Thanks for all the input guys.

I got 4 x PFR6B NGK plugs from supercheap for just over $19 each. I guess I will find out next week end how hard they are to change. I dont have a 3/8 drive socket set so we will see.

Watch this space.............

no hope with 1/2" drive, 10mm ratched spanner is great for undoing the coil packs too

Spark plug remover should be part of your toolkit in your boot...
It's the long hexagonal shape thing. you have to use the wheel nut wrench over the top.

There will be a rubber bit on the inside of the hex thing for the end that goes over the sparkplug.

Spark plug installation is the easy part. Pulling off all the junk around to get to them is the fun/ time consuming part.

Cheers,
Fred

Done the plugs on Tuesday with a 1/2" drive socket set and yes it was a bit fiddly but not really a problem at all. Coil packs came off with a 12mm ring spanner, no problems there either.

or pick them up from England of ebay for $50,
still come from ngk japan
only take just over a week
