okay i was wondering about replacing my spark plugs??? i read that if you feel like alot of fuel isn't being burn't meaning i guess back fires and hard starting is a way to tell when spark plugs need to be changed out....

i am considering brisk or ngk...i wanted the best spark plug so that way i won't have to buy as many...i also heard that the brisk spark plug will give a hp gain of 1.5 hp...that was from http://www.oppracing.com

haven't heard much about ngk and iridium plugs...can someone enlighten me on what to expect from a high performance spark plug and what would yield the best performance???

I prefer NGK.

 

thanks speed i will go picks some up...i am tired of misfire...and i can tell when those plugs are worn out...becuase not only on cold starts but on some starts hot it is hard to start....

can i use regular engine oil on the threads when installing them...or should i use an antiseazing oil???

 

NGK!

 

I JUST CHANGED MINE AND GOT 10K MILES OUT OF NGK CR9Es AND TO BE HONEST I DIDN'T NEED TO REPLACE THEM I JUST HAD EVERYTHING APART AND THOUGHT WHAT THE HECK. I COULD HAVE GOT THE IRIDIUM ONES (CR9EI) BUT I HAVEN'T FOUND THAT THEY ARE MUCH BETTER IF YOU'RE ONLY ON THE STREET. HAVE FUN!!!

 

Heck I have almost 18K on my stock plugs but it's time to replace them. I'm going with the CR9EK's.

 

well i have like 22k miles and i don't think i have changed out my spark plugs once!!! i think i will get the iridium ngk plugs[]

 

ive always changed my plugs every year or 2.
