befuddled on removing spark plugs
This is not as simple a question as it appears and I'm hoping someone can shed some light on it. I'm a rather accomplished mechanic and started to change my plugs about a month ago and realized I couldn't get the coil packs out due to interference with the shock towers and other pieces of equipment under the hood. I have Googled and looked around to see if there was a "trick" to removing the coil packs but I haven't found a single reference to it. Do the coil packs disassemble some how? Otherwise, it looks like you'd have to literally lift the engine a bit to remove the packs where it's so tight. That doesn't sound like Lexus to me. Any advice would be sincerely appreciated.

Last month, had the spark plugs changed for one of my 600HLs, at 60,000 miles. I paid for the 60,000 mile service - $900 I think.. I am not sure.. When I asked about the breakdown, I think they said the spark plug change was around $350 or so (not sure of the number..). I do remember thinking, that it was not cheap to change sparkplugs.. but I was fine with it - typically, both my cars have been troublefree.. Well... except that for all three of my LS cars, the mark levinson amp blew.. and they replaced under warranty.

I used a pry bar to slightly move the engine to one side while removing each coil pack.
Hmmmm, I didn't see that tip in the service manual!

I understand that the 2008 and newer have a spark plug change interval of 60K miles - same engine and plugs as my 2007 -what gives.

I forget his name but one of our members is a service tech and he explained the reason. It has to do with Lexus going from only direct fuel injection to going to a dual port system. This fine tuned fuel delivery, but did shorten spark plug life.

How did the plugs look? I have a 2007 and that year has a 120K spark plug change interval. I'm at 83K miles and was hoping to go another 40K before dusting off the crowbar.
