@2001LC I bought them off amazon. At the time no local parts place had them in stock.
the user pics of the product packaging on the amazon ad say made in china now.I heard Denso had a plant in China. I have bought a lot of bootleg Denso stuff. But none said made in China, but was and was junk.
@AlpineAccess do you have a part number for those NGK boots?
@bamabrock that was my review on amazon!
Per Denso, it looks like they have manufacturing plants all over now: Global Network | About Us | DENSO Global Website
Interestingly, they have a factory in China listed as the ignition coil manufacturer WUXI DENSO AUTOMOTIVE PRODUCTS CO., LTD.
But it has been about 2 years since I rebooted and no issues so far.
Adding to the data...
MY: 2000
Miles: 239k
Coils: Original as far as I can tell. Toyota part numbers on them
Plugs: Denso Iridium SK2011. ~50k on them.
Symptoms: None really. "D" vibration. PM prior to Alaska trip this winter.
Replaced with Denso coils as seen earlier in the thread and Denso Iridium TT spark plugs.
All 8 of my coil packs were cracked. Spark plugs all looked the same - dark/burnt looking threads and point, smelled of gas, except one had a brown ring on the white shaft. All had dried out dielectric grease on the plugs/coil pack insides.
Brief test drive: "D" vibration seems to have disappeared. I guess it has more spunk... slightly quicker response. Will see about any MPG changes.

Does the car feel more responsive on take off or general like entering freeways or from lights etc.
I love threads like this, and I am reading my way though it (currently on page 8). I don't understand why I wouldn't just replace all eight coil packs at once with new Denso/ OEM ones?
It's my personal experience that if the local auto parts shop and/or dealership sells one coil for $100 or $150... then odds are I can buy all 8 new, OEM online for about less than the cost of just one locally...
If I can get 8 new Denso coil packs in New Toyota branded packaging for about $100 - $125 with free shipping, then it doesn't really make sense to me to buy them individually?
Toyota part number: 90919-02230
So I am 100% in the buy all 8 and replace them as a set.
My truck has about 260k miles on it, and I am ordering and replacing the coil packs now as preventive maintenance as I try to improve my MPGs.
Did I misunderstand your comment? Are you trying to say that you are able to source all eight (8) in a package for $100-125?
Yes, you can buy them for less that $125 individually through the dealership, but if you go through a few of the local parts dealers or a few that have been a huge help here on mud... (@cDan) or others... they can probably help get you better pricing.
I am a huge proponent of replace all at the same time, but $800 or more on factory replacements is a tough pill to swallow for some people.
Also, electrical components can be unpredictable. Some can last forever, while others could have shortened lifespan due to unknown reasons. Alot of guys use this as sound reasoning for replacing them as they go out.
I'm speaking to all of this from the fact that I just replaced one. I used a Denso unit to troubleshoot it and ordered a factory Toyota replacement to put in its place. I'll keep the Denso unit on hand to help troubleshoot any future misfire issues that come up.
That is correct. Online vendors often are 1/2 to 1/3 the price of local retailers. there are a dozen retailers on eBay selling a set of 8x Denso/ OEM Toyota coils for about $125.
