Removed, and re-antiseized all plugs yesterday. socket/extension worked great.

Im thinking about picking one of these up. Id like to do my spark plugs before winter.

milage ?
 

hi , how many miles are you changing the 5.4 plugs @ . Bud

The dealer told me they are recommending changing them at 60K miles to minimize the chance of breakage. Trent changed his around 60K (Trent you can chime in with the actual mileage) and had some break.

I think it was around 65k and 5 out of 8 broke.

Thanks Trent!
