Hey guys,

I have just installed NGK IX Iridium spark plugs... It took me about 40 minutes, most of the time devoted to the damn three plugs in the back.

I was wondering how do i know if i have installed them correctly? The engine starts fine, no warning lights, and tested on the highway till 100mph so all cylinders are firing good. I guess I am a little paranoid.
The car does feel better since the OEM NGK plugs were horribly eroded.


Am I too paranoid? lol.. thanx.

 

ehhhm, yeah you are. If the engine started out good withought any missfires then you did a good job...maibe because you took so long and did it carefully. I just dont see how you would feel the difference, maibe its the paranoia. The only way you'll feel a difference is if your old sparks where over 50kmiles old, other than that, it should be a 1-2wph hehe...
