I have looked at several sites on how to read spark plugs. but it wasnt really helping,they just ad extreme cases of this and that..
Sorry that the picks arent that great, i took them with my pc.
Here's the "mods" list.
*fmic. 2.5" piping/tb elbow
*bs delete
*bc 272's, bc springs & retainers
*arp head studs
thats pretty much it.
I'm running 12blbs of boost. the plugs i'm using are bpr7es.
I'm also running the stock 1g maf, bov is recirculated.
not sure if any of that info is needed but yeah
..
cyl # 1 & 3 have a white strip across the tip of the ground terminal that goesabout 1mm down, from there it's a grayish color down to the threads with a little bit of white towards where the ground terminal meets the threaded part.
on plugs #2 & #4 the ground terminal is gray, no white on the terminal.
on all the plugs, the electrode is white for the most part.
The bitch runs HOT btw! It never gets to the red or even close, but it runs hot. I dont like it..
