BobBrumby Posted May 21, 2005 Share Posted May 21, 2005 I got some NGK BP6Es spark plugs for my subaru brumby but they are gapped at 0.9mm or 0.035433". Arenot they meant to be 0.044" and will running these plugs do anything bad? Quote Link to comment Share on other sites More sharing options...

BobBrumby Posted May 21, 2005 Author Share Posted May 21, 2005 dam they are gapped right for my brothers suzuki swift, same plugs Quote Link to comment Share on other sites More sharing options...
BobBrumby Posted May 21, 2005 Author Share Posted May 21, 2005 My gregory's manual atucally calls for 0.7-0.9mm gaps which is quite a bit less than 0.044" or about 1.1mm. What will running these plugs do? Quote Link to comment Share on other sites More sharing options...

torxxx Posted May 21, 2005 Share Posted May 21, 2005 .045 and I'm stickin to it.... Wider the gap, longer the spark, the better the combustion Quote Link to comment Share on other sites More sharing options...
BobBrumby Posted May 21, 2005 Author Share Posted May 21, 2005 .045 and I'm stickin to it.... Wider the gap, longer the spark, the better the combustion Was this with the MSD Blaster Coil cause I just got the stock coil. Quote Link to comment Share on other sites More sharing options...

moshem74 Posted May 22, 2005 Share Posted May 22, 2005 .045 and I'm stickin to it.... Wider the gap, longer the spark, the better the combustion you are wrong my friend....the smaller the gap is - its better: 0.7mm is the best for your car. you can open google ans search for spark plugs gap and read some articals about it....

Phizinza Posted May 23, 2005 Share Posted May 23, 2005 I don't know how you figure it to be bad. I looked it up in google, only bad thing i read about it is if the gap is too big and the spark doesn't make it across. If you are running stock every thing, then yes keep the plugs gap at what the manual says. I bought myself a Mallory Promaster coil. I also got some bigger leads. I now run my plugs around 1.1 to 1.3, forgot exactly what it is now. bigger spark from coil can be used to your advantage. More spark = more efficient burn, and also more power as it burns the fuel better and quick.. Anyway, just my 2cents. Quote Link to comment Share on other sites More sharing options...
