road.

Yea man the wires on my car had "1992" before I changed them. Not sure if you have found this link, but it was very helpful when I did it: https://www.clublexus.com/forums/sho...d.php?t=103316
I ended up using the method that removed the throttle body because I could not find a way to reach this one bolt on the upper Y intake manifold.
Here are some directions from the manual. I used the directions on the thread mentioned above. The following directions are from the manual:
Spark Plug specs:
Electrode gap 0.043 in (1.1 mm)
Torque value 13 ft.lb (18 Nm)
1. Remove wire covers.
2. Remove throttle body. Refer to FUEL SUPPLY AND AIR INDUCTION .
Disconnect negative battery terminal.
Drain engine coolant into an approved container.
Disconnect cables from throttle body.
Disconnect PCV hose from valve cover.
Disconnect power steering air hose from timing cover.
Remove throttle body bracket.
Remove the following connectors and hoses:
Throttle position sensor
Sub-throttle postion sensor (if equipped)
Sub-throttle actuator (if equipped)
IAC valve
4 vacuum hoses
Remove throttle body mounting hardware.
Disconnect 2 water bypass hoses.
Remove throttle body and gasket.
Reverse procedure to install, using a new gasket and noting the following torque values:
Throttle body - 15 ft.lb (21 Nm)
Throttle body bracket - 15 ft.lb (21 Nm)

Drain engine coolant? I don't even disconnect both coolant lines. I disconnect the one underneath the throttle body, and unbolt the bracket holding the throttle cable to the y-plenum, and just move the throttle body off to the passenger side rear of the engine bay with the other coolant line still hooked up.
