http://www.harley-performance.com/harley-exhaust.html Is a good web site for Harley performance improvement recommendations. One of the spark plugs they recommend for the 110 Screaming Eagle engine is the Autolite XS4164 Iridium. I just ordered 2 of these spark plugs off of Ebay for $4.10 each with free 3 day shipping. Then go to the Autolite web site for special offers ( http://www.autolite.com/special-offers.aspx ), download the rebate information at the bottom of the page and get $2.00 rebate back per spark plug. So I spent $8.20 on the spark plugs plus I'll get a $4.00 rebate. Ok, they're not free but I end up paying $4.20 for a set of excellent spark plugs. I have had these same plugs in my Fatboy for the past 4 years, put 15,000 miles on them and I'll tell you they are excellent plugs. I have always gotten quick starts, great gas mileage and no problems. Here is the link to the Autolite web site recommending the XS4164 spark plugs for the 1803CC engine.
