stroking Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) i had some plug trouble today and i found that the b8 plugs are not very good,i fouled alot of them while breaking in a motor. so i tried some b9 and it seems to be working good. i have to different kind of b9,s but i dont know the difference other than the GV at the end now the question,whats the difference in these plugs.........the blue label KGK plugs seem to also last alot longer. WHATS THE DIFFERENCE IN B9E AND B9EGV Edited May 25, 2010 by stroking Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted May 25, 2010 Report Share Posted May 25, 2010 generally plug fouling is caused by a rich condition. im not sure ive ever fouled a plug. ive run a lot of different NGK plugs over the years too. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted May 25, 2010 Report Share Posted May 25, 2010 Go to www.sparkplugs.com do a seach for the plugs in question. It will tell you exactly what the differences are. By the way what your saying doesn't make sence. You fouled b8es so you swithced to 9's. 9's are a colder plug so fouling should be worse with them. You don't really need to change heat ranges. Your probably need to mess with the cars to get them dialed in. Quote Link to comment Share on other sites More sharing options...

AKheathen Posted May 25, 2010 Report Share Posted May 25, 2010 i run denso irriduims, much better design than the ngk. you should be running br8 no problem if it's getting the right oil/fuel, and has good spark. check you pickup gap on the flywheel, try new plug caps, and make sure the oil is not separating in the fuel. i ran into that problem on my sno-go years back and switched from a 9 to a 10 and it stopped glazing them, but the real problem was too much oil deposits and dirty fuel making it glaze. you can torch the fouled plugs glowing red with a propane torch and they will work again Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted May 25, 2010 Report Share Posted May 25, 2010 anyone else run the ngk iridium br9eix? I have ran the BR8IEX's same heat range as the stock plugs. I have seen the denso iridums they are a better design. They have a finer wire center electrode. I believe they are IW24. Another plug that I run is a BPR8ES same plug as stock only the tip is a projected tip. It hanges down in the combustion chamber. Then you side gap them.

AKheathen Posted May 25, 2010 Report Share Posted May 25, 2010 iw24 is the 9's...iw27 is the 8 series Quote Link to comment Share on other sites More sharing options...

someone82 Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) Another plug that I run is a BPR8ES same plug as stock only the tip is a projected tip. It hanges down in the combustion chamber. Then you side gap them. When you side gap them, do you run the same gap as a standard plug? Also do you notice any difference in overall performance? I've ran side gap plugs in my rotory motors and noticed a difference, but that's it. Edited May 25, 2010 by someone82 Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted May 25, 2010 Report Share Posted May 25, 2010 I cant say that I notice a difference. I just do it for the principle and it only takes 2 minutes to do. Getting the spark exposed to the air fuel charge is much better than shrouding it with the ground strap. Quote Link to comment Share on other sites More sharing options...
