I just bought a new Toyota coil for $58 shipped (including tax) from Serra Toyota. They are cheaper than Denso right now. I'm on a roll and had two fail in the last month, but at 340k miles, I can't hardly complain.

Do you have a promo code to get it that cheap? I'm showing $110.73 before shipping.

Make sure you add it to your cart and then look in the cart. Some of the discount magic happens there.
I recently bought my 06 LX470 and saw this thread and went to check on my plugs and have to replace anyways since im at a 115k miles. I thought they were all good until i got to cylinder 3 and pulled it the coil was super brown and the rubber at the bottom was so brittle i touched it and it crumpled. Then went to turn the plug and boom super easily comes out so definetly was very loose. I also noticed some of my coil packs even though the boot was fine and supple the coil pack had a crack in it, about 4 of them had that cracked issue and I ended up buying the denso ones from rockauto and just bought all 8 instead. I appreciate this post any later and I wouldve been the next case.

I was replacing spark plugs and noticed two on left bank were so loose that I was able to remove those with bare hands. Tomorrow I will be re torquing all the spark plugs, should I torque these to 18 ft-lb? Seems like thats general consensus here ?
- Toyota Factory Service Manual (FSM): 13 ft-lb (18 N·m)
- Common IH8MUD community practice: ~18 ft-lb
Also how much should i torque the coils?
One last thing, some of the coils are showing heat cracks, I have one spare brand new duralast coil, is it ok to use one duralast coil?
Agree - 18 ftlbs good - on a dry thread.
Not had any issue with the coil bolts backing off - so until tight.
Replaced my coils with Amazon Denso 673-1303. A lot of people doubt their 'authenticity' and it's probably reasonable, but I'm on a budget so took a chance - OK so far (5 years but low miles). If the coils are degraded I'd change 'em out for best ones I can afford/willing to spend. If you go with a cheaper option maybe hold a couple of spares in the truck ready for changeout for failure on the road/trail - the most basic ($10) ODB scanner tells you the problem cylinder. Good luck.

Just wanted to document another occurrence. 2006 LX470 with 115,000 miles. I purchased the truck with 65,000 miles and noticed an "exhaust leak" about 1,800 miles ago. Went to investigate the issue and while I was under the hood decided to do some routine maintenance. Pulled the plugs to check the vintage and condition and was sick when cylinder #7 coil came out with the spark plug. Threads totally trashed. Scoped the cylinder and thankfully no damage was apparent in the cylinder walls, piston or valves.
Purchased the kit from Time-Sert (4412E-111) and repaired the threads. Pic below of repair with Time-Sert before cleaning.

Surprising, no DTC P0307, in last 1,800 miles.
Be interesting to see borescope pictures of cylinder wall in #7 now, and again in 5K miles after Time-sert installed. Also compression test now and in 5K miles.
Yes, should have mentioned it did have a misfire code. Runs like a sewing machine again like nothing happened (for now) but agree that a compression test and cylinder wall inspection should be done. I'll do that when I do a timing belt replacement this fall and try and remember to report back.

Compression test now, before running more than to get to operating temp. Is much more meaningful.
Better would have been, pre time-sert.
