From: FLYaDIVE What is the difference between these two plugs? Why is there such a big difference that mixing of the plugs should be avoided? "The new 914 spark plug DPR9EA-9 has a Rotax part no. of: 897259 914 Spark plug X27EPR-U9 Rotax part no. 897257 is still valid, but any mixing of spark plugs part no. 897259 and 897257 should be avoided."

From: Richard Girard The DPR is an NGK plug, the X27 is a Denso. I found one site that showed the X27 as a heat range hotter than the DPR9, but the Denso site showed them as equivalent. I can't find anything else.
