2005年3月12日 · The CR9E is a colder sparking plug than the CR8E. Numbers going up generally mean colder plugs. If you ride "conservatively", it may be too cold for you, but if you "thrash" your bike near its rev limiter, it will work fine.

2010年9月14日 · So from what ive read the iriduim plugs do in fact last longer than a standard plug and can sometimes help an engine start easier and whatnot. Since the 9 is a colder plug than the 8, will it help lower the engine temps at all? Maybe 5* or something? Ive also heard that it can improve low end hit...

2004年11月8日 · The number in a NGK part number reffers to the Heat range of the plug. the hight the number the colder the plug so a CR9E is a colder plug than the CR8E both plugs should work, for alittle extra performance I would recomment a NGK CR8EIX

2017年4月8日 · CR8E cant be obtained locally and have to be ordered online = have to wait which I prefer not to. The bike runs unsmoothly, quite noticable when giving steady throttle at cruise speed, I can feel power surges and power losses, like hickups every few seconds.

2005年4月20日 · The only option listed was the iridium version of the CR8E. Link to comment Share on other sites.

2010年1月17日 · I put in a CR8E which is standard. CR7E is the Hot Type and CR9E is the Cold type. Here is some information regarding the differences: "A spark plug is said to be "hot" if it is a better heat insulator, keeping more heat in the tip of the spark plug.

Also, in case you didn't know, you can get equivalent plugs from different manufacturers. Just ask the guy at the counter to cross reference for you. They should be equivalent in temperature.

2013年8月7日 · The plug designator is the CR8E C= Thread size / Hex size 10mm / 5/8” (16.0mm) R= Resistor plug. 8= Heat Range. E= Thread reach 19.0mm (3/4”) Notice the Logo on top... NGK R and the stamped part number on the steel hex (yes this is a CR8EK,,, because that is what i use.. but same deal with the CR8E) Other side of same plug..

2008年2月8日 · Since we are on the topic of spark plugs. I looked on line at one of those micro-fische parts catalogs and it listed the stock plug for a 2003 KLX400SR as the CR8E, but then it said it had been superseded by the cr9e.
