    Anyone running these? I replaced my cops about 3 months ago with a set from one of the performance stores...they didn't have the Accels so I bought their version the blue ones. What a terrible product! Within 3 weeks the first one fail, a month later another one and now a third is on its way out...just waiting for the stang to throw a code so I know which cylinder is missing. I'm glad I kept my OEMs but I know one of the six I have left is bad, I don't know which one though.

    That being said I think I am just going to replace them all with the new WeaponX cops. I've been reading all the the post and the owners/developer have been posting on al ot of the forums and seem like they are really committed to making a good product that has some legitimant R&D using the newest technology.

    Anyone running these? I am really interested in their reliability so let me know how long you have been using them. Thanks Stangnetters :hail2:

    Would your blue ones have been Moto Blue from the famed RPM Outlet? I know the Accel ones and MSD ones are good. I havn't heard much about the Weapon X ones. Also, stay away from the Granatelli ones.

    If you aren't having any failures with the original COP's what is the benefit of replacing the stock ones? Is there any improvement in HP?

    unless you are running high boot or spray, the gains are not worth the cost.

    Weapon X flat out rocks....awsome company that does a TON of R&D. They design all of their own products and are top notch quality. Alot of cobra guys use them...over on modularfords the owner posts pretty often in the 03/04 cobra foums.

    I would look into their spark plugs as well...

    Yeah, the blue ones are Moto Blue...a real waste of money. I've read all of the owners post over at the modular forum and was impressed. Definitely a lot of R&D. I'm ordering the cops and plugs tomorrow.

    do a google for reviews. if you find little feedback you should probably consider an alternative.

    Maybe if you were not so cheap you would have bought a better COP and you would make more horsepower!
