Meet Roger Wiliams, a Professional Racing Engine Builder and the owner of Williams Precision Engines. This video explains how we came to know Roger and more about his background, so check it out!

Every month, Roger will make a video answering some of your car, truck, engine, and aftermarket parts questions! In his own words, "I'll be blunt, and tell it as it is...If I don't know the answer, I'll figure it out and tell you what I found."

Leave your question in a comment below (or tag it #askroger #e3sparkplugs on Facebook, Twitter or Instagram) to be answered in his first video at the beginning of August! If Roger picks your question to answer on video, you'll WIN a set of E3 Spark Plugs up to a V8!
