I think the plugs are very reliable and chance of failing is quite low so I will take the risk.

Worth the risk to me. It's not like you're buying off-brand sparks plugs, these should be OEM and backed by Amazon. I got mine off eBay but same concept, I've also bought over 50 plugs from online venders with no issues but 1 faulty plug which they replaced free of charge.

Okay...thanks for your help...will ask what the cost of replacing back 3 ignition coils would be...sounds like a good idea....Lexus dealer's [western suburbs of Chicago] hourly rate for service is currently $160/hr.

They are exactly the same plugs. You really should replace the back three ignition coils too in case they fail after spark plug change and you will be charged another 3 hours of labor to reopen the engine bay like me. =(

Should i buy the three[3]ignition coil-packs from Amazon [@$57 each] and then let the dealer install [not sure there would be an extra labor charge to change and install the back 3 coils while replacing all 6 spark plugs] OR just take the risk that the Lexus dealer techs would replace all of the spark plugs [total of 6] without needing to replace the 3 back ignition coil packs... i will be supplying the dealer with 6 OEM spark plugs [purchased from Amazon]so will be charged for their labor only.
Dealer quoted me a price of $140 each for the 3 back ignition coils pack installation...must include a labor charge.
Need some perspective here as i'm not a mechanical person [wish i was].
Appreciate everyone's guidance on this issue.

Buy the coils on Amazon or any trusted source for OEM parts. They should not charge you extra for something that is taken out anyways for the spark plug change you just need to have all the parts ready before they start. Personally I would just change the back three, the front three are easy to access and very easy to swap when those fail. Also KEEP your old coils! Since they haven't failed yet, it's nice to keep a few spares.

Also agree to keep the old ones. With 3 new ones in back, they'll put the whole engine back together. If for some reason one of the front one fails during the whole process, you have 3 more chances for them to get it running correctly before they charge you for a "Lexus Coilpack".....at that point, if you have a bad one you'll have to pay the extra because it's already in their shop.
Now logically, I really don't understand how a coil pack can go bad by simply changing the spark plugs.....but it did happen to me. First go around the engine was literally sputtering and misfiring terribly! I really couldn't even drive it in any way!!
Lexus probably won't warranty the work but I bought my plugs and coil packs off of Amazon with no issues. Just stick with the OEM ones.

Thanks so much ...your response makes sense...service guy at Lexus dealership keeps telling me that if i supply the parts there is no warranty....is there an estimated "life" for a coil pack....not a mechanical but if the coil is electrical i assume it's life can vary [like a light bulb]...does this sound logical?

This comment is intended to be helpful.
Is it possible for the OP to consider going to a good, reputable independent shop (or even a Toyota dealer rather than a Lexus one) for the same work at a lower cost and possibly without the need to supply parts and question warranty coverage?
Most shops (dealers and independents alike) don't like using supplied parts. They cut into income. So they will warranty the labor but not the supplied part. Makes sense, except that it is unlikely that defective labor will be the issue down the road.
To stay competitive, independents charge less overall than the dealers, and they can use OEM parts when doing so. Some will even use supplied parts, but some won't.

I had mine serviced at Toyota vs. Lexus for this very reason. Every time I called Lexus for a quote, it was always higher than Toyota for the same part or service. Only for warranty work did I go to Lexus.
