quad4me Posted May 25, 2005 Report Share Posted May 25, 2005 (edited) Just put in the NGK BR8EIX Iridium plugs.....seem a hell of a lot bettert han my old standard BR8ES's. Will write a bit more after a good hard ride this weekend....weather permitting. Like $17 and change at Advance Discount Auto. Cheaper than online after delivery and such. Try em out....

jeepman380 Posted May 26, 2005 Report Share Posted May 26, 2005 I've been using these for awhile now and they are really good plugs. In fact i've had the same set of plugs in my motor since last May and they haven't fouled or anything. Still runs great like they were brand new.

sredish Posted May 26, 2005 Report Share Posted May 26, 2005 They're great plugs and harder to foul. They burn much hotter than the stockers and can help add that "edge" to your machine. One of the things I don't like about them is they seem harder to read than the stock plugs. I went through a difficult jetting period in my banshee after I ported it and when I went back to the stock plugs, it made it a lot easier, and I've never gone back to them.

SANDSTAR Posted May 29, 2005 Report Share Posted May 29, 2005 (edited) I just can't justify the price. Where exactly do you see the improvement/ worth of these plugs? For 18 bucks I can get 4 br9es. Seems like alot for plugs in a machine that requires several chops a year if you change elevation/riding areas like I do. I don't like the idea of chopping a cheaper plug, and then running a diff. plug after adjustments have been made. Why pay more to get a hotter plug? You can adjust the heat range of the ngk plugs by going with a 7 or a 9 instead of the regular 8. Are there hp gains? Tq gains? If you are fouling regular plugs, you have jetting issues. I do not understand how these plugs fix a fouling situation. I wouldn't want a bandaid fix to a rich/lean condition.

locogato11283 Posted May 29, 2005 Report Share Posted May 29, 2005 i just started running these plugs only because i cant get the br8ev's here anymore. they told me at several places now that the iridium plug is the replacement?? oh well. i got mine from a buddy at a yamaha dealership so i didnt have to pay anything for them. i too have a hard time justifying spendin more than about 4 bucks for a spark plug...

macgillivary Posted June 3, 2005 Report Share Posted June 3, 2005 i run the stock 8's but have seen the br7's and 9's I didnt wanna mess with them but whats the difference between the 3 of them the temperature ya but which one is hottest and coldest? Thanks Quote Link to comment Share on other sites More sharing options...

I wouldn't want a bandaid fix to a rich/lean condition. 375138[/snapback] not that I am fouling...but they were there and thought I would try them out anyway. I had the cash...so. BUT, yes I can feel a little more "peppy-ness" out of the bike after I swapped them out. I am not a dyno or anything...but shit....for the $ I would convince myself of gains no matter what. We shall see how they run in the trails soon...the rain sucks here this week. Once its not like 2000% humidity I will take her out and run the piss outta the thing.

sredish Posted June 3, 2005 Report Share Posted June 3, 2005 The idea is kind of this, with the hotter plug, less fouling, it may be possible to bump your main up another size and get more fuel to burn in there with less chance to foul, and that would be where the power gain would be. I've never used them to "fix" a fouling issue and they shouldn't be used as such. They are simply a plug with a hotter spark and can burn the fuel more efficiently. For 99% of the peeps, there will be 0 difference. I ran them for about 8 months, bumped my main up some and they weren't too bad, but I'm now back to the BR8ES, plain and cheap. Also, I WOULD NOT switch from BR8's to BR9's or BR7's without the advice of an experienced engine builder. If you have a BOATLOAD of mods or something to need the different heat range, and are advised accordingly maybe, but don't just buy a different heat range to try out, especially if you only have pipes, and the little podunk mods the majority of us do. Stay in the "8" heat range. If you read the plug and are getting a very obvious problem with the heat range of the plug, I understand, but half the peeps don't even know how to read the plug for lean/rich let alone heat range.

SANDSTAR Posted June 3, 2005 Report Share Posted June 3, 2005 Spark plugs do not create heat. What the heat rating on a spark plug actually is is a heat dissapation rating. The "hotter" the plug,( B7es) the less heat it will dissapate. These plugs have more surface area (insulator nose is longer) in contact with combustion gasses, therefore remains "hotter". A B9es has less surface area exposed (insulator nose is shorter) therefore it will dissapate heat quicker into the cooling system. These plugs are used with High compression/high performance engines that see higher internal temps.(nitrous) But these plugs will foul easier due to the fact they don't burn off as much carbon as a "hotter plug. I run these plugs. This is why draggers are always changing plugs. Don't change from br8es unless you understand and have reason to do so. Hope this helps.

banshee x Posted June 4, 2005 Report Share Posted June 4, 2005 Anybody heard of Rocky Mountian Atv under 2 buck a plug. Buy ten at a time and it justifies shipping. Quote Link to comment Share on other sites More sharing options...
