I'm going to buy a set of coil packs from ebay. Is there any brands I should stay away from or any suggestions for brands to buy?

 

Most swear by the ones from Global. For a couple of extra bucks, get a 10 pack. Spares are always nice.

 

Uneek or Global are the two preferred ebay vendors.

 

I couldn't find any uneek on ebay but I found an 8 pack of global for $84.95 shipped. Lets hope they end up working out.

 

brochf,
I recently purchased 8 coils for $115 (shipping included) and installed them in my truck. I have no problems with them. Took me about 1 1/2 hours due to the driver side coils on the rear due to the fuel rail, which I loosened and was able to access. Here are the part numbers of the old and new parts.
