When I changed mine; I removed the electrical connection to the coil pack by pushing the tab on the connector in and then using a long screwdriver I eased the connection apart. Once disconnected just pulled the coil pack out and replaced the plug. It was the toughest one I ran into too.
autozone has iridiums for 13.00 and double platinums for 8.50 and my old 93 V6 works just fine with the Double Platinum Densos, compared to the Bosch Platinum 4's i had in it!! i know i listened to a friend and did that huge brain fart!! Bosch are for German cars but specd for japanese cars but belive me i noticed a group more pep when i put the densos in!! and they are good for 60K which to me is about the time change interval i am happy with and i have no issue with room!!
