I don’t remember where I saw the link to this guys paypal. but I found it one night and said screw it i am going to see of these things do anything. Well all i can say is wow these make the response of the H3 so much better. The engine doesn’t shake as much either. Keep and mind I also have the PCM of NC so of you are going to get these that could make some difference. They are super easy to install you literally just pop the springs out of the rubber boots and attach the copper piece to the coilpack and then put the boot back on then put it on your spark plug. Also I notice that when removing the springs a few had oil on them. is that normal or does that mean i have a issue somewhere? oh they were $55

 

Those are the solution to a nonproblem. Kinda cool too.... They should do no harm, but they aren't going to produce a measurable improvement either. Like fancy aftermarket spark plugs..... super duper somekinda brand....., do the same job as the regular ACDelco plugs they stuck in the motor at the factory.

If it makes you feel like you made an improvement then KUDOS!

 

Copper is not the proper metal to use within the elements for conductivity! I'll stick with my silver springs.

Guess you missed............ they are made of Beryllium copper. Different animal behaviors for different environments.
