Well i trying using them before but my car run like **** and its not like i never change out spark plugs before on my car or other people car but when i put them in my car was misfiring like if i think was running to lean... so when i pull them out i saw they look like it was running to lean but when i return them they said one of them was broken so im not sure it was cause of that they run like that...

but i was wondering if anyone else run those on there car and how it go... just wondering if i had bad ones or maybe i did something wrong cuz i didnt have a torque wrench but i know the rule of thumb

 

your better off using oem sparkplugs, the plusestar plugs arent going to work better. and they could definatly make it misfire

 

did you check the heat range on the plug??

 

I was planning to get some but when I went and did research I could not find a single forum talking good about them. Every forum has like 1 guy saying he likes them and everyone else saying they are a waste of money and don't live up too their claims.

 

yeah i was reading about them too and i actually when out and bought them but they cause my car to misfire but not sure if it was cause one of the spark plugs was mess up when i bought them or it got mess up when i put it in my car.. so im still looking if anyone try them

 

actually i havent check for the heat range maybe that could be it but i ask it for my car but like i want back to NGK

 

sounds like a gimmick to me. NGK V-power copper plugs fo' life!

*edit* I probably need to change mine soon....

 

^x2 NGK V-power copper plugs fo' life!

 

so anyone else try them
