GEN 2 Spark Plug Change - How Often?

[mad man]

Not being funny. Compare part numbers on the two plugs.

Bingo one of the plugs are a CYFS12YRT3, That’s the oddball., all the rest of the plugs are CYFS12YPCT.
About 10,000 miles ago the dealer had to change one of my coil packs and replace one of my plugs, under warranty .
WTF.

Be thankful its not a plug change like on the 5.4 triton lol.

Change the boots while your in there also its like an extra $50.

Been known to notice such things on occasion. Also, more often than not, the most simple answer is the right one.

I change mine every 25,000. They are not expensive. And I want all my cylinders working right when I'm running from the law at 230am high on life dressed like santa claus's skinny cousin, Banta Balls.
