Spark Plug - Harley Davidson 4R -1971 thru 85 Sportster

 This is a rare and hard to find New, Old Stock , Harley Davidson spark plug.  These plugs replace the original equipment in 191 thru 85 Harley Davidson Iron Head XL Sportster. These plugs were destined for the production line as seen by the factory packaging.  I’ve been buying and selling vintage ignition parts for over 40 years, and have only a limited number of these sets remaining. Domestic Buyers to pay $ 5.50 shipping.  Payment must be made by check or Paypal within 10 days of auction close.
