Thread: Projected or Non-Projected Spark Plugs For ProCharger?

  1. #1

    Default Projected or Non-Projected Spark Plugs For ProCharger?

    Just curious as to spark plug selection. Told to run a resistor style plug. Old plugs were R5671A-9. I want to go to a hotter plug due to carbon fouling. Plugs I found in a 7 heat range from NGK are BCPR7E. Question is what is the difference or benefits of running a projected or non projected plug? And will the BCPR7E plug be a plug that will work being it's a standard plug not a V-Power style? Or does that really even matter?

    You could ask ProCharger what they recommend.

    I did also send them the same question. I was just looking for feedback from other possible ProCharger users in the meantime.
