I want to replace the spark plugs on my 06 EX-L and want to know if there's anything better than OEM. I remember when I changed the plugs on my ITR to Denso Iridiums there was a noticeable improvement in performance and fuel economy. I really liked the Densos. I also read about Pulstar BE-1 which are completely new to me. Should I go with Denso's for the Ody ??
