What should the gap be set to for a Roush supercharged 4.6L? I left it at factory setting but seems a little sluggish at 3000 rpm.

  • Depending on the modifications on your vehicle the gap will ultimately change. I would highly recommend speaking to your tuner and how the vehicle was tuned for the proper gap for the spark plugs.

    Brisk spark plug and Coil on plug install

    It took me less than an hour to install the plugs and coils. I had no problems. The car runs smoother and I noticed an improvement in performance. The car seems more eager to go than it did before. Cool!
