Has anybody tried these 'Brisk Performance Spark Plugs'? They are a replacement for the H-D 4R5 plugs. Amazon is selling them for $17.98 plus shipping.

Resistor large gap plugs in that heat range would not be a good match for a Panhead.

I did some research on these BRISK-PLUGS!------Theres no problem using them with Iron cylds. & Alum.-heads!--They come in a 3-4 heat range.Also they had all the crossover numbers for 1948 to present HDs!.For Pan & Shovelhead you can get the 2-TYPES!-The Expencive IRIDIUM ones & the other ones which are gapless!.I didnt bother to write the numbers as in the article they Referenced to Autozone & Napa,& To cross-reference from champion, NGK, BOSCH,& AC.---I didnt crush one up yet!--Ill wait until some twinkee comes in for a tune-up & crush-up the old BRISK-E3 plug.I would imagine there robust//BUT just because thier $16 a piece dont mean anything!--Your paying for the Platinum & space-rock/(IRIDIUM).---Respectfully----Richie
