I installed the magnecor plug wires a while back. Before I installed them I read about others having problems with the wires coming loose. If you really push and take your time they will snap onto the spark plugs. My question is at the coils. I installed them with the coils off the valve covers because you have to really push. I never heard or felt the click so I tried again and found if you push very hard, they will snap in place but just barely. I have concerns that they will snap off while driving.


It seems the possible problem is the boots are just too thick. The boots on the top and bottom coil connections rub and bind up to each other. Has anyone tried trimming the outside rim of the plug boots to make them fit better or any other tips to keep them secure?

 

I believe the issue is that they never got the click in the first Place. I have never seen none pop itself off so long as it was initially clicked in. yes turn off the radio and listen/feel for the click as it is quiet.


yes i have discussed their fitment with magnecor several times throughout the years and I promise you that they fit a whole lot better now than they did before due to me driving coil packs out to their assembly plant for them to use for verification on boot sizing. the rubber boots that contact each other are flat cut and line up next to each other once they are in place. they are not angle cut and thus pressing each other upwards. in a perfect world I would like the boots to be a little thinner at the base but I am content with the way they are now and believe the positives of them outweigh the negatives over the oem or other aftermarket wires.

 

Hey Rob,


I was hoping you would weigh in, your inbox is full. When I last installed them I got the click on all. I installed the bottom ones first, then the top ones so the bottom ones are basically being pushed into the coils by the top ones but the top ones just barely clicked. That's why I'm wondering if they are going to pop out of place with the engine movement. They have a fatter lip at the very end that seems to be rub. Do you know if anyone has ever shaved the boot a little just where they rub and ended up with a more secure connection?
