Default DEAL ALERT! D510c LS3 Coilpacks for FM Big Spark Kit

So I was looking at new spark setups and decided to get the FM hardware kit and take a gamble on the coilpacks. I know the ACDelco ones from vendors online are around $60 a piece, even more at FM. I took a gamble on these $20 units from Amazon, just came in today, and I am happy to say, they are 100% legit ACDelco units and look brand new. Snag up this deal if you're looking to up your spark game!

Good luck with those, the Chinese make them look identical they just don't work identical.

Then how can anyone with ACDelco parts be sure if they're real? Price is not an assurance of quality or authenticity. My friend back in the day was heavy into selling knockoff designer stuff at flea markets etc. we went to the Macy's in Manhattan NYC during a trip and saw a rack full of fake Lacoste polos for full price. I'll post some photos of these when I get home. I've seen knockoff coils but they aren't branded ACDelco. I was expecting one of two things.

1. ACDelco box with a generic China coil inside
2. Something rebuilt or with scraped off numbers or brand.

Pleasantly surprised.

And I'm telling you, people have had problems with cheap "OEM"coils. So if you find yourself blowing spark out when you shouldn't it's because of cheap coils, don't be surprised.

Rails of 4 stock coils are cheap on e-bay, I know mine are oem because I pulled them off a stock motor for cheap.

Here's 8 for $115 with good OEM pigtails (another issue) sell 4 and you are cheaper than what you've got now...

I was under the impression that ACDelco made parts for GM. See their name all over fluid bottles and other misc parts.

They do, but the stuff you are buying from Amazon for $19 isnt the same stuff. I wouldn't install those on my car if they were free.

In the last 5 years, ive gone through more ACdelco parts than I care to recall. Maybe 10 years ago they were better, but they have succumb to the "chinese supplier, make it cheaper than everyone else to stay competitive" game. It is quite agravating as I was a loyal ACdelco fanboy who went through a lot of parts before I realized they sold out, and it cost me a lot of money and time. They will never get a dime from me again, keep your cheap **** coils.

I think OEM coils have no mention of ACdelco on them, my truck LS2 coils don't at least.

More like this.

after being cheap and going with china coils, and realizing my mistake, I'd be willing to pay for used OEM any day over new aftermarket coils. I've gone through multiple sets of coils on two different cars trying to piece together a full set that didn't crap out under high load.

Just not worth the time, and you really don't save much after having to buy multiple sets to test

Thanks for the link. The seller also has sets of non-truck-LS2 (D514A) coils with harnesses for the same price. And I can take a hint from the chorus of "used factory coils be better than new knockoffs".

I ordered the 8 in the link and will return my ACDelcos. I'll probably keep the other 4 coils as spares, they are all used after all, and it couldn't hurt to have a few extras.

Thanks to everyone here as usual for keeping my build solid, I apreciate all you guys!
