Should boot snap On the Plug./4.6 bucking.?

[chris kelvin]

Hey guys, not exactly a mustang, but i got 95 thunderbird 4.6l 2v and alittle while back i changed my plugs, the wires and ignition coil packs are in great shape...they are stock 8mm motorcraft wires. The plugs in there where motorcraft platinum, which where slightly brownish..normal wear pretty much. I put in autolite platinum plugs, cause i want them to last (stock was motorcraft plat's)... Now when i installed the plugs w/anti sieze and gapped to .054 (stock) i noticed that each boot simply slips onto the plug. IS IT supposed to snap on, to ensure a tight fit..? The boots coming off just slipped off also.

I'm asking this cause i get a hesitation/buck when the car is floored..it happens for a split second and goes away-alittle when the engine is warm. THIS happened after changing the plugs. The maf sensor is new, everything else double checked.

The fuel filter was changed a week ago, so that's not the problem. I used to put Chevron with Techron alot, like once every oil change......for the past 6 months i didn't put that stuff in, maybe it's the injectors..?

You can crimp those collars inside the spark plug wire boots so they grab the top of the plug tighter. Also, use a dab of silicone dielectric compound to ensure good electrical conductivity.

Thanks man..yeah i left it pretty much the way they where on the stock plugs, just slip on.

I'm gonna change back to motorcraft and make the connection tight..and use the de grease.

Also I think your plug choice and gap is fine...

As Mr. Trout recommends, the dielectric grease is a must.

Note that the boots will slide on the wires, they are not molded onto them. So, you can carefully push or pull the wire out of or into the boot so that the wire inside is the required length to meet the sparkplug tip. The wire should "click" onto the sparkplug tip if the metal connector is making good contact. Test fit each one with an old plug. When the wire length is just right in the boot, use a Q-Tip to swab the grease in the boot and onto the metal clip.
