I have a 2008 in need of COPs and I've notice that many people have recomended getting the aftermarket DG508s on ebay however I didn't see any posting that were specific to the 5.4L 3v. Have any of you used them? If so, any advice, recomendations etc...

 

i used accel coils and they have worked great thus far...

here is a link to them on amazon which has them for sale for an awesome price!

 

You need DG511's, the DG508's are for 2v 5.4's.

Preferred Ebay vendors are Global Automotive and Uneek Supply.

 

Thanks guys!
I've used Accel products in the past usually with great success. Is there a noticeable improvement with the Accel coils? Also I've noticed that the Rally Coils use the same codes and look the same. Does anyone know if they are the same or if they are comparable?

 

Reliability is the main concern with COPs as nobody likes to be stranded. Many have used the ebay ones and have had a low failure rate. This isn't a 1960's points/condenser system with spark plug wires. There is very little (negligible) voltage loss with COP ignitions. You likely wouldn't gain anything at all from using one coil over another. If you had forced induction, and were running up against spark blow-out from the swirling intake charge, then you might have to start looking at different or higher output ones.

 

Very eloquently stated Otto. Thanks again!

 

is this the same coils for a 2006 with the 5.4 3 lt or does it take adiffrent coil

 

The 2 Valve and 3 Valve use 2 different coils.
