What is the NGK stock Number for a plug one step colder than a BKR7E? Thanks in advance.

s# 4554
p# R5671A-8

 

It's not BKR8E?

 

i don't think there is such an thing.

 

i think sparkplugs.com has all the listings for ngk plugs

Ndogg,

Do you run those? If so, what's your take on them?

Phil

 

i don't run those yet. when i finish my build i will be running the same part number but the 9's. i got those from searchin this board... jason hunt, "mase", others recomended these.

R5672A-8 is another plug you could use, Stock No. 7173 you can get that plug pretty cold.

I just picked up a few sets from rockauto.com (enter "209526191361" under "how did you hear about us" line at checkout for 5% off until june 7)

 

R5671a-8(sn 4554) VS. R5672a-8(sn7173) What is the difference between the 2 and does anyone have any real experience w/ them? Gap you are running, Boost level, fuel etc...... Thanks.

Phil

 

the diff (from looking at ngk.com) is the tip protrusion. the r5672a-8 has more.

 

everybody likes pics.... here is the R5672A-8 on the left/BKR7E on the right.

 

Thanks HPFSI . Doesn't look to be a very big difference in the tip protrusion?

Phil

 

externally they are identical - the BKR7E's are a "projected tip" plug as well. The #7's just have an insulator that extends a bit deeper inside the plug due to the temp. difference

 

are those 8s on the left resistorless? it should say non-resistor on the front of the box...I know the 7s ahve resistors

 

yep they are the "racing" non-resistor plugs, doesn't say it on the box but yeah I guess v-power plugs colder than a 7 are without resistors which isn't a problem.
