what spark plugs do you run in your evo?

 

We always use either the NGK BPR7ES or BPR8ES depending on the set up! Let me know if you have any questions with which ones to use!

this is my setup what do you think?
ACT HDSS clutch w/ OEM resurfaced flywheel
-Buschur downpipe
-Apexi intake
-Sparktech non-cdi coil-on-plug ignition
-CBRD short route UICP w/ CBRD battery tray
-Buschur 3.5" street FMIC w/ Buschur LICP
-Walbro 255 LPH fuel pump
-Hallman RX manual boost controller
- IX metal diverter valve

 

I've had success with autolite 63 copper. They're cheap too!

 

I got a set of plugs from map and I think they are the wrong plugs because they look shorter like the evo 8 plugs

 

What is the designation on the plugs that you have? Best to call MAP.

 

How much boost are you running and what fuel in your particular setup? We never used to run Autolite plugs in most West Coast Turbo Buicks back in the old days because they had a propensity to detonate compared to the preferred AC Delcos at boost levels over 17 PSI on pump gas. But, maybe I am comparing apples to oranges. However, at least, in the case of turbocharged Buick V6's, Autolites were just not where it's at. Of course, this was way back when....

 

Yeah, what Justin says! Maybe I would add the NGK BR7ES(my personal favorite) to his short list as well.

 

I also run the BR7ES.

However, the last time I was visiting CBRD, they advised me AGAINST using those plugs, and to go back to using an iridium plug like stock.

 

BPR7ES gapped to .20 E85 650hp

 

we only run Iridiums-

factory in evo IX, and evo 8 depending on the build- BPR7EIX or one step colder- sometimes non protruded-

cb

 

On gas, depending on the build you could go one step colder, on E though I run stock heat range 7.

 

Hi,

in my uk 8 mr running 400/400 i just fitted some ngk BPR8EIX, and dyno tested and mapped just after --- everything ok

 

I use BR8ES now. Used the BR7ES on the stock turbo years back.

My car has always preferred the non protruding tipped plugs. Never had a spark related issue on my car
