Worked perfectly in 2001 Cadillac DTS. No more miss fire. Replaced plugs wire boots and coils. All the same time and no more misfires. Just a dab of dielectric grease on these and you'll be fine. Too much and you will get a misfire!

Replaced the old boots during the replacement of my plugs on my 2003 DTS. They are working just fine. Might need to add more spark plug boot gel.
