Does anyone have these? Are they good and worth the money? Thanks!

For how expensive they are and how little the gains are it's pointless unless you are building a drag/race car..

 

Waste of money. Your stock setup can support alot of power and adding so called better ones will do little for performance.

Want to actually go faster? spend that same amount on a nitrous kit and you will actually make power.

 

I see GMS in the web adress and refuse to click. Waste of money.

 

Stay far away from GMS. Stick w/ MSD, Accel, or Performance Distributors if you need the better spark.

 

GMS is junk! I learned the hard way...............I bought the COP set for my 99 GT. It cost $400+. I installed and the car ran like crap. Put the stockers back on and it ran fine. I was getting a pretty bad misfire with them, so one(or more) must have been bad.

 

GMS = no bwaynoh
