Can anyone tell me which covers to remove to get to the spark plugs ?
I hate to start riping them all out, just to find I only had to take 1 out .
Also Bosch Platnium 4 ? or NGK ?

 

depends on what gen ls you have there buddy. As for mine , they only allow iridium spark plugs, in which only a dealer or qualified mechanic can get to...If you have a 1st generation, I'd suggest you consult your car manual to see if the bosch platinum plugs will do it for you.

 

I have a first gen LS.

This is what the manual says:

Spark Plug-Make Nippondenso PK20R11
NGK BKR6EP11

-Gap 0.043in (1.1mm)

 

Thanks for the info everyone.
