Just wanted to know what do you guys suggest on what spark plug to be using on an evo 8? Only thing major is exhaust, intake and meth kit.

 

i like ngk coppers br*es

you should stay at the stock heat range so ngk br8es. change them every oil change

 

I too like the NGK BR sparkplugs. For high boost on meth I'd go with the BR8ES gapped at .022"-.024".

 

If you're using meth, use NGK BR8ES because that will cure for high boost and you won't have problems.

 

thanks for all of your feedback

 

I use BR8ES gapped at 0.28

 

damn your spark tech COP and your .028" plug gap *shakes fist*

 

0.28" is way huge, didn´t you intend to type 0.028"? Right now, I am running BR7ES´s set at a wide 0.028" on pumpgas at 23 PSI. I feel that even for my pumpgas application 0.028" is a bit wide and I do mostly high speed highway driving and very little time spent at idle or or in traffic(I shut off the motor at red lights).

I normally run the BR8ES set at 0.024"-0.026" for highspeed driving on pumpgas. If I ran Meth injection I would go with the 8´s or even try the 9´s with a really dinky gap for my type of driving. I think that the 0.028" gap is a bit huge for meth with the stock ignition system. But, I am probably wrong since I´ve never run Meth injection on my Evo.

 

Yes sorry miss typed, .028 at 30psi on pump.

 

soo can anyone give me a link so I can buy them and another question is why purchase these spark plugs that only like 4 a piece and not the ngk iridium its not going to mke a diffrence?

 

So far, have used several Makes of Sparkies ... & satisfaction guaranteed for NGKs ..

Iridium Densos -- give it a miss if possible. Reliability in question.

Iridium Grex/Trust/Greddy L 7 Racing -- good (hvwr, Greddy filed for bankrupcy recently)

HKS -- duh ... basically NGKs ...why pay extra for the HKS name print on NGK product ...

NGK BR8EIX & BR9EIX - reliable good for street

NGK Racing R-7119-8/9 (fine wire. Super cold) --- good for track/drag and dyno runs ..(Currently on these)

A friend mentions that he was on the SilverNology sparkys ... similar results to the NGKs ...hwvr can't comment on them because personally have not used them ...

 

so can i get a link to buy them?

 

i have worked on a lot of evos what i us is bpr8es gapped to .020-.023 and had great success i have tryed the br8es but for me it looks like it does not burn the fuel of fast enough from on the of throttle

 

ngk

 

then whats the diffrence between the regular ngk spark plug then the ngk iridium everyone is suggesting the regular ngk spark plug then the more expensive ngk iridium
