2007 F150 right at 100,000 miles
Customer did 3 tanks prior to plug change with 2 bottles of techron cleaner/additive
Engine was normal operating temp, with about 30 minutes cool down before working
Impacted them out using Makita electric impact on 1, 2, 3, 5, 6, 7, & 8 (#4 was done by hand)
Removed air filter housing, and intake tube
Removed bracket for intake tube, drivers PCV hose, and EVAP purge solenoid for clearance issues
Removed PCM bracket, and laid PCM forward for access to #3 and #4
Tools of significance
9/16" Long socket with 3" extension. Also used a 1" extension as well
Makita 3/8" Anvil 18v Impact
And VICTORY!!!
Also the white rubber boot seen in this last picture was found inside #7 spark plug well. Below coil, above spark plug, but some how not blocking continuity of the coil. I couldn't get the spark plug socket to get seated on the plug, pulled it back out, and the rubber tip was lodged inside the socket. Seems like its been there since the factory built the engine....
ETA: 55 for 56

04-08-14 8 of 8 on Coworker 2008** F150 98k. I put in a 20gallon treatment of Techron a week prior
04-18-14 8 of 8 on Cousin's 06 Fx4 68k (TXGSXR1K) had pinging under WOT between 3500-4500 RPMS
*I also no longer take the intake filter housing off. And I put the Makita straight on the spark plug tool on all 8 holes for extraction.
**My coworker's 2008 was built one week prior to the updated head/plug design.
