Unfortunately, because of our plug design, we're limited on our selection of "cheap, disposable" plugs. And upgraded ignition components generally are neither required on our cars in high performance applications, nor are they bad for spark plugs. The problem with going through more plugs is because of the extra compression/spark knock/mild detonation associated with power adders (especially when they're new and need a little tuning tweak), which busts up the porcelain. I will never buy another Autolite plug as long as I live. I've had nothing but great luck running the Brisk plugs, so that's why I recommend them, and I've gone through over $1000 worth of "Brand X" plugs before I found the Brisks. Hope that answers your question.
