2008年8月4日 · The BR9ES; the spark itself resembles an S. The br9eya is in my oponion a better plug, twice as much spark as far as im conserned. you can run br9eya's in a sled that requires br9es, if the sled requires a br9es and you run a eya, it wont run for shit...

2005年2月11日 · The EYA plug is referred to as an “anti-fouling” spark plug based on the design of the spark plug. BR9EYA is interchangeable with part number BR9ES you will not damage your engine. If you have further question please feel free to contact me again. Thank you for your interest in NGK Spark Plugs Canada Ltd. Jackie H. Customer Service ...

2005年12月21日 · Standard NGK BR9ES Copper Core for about 8 bucks for 2 NGK IRIDIUM IX BR9EIX for 12 bucks each Both plugs are the same "value" one is just more fancy then the other. What is the difference and why would I want to spend more for the better plugs? What gains if any would a motor see. Thanks,

2009年2月3日 · my polaris uses BR9ES, which i can get at polaris dealer 1.5hrs away.BR9EYA is the same but has a v in the electrode.and are stocked at the cat dealer 15 min away.i was told by both dealers it was ok to use.

2008年1月3日 · with NGK the lower the number the "hotter" the plug is. i believe "hotter" reffers to the size/strength/intensity of the spark itself. as for ev, es, e.. you can probably find out what the differance is on NGK's site, or somewhere on the net. the codes are like a vehicles VIN number in the way that each digit/letter represents something.

2009年11月4日 · This plug has a conical shape base which can allow for a shorter center electrode and a shorter ground electrode in comparison to the old standard BR9ES. The benefits of this are a reduction in pre-ignition and detonation by dissipating heat more efficiently via the electrode and conical shape base, along with a reduced chance of vibration ...

2009年10月12日 · The "P" does stand for projected tip. The electrode does stick out a little farther. You cannot swap the BR9ES for a BPR9ES (yes the will thread into the same hole). The electrode of the BR9ES will not reach far enough down into the head, thus not giving you a very strong spark for ignition.

2005年12月9日 · They came up with a variable heat range plug (or something like that). The NGK will work in a pinch for a spare, but I would go with the champions. They were specificly designed for that engine. You can't beat that. As far as BPR9ES verses BR9ES the only difference is the BPR9ESis a platinum plug thus the "P". :m2c:

2004年1月21日 · I realize this is a pain in the ass because i think it is as well. But here goes, I have been putting in br9es in my 600 SDI because this is the only time I have experienced plug fouling. I put the br9es gapped at .018 in and start it up. Once the motor is good and warmed up, I switch back to the br9ecs and away I go.

2006年1月11日 · the ES at the end is a standard thread reach center electrode the EYA V-grooved electrode A- special design - the elctrode is longer on some engine it may hit the top of the piston. an on the Y the insulator 2.5mm at may be a little hot thow the heat rating the same EYA are for Cat.
