Got some water in my 2k expy 5.4l. Thru p0301 p0303 cleared up after some blowing and over night sit.

Want to change the COP and plugs. Has anyone tried the high output COP and what suggestion on plugs or stick with motorcraft?

Thanks
Robert

 

MC & OEM cops

 

Motorcraft if you can afford/get them.

I needed to replace more than half mine and I was unemployed so I got the visteon COP's.

They are working so far.

I had Global before them and those lasted 3 years until a joint in my coolant line soaked the entire engine and carboned up all the COPs.
