    Have the same bike and Chaparral Motorsports sold me an NGK Laser Iridium(# on box is IFR8H11,with the #5068 beneath that),seems fine.

    Welcome to the site !! \:D/

    The IFR8H11 is the best because of the slim electrode , it gives a better concentrated spark that reduces detonation , i would personally stick with it , i have used E3 in cars/trucks , but i would not consider it a "performance" plug for a CRF450 engines demands , completely different animal than a car engine
