Hi. I saw a good write up with pics on installing spark plugs by Stats007 but could not locate it exactly.

Shouldnt be too difficult but I would like to locate the write up before starting. If anyone or stats can locate the thread I'd appreciate it.

Thanks in advance from UK.

I've never seen pix, but there are a few threads describing the process: remove plastic engine bay covers, remove red spark plug wire covers, remove each coil and plug.

spark plug

Thanks Deane. It was a very comprehensive write up with pics.

Also wondering if there is any need to use copper grease on the plugs.

Just Completed

Just completed this install - There is a definite improvement - quicker crank, smoother and a slight change to the engine that I can't quite put a finger on yet but positive. When you put the NGK and the Denso Iridium side by side you can see the difference Denso is talking about with "u-groove" technology and ".4 mm center electrode" which is vastly smaller than the NGK.

The only problem is that I don't know how old the ones I took out were so I don't know if the improvement is a result of new vs old or NGK vs Denso - probably a bit of both.

The link that gave the pics was excellent and I downloaded it and made a powerpoint out of it and printed - fun to do but not really needed. Took the opportunity to powerwash the engine and bay with the cowls off.

Note: I found by accident that at least 5 of my cam cover bolts were loose - something to check for. I have left the cowl covers off for now and will spend a few hours next weekend tightening and detailing before I put the cowls back.

They're a good install. We now carry the Denso's in stock after seeing the difference first hand.
