They are under the coil on plugs. Right under the fuel rails. |

just remove the small bolt that holds each coil down and then the plugs are directly under the coils |

Unless you've got a diesel or a methanol engine in that mustang you've got spark plugs. |

Remember to blow out the spark plug holes before removing. The 4.6 spark plugs are straight up and are bad about collecting grit in the bottom of the holes. If you don't clean it, the grit will go straight into the combustion chamber. The results is a "smoker".
When re-installing the torque is 11 foot pounds. That is not much torque. Best not to over torque. A little anti-seize on the top threads near the seat will make removal easier. Do not get anti-seize on the lower threads or the tip.

Be glad it's not a 5.4 3v. I've been changing the spark plugs on a friend's 05 F150 for 2 days now. They break apart in the head, and I've had to use a specialty tool to remove every single one of them so far.
Just watch when you are torquing the new plugs down to not angle the socket. It's very easy to crack the porcelain on the new plugs that way. |

Dude its easy. Remember to blow out the plug wells like was said.
What plugs did you get?
The vehicle probably has platinums which Ford says will go 100,000 miles. Does this even need to be done? |

Just watch when you are torquing the new plugs down to not angle the socket. It's very easy to crack the porcelain on the new plugs that way. | on the 2005+ 3v there is a TSB regarding this. The chances of removing the plug without breaking is greatly increased if 35 foot pounds is not exceeded during removal. In that case, spay pentrating oil and wait. Remove 1/4 turn, tighten 1/8 turn all the while not exceeding 35 foot pounds. Add a small amount of spray as it begins to come out.
Following this procedure makes a HUGE difference. The chances of breaking a plug much lower. The key is to wait for the spary to soak in while working the plugs back and forth. |

Seriously, if you can't find plugs on an engine I'd seriously question the wisdom of turning wrenches on it once you find them... :| |

you got some sweet dyno numbers on the saleen clone, but the modular engine is one the easiest to do plugs on hands down. just take your time make sure theres no trash around the plu holes before you remove the plugs |

All you need is a little TLC (Tender Loving Care). It's your car. Don't beat up on it... take care of it with concern not anger. |
