I would strongly recommend using NGK PZFR5J-11 spark plugs. These NGK Laser Platinum plugs are the best option for your 2.5l. Not only are they pre-gapped and ready for installation, but they'll perform great and provide dependable service for several years.

Pros: best option, pre-gapped, great performance, dependable service

Vehicle: Volkswagen Golf

Part number: PZFR5J-11

I'm running a Blue coil (only because the blue is cool), a compufire, and bosch plugs and wires. The blue coil is juat something to look at. You really wont notice a difference.

Cons: no noticeable difference
