COIL ON PLUG 99 p71

I need to replace my coil on plugs i dont have the funds to shell out 800 for all 8 0f them so any suggestions on best ones to get for low cost at autozone advance or anywhere else. Or just would like to here you guys 2 cents.
Thanks

Why replace all 8 of them? For now just replace the ones that are bad. Sometimes all you need are the boots that go on the coil. They are a lot cheaper. The boots just pull off and the new ones slide on. Look at the spring while the boots are off and see if any are burnt or rusted.

Do you know about these after market brands that are identical "OEM" to motorcraft if they are worth buying them.

I would NOT buy any aftermarket electrical parts.

I also would not buy "new" OE parts with plenty of perfectly good experienced parts just waiting for a good home.
