Hey guys I am currently running NGK TR6 plugs. I had them installed back in March when I had the 6#er put on along with the dyno tune.

Back in July I had to replace one due to a fualty COP. I replaced both of them, the COP and the plug. My question is...how often should I change the plugs out in my truck?

With these plugs it idles a little rough...every now and then you feel a slight miss at idle. If I go WOT it dissappears. Is this a common thing with these plugs? And will it affect my WOT without me noticing it?

Any help would be appreciated!

 

i change plugs in my vechiles once a year to ever other year.. your wires and plugs wear out over time

 

motor craft platinum plugs work the best that i have found not sure the part number but go to autozone or o'reilys or what ever part store is your neck of the woods

 

Idle roughness can often be a dirty or worn Idle Air Control Valve. It may cause your L to 'die' when at idle rpms but has no effect above idle rpms. Easy to remove and clean or replace.

With no engine issues, I doubt if you need new plugs this soon. Mine lasted at least 60,000 miles.

Gen II Ls have no plug wires...........
