Price of ignition coils?

I'm needing probably 3 or 4 ignition coils. I've found them on Toyota's parts online website. The generally have good pricing, but my complaint is their atrocious product descriptions and search engines.
https://parts.maderatoyota.com/
It appears my 2000 4.7L Tundra requires Part Number: 9091902230. About $100. That's reasonable for a set of 8. I would assume they are sold and replaced in sets, and around the internet it appears a set goes for about $100-150. Yet, these might be sold individually?

But when I walk thru adding to my cart for the job it adds 8, for over $800. For coil packs. This cannot be accurate?!?!

A set of spark plug wires is generally around $50. I cannot believe a single coil which is not complex is $100... ?! A set is crazy expensive.

 

you can buy Denso coils for half the price, they are the original makers of the coils 50$

side by side they are the same, just missing the Toyota stamp that looks shaves off.

buy them from Rockauto.com (clickable link)

Go here, read most if not all of it, then you should go to big gurl and order a set for cheaper per Heather’s reccos

I personally use the Spectrum ones put about 5k miles on them no problem over 2 week period. First 2.5k was going 70 mph on the I-80 back to Cali 18 hours >4 hour break > 18 hours. The other 2.5k was going 55 mph towing back east same deal just took longer. If they were gonna crap out they would had by then. So far about 8k miles and just did my oil change. I'm running AD Delco Double platinum spark plugs got about 10k miles on them so far, still in good shape. Cheap unknown ebay ignition coils stay away from unless you plan on carrying extras in the truck. Before I got the Spectrums the previous owner had an eBay set that was on there started to crap out one by one. Which were change out with ebay spares that came with the truck. Which all got swap out with the Spectrums.
Denso are $48 at Rockauto $20 for the Spectrums.

 

I've actually been hearing about counterfeit parts even on Amazon. Even counterfeit flashlights. I'd probably order these Denso coils from Rock Auto or another place at this point. Amazon has too many 3rd party sellers.

 

Looks like Rock Auto has these for cheaper than Amazon too. $47.99.

 

Has anyone here used the trq coils?

i still havent talked myself out of the msd’s yet either. Red means faster, right?

 

I’ve been running 1A auto coils for a year and a half now. No issues so far. Set of 8 for $150.

 

Same here. Sounds like when they get the 'same' (some legit and some counterfit) parts in from different sellers they all go into a bin and mix together. Then Amazon just picks out the quantity that is ordered and sends them your way so you really have no idea what you're getting.

 

That's good to hear but not now for me since I forked over the skrilla for OE cause I didn't want any issues.

 

Thanks @jerryallday for the very helpful post with a link.

$50 is more reasonable than $100 for sure. Looking at these, they are just a plastic and rubber boot with some very simple electronics. I'd have guessed they are $20 each. $50 is closer to reality. $100 is nutz.

 

Simple electronics? lol

That’s kind of like saying a cheap speaker coil is just as good as a more expensive better built one. The quality of the insulated coil and the ability to stand up to heat, vibration and voltage breakdown during its life makes a difference. So materials used and consistency in fabrication make a big difference.

I will agree $100 is overpriced and going with the $50 Denso equivalent is your best bet.

 

Original factory toyota coil


Denso without Toyota branding (looks shaved off)

 

Get the Denso, but only replace the failed ones.

Maybe buy one extra for spare. Coils are typically not replaced preventively as they tend to last a long time.

 

so, just to avoid what i see come in at work a fair bit. Aftermarket coils will work usually. BUT the way Toyota uses ignition sense, the aftermarket coils can kill the whole ignition system depending on how they fail. once IGF is lost your usually fine, but with aftermarkets they seem to ground or or do something weird and it kills the whole circuit until the bad coil is removed. MANY tow ins over the years due to aftermarket coils (on any 4 wire ignition coil setup Toyota).

spend the coin for denso off rockauto (Avoid ebay and Amazon) and replace the ones that need replacing. its not uncommon to see Toyota coils go well over 300k (hell my corolla was on its originals after 800k+

 

Hi how are your ignition coils standing up. I am considering that brand as well

 

Denso. Replace all then you’re good for another 15 years. I’ve played the chase the misfire game.

Mine have been puffed, cracked and burnt for over 100k but all still work. Last plug swap I put new NGK boots and seals on them. That was 2 years ago.

When one goes, they are all getting swapped with Denso from Rock Auto.

 

I'm fairly sure my 253k mile 01's have the original coils. When I changed the spark plugs out last year for the Denso's I noticed that a few of the coils had cracks in them. I really wanted to replace but also was hesitant that $800+ was the price of entry for OEM's. The $400 Denso sounds much more palatable.

Question though, is it really better to do them all at once, or could I just replace the ones that are cracked?

 

I second going to rockauto and buying Denso coils. OEM is Denso.

 

I 2nd the denso…I cheaped out and bought cheap ones…last about a year and 5000 easy miles.

 

There's a boot and seal replacement kit for OEM coils? Do tell more. I wasn't aware of it. A couple of mine are showing signs of heat/browning.

That said, I can't reiterate this point from above enough: DO NOT buy auto parts on scAmazon or fleaBay, and now even Wallyworld is a venue for bogus/counterfeit/shady parts from 3rd party sellers. Stick to trustworthy sources, local auto parts store (LAPS), RockAuto, Summit, whatever.

I understand the drive to save money, if you want to save money, just don't replace ALL of your coils. If you're throwing codes on a specific coil, swap it with the one next to it, clear the code, and see if the code follows the coil pack to its new home. If not, it's probably not the coil pack. If it is, just replace the one coil pack w/Denso branded. $350-700 saved instantly.

Aftermarket:

I got mine straight from NGK, boots and seals all for $33.

https://ngk.mypartfinder.com/

 

The NGK look nice, but with the perpetual 5% off coupon Tundras.com members get at RA I'd rather just pay the extra $10 for OEM/Denso.

 

I thought denso doesn’t make them. I know you can’t buy the boots from the dealer.

 

Denso direct: https://densoautoparts.com/find-my-part.aspx#ProductDetail

True, can't get it at the dealer, but apparently they make it.

I think Toyota sells as a single boot. The part number is possibly 9091911009, but that may be the Prius version. Not sure what the Tundra version is. Will edit this to update if I see it.

 

So is it basically worn electrodes cause high heat, which then gets absorbed thru the coils and makes the plastic then cracks?

 

Do the cracks actually cause arcing issues or does the appearance just scare people? I've got two new denso coils I'm keeping in the truck and I'll just wait till I have an issue to put them in. I don't recall if mine were cracked when I changed my plugs a while back. Didn't give it any thought back then.

 

Yep, moisture can get inside and cause a resistive path to ground leading to poorer sparking conditions. You want as much isolation as possible for a strong spark.

ive also read that, and maybe its too dry where im at to matter, but all 8 coils were cracked on the sequoia, and it never gave any troubles. Was gonna steal a good one to replace my cracked one in the tundra, but couldnt find one.
