Hyundai ignition coil packs

I am fixing a neighbors car and I believe she needs a coil pack. Local autoparts stores have them for about $105.00 each, I am looking on e ebay and see them for $55.00 for a set of 4?? Is the quality that drasticaly different?

I’d recommend checking out the prices on rockauto.com . They sell quality parts at a price cheaper than places like Autozone.

They looked pretty good, I went ahead and ordered one.

Jeez, yeah, that is ludicrously cheap. You can’t even buy a generic points-type coil for $14 these days. I’d be half-tempted to buy them just to see how long they actually last.
