I need to buy spark plugs for my car, change the rear differential fluid, and replace the serpentine belt.

1. What are the oem plugs? I've seen Denso a few times searching.

2. I will be using amsoil 75w90 diff fluid. Synthetic is preferred correct?

3. Are friction modifiers recommended for non limited slip rear ends? I.e. factory gs400 rear diff.

Thanks

 

A fourth question I should add here**

My oem headlight housing is broken beyond repair. It's factory hid equipped. Is there any difference in housings between hid, and non hid gs's?

 

4. huge difference hid have different bowls

 

Answered my own spark plug question...

Oem is: Denso SK20R11

Good to know man! Thanks. Would you purchase an aftermarket on on ebay? I probably will. I've had good luck in there.

I am doing my spark plugs too. I'm buying from Sewell
Weird thing is I noticed 2 different models for 2000 gs300.

9091901196 PLUG, SPARK PK16TR11 for 6 @ $41.70
9008091180 PLUG, SPARK SK20R11 for 6 @ $45.18

Which to buy and why???
