Hi, I intend to replace the spark plugs on my 2000 ES300. It seems that 3 of them are visible in front of the engine, but the other 3 are buried somewhere in the back. Any tips on easy access to them? Also, it seems that there are only 3 ingnition wires for this engine (V6 3.0). Are the oher 3 attached directly to an ignition coil? Thanks in advance. ---Lev
