Im running NGK BR8ES plugs gapped at .23 also I have the sparktech non-CDI unit and I have yet to have issues also I go about 2-3 oil changes now with the better spark.

 

When needing wires I bought some Denso's off Amazon and they fit perfect and also worked great. Not a bad option.

 

I run BR8ES at .026 here and 130k mile coils. Wires and boots replaced once just as a pm sort of thing.

Never once have I had a misfire in my car even out to 30psi on a 61mm

 

Stock wires work the best short of a Sparktech system. Magnacore might be hotter but dont last as long.

 

^^ yea! i let mine sit for a year and they went bad. junk!

 

So looks like people are going with the BR8ES rather than the BPR8ES...since theyre a hair colder I guess it can't hurt on my setup?

 

well me i bought my evo with 26k on it and it had NGK plugs in it so i figured ill change them. i went to a performance shop and they sold me Denso IK31#4 and the car ran great and then sat home for a week when i was on vacation came back and couldnt drive the car it was misfiring on all 4 cylinders, i went back to the shop and they gave me a set NGK R5671A-8 and the car runs perfect

 

Picked up some of the BPR8ES plugs from Advance for like $2.25 a piece, changed em in the parkin lot and found out the previous shop put in BPR9ES's. I had a missing problem so I figured it was the plugs since I didn't know what was in them or the history of them so put in the 8's and still missed under load/boost. Did it for a day or two but since last night it has been FINE and completely back to normal so I have no idea what's going on, If I got on it hard once boost and load got up there it would miss like someone turned the key off, not sure if it is fuel or spark related, there would be no CEL after it so I'm assuming fuel?

 

I got some magnacor 8.5 wires for sale almost brand new for cheap. lmk what you think, thanks

 

I have had my magnacore's for almost 8yrs...Chris Black did tell me there was some fitment issues and stock were better. Then I heard magnacore redesigned the seats...its whatever though I am going to COP. Chris changed out my NKG iridium for copper version to rid my car of the misfire. The first time something got cheaper for my car, at less then $10 a set. Long story short Copper plugs, stock wires until COP.

 

I don't think my problem is the wires because everything, motor/trans/clutch has less than 5k on everything so would only want them if it was CHEAP.
Pm me a price if you want

 

pm'd

QUOTE=My03evo;9044104]Well, I got the car and tonight on a pull it misfired twice plus it's time to change the plugs since I don't know what the hell's in there. From what I'm searching I should be going with the BPR8ES or BR8ES...Debating on which one to go with.

Where are you getting yours for $6 for all 4?

Anymore comments on if I should go with the projected tip plug (BPR8ES) or non?[/QUOTE]

 

I get 4 BR8ES for ~10 bucks at Advanced or Autozone

My car 100% prefers the non-protruded tip plugs over the protruded tips both in the 7 heat range I use to run and the 8 heat range I run now. Smoother idle, accel, and look very uniform on replacement

Changed every 3-5k

 

I have the SpoolinUp COP and have no complaints what so ever. Quality part, works well, looks amazing, and is priced right.
