2006 RR HSE 160k miles

I have two ignition coils that are bad so I'm going to replace all 8 since the RR has 160k on it. My question is how much, if any, difference is there in coils. I see some cost 90.00 each but then I also find some that are 150ish for a pack of 8.

You get what you pay for. eBay coils are going to be exactly that, eBay coils. I would get a set from a reputable source, you don't want to cheap out and cause some damage because a cheapo knock-off coil melted your wiring harness or fried the DME.
