About to do another tune up on my 06 5.4 and I bought the Accel ignition coils do any of you think that it will work or harm my truck going or more upgrades down the road and a tune but not just yet what are y'all's thoughts

 

I have heard mixed reviews... That's why I bought mine and returned them, but that being said, I have a 4.6, so my plugs are different and I assume the coils and cool boots are also different... I did NGK iridium could and plug boots, keeping my stock could, truck has never run better... My .02, keep the stock coils and at least make sure the plugs are in tight, if you don't wanna replace them bc I know how tough the 5.4 plugs can be, and just change the boots and springs

 

they will not hurt your motor.. they may not last as long as OEM..

 

....

 

Really no need to "upgrade" stock ignition components....

 

I have them in my truck and they work great. Used Motorcraft plugs. I think MSD makes COP now I would have went with them but at the time they didn't but I haven't had any issues with the Accels.

 

The Motorcrafts will outlast the aftermarket coils. However there is nothing wrong with using the aftermarket models mentioned above. There is no performance increase bybusing these. The stock coils fire enough voltage to support triple the hp stock motor makes and triple the cylinder pressures.

 

Thanks for the input everybody.
