The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition. In engines like this with one coil per cylinder you can diagnose a coil by putting a timing light on each one to make sure it is lighting the light consistently.

Price, Wow!
My 2003 f150 XLT Supercrew 5.4 Triton. it blewout #8 Sparkplug can't complain it has 175000mi
I orderd the coils and plugs. $115.00total.
avg local per coil was $60.00 I paid $65.00 for 8 pc kit! I used a Lisle 5.4 triton repair kit. It only took 30 min to thread and install #8 plug!
I gave 5 stars But4.5 is closer. only due to shipping. took couple days longer due to parts shipping from different warehouses. Still beats Rock Auto hands down only one shipping charge! order from R.O. your charged per warehouse? 5 parts 5 warehouses 5 charges? WHAT!

ignition coils
I haven't had any problems with my coils yet they have given me a great performance so far. I would purchase them again for certain because of the price and the quick deliver to your home. I am hoping to get good performance out of them and if I do this is the place for me to buy parts for my cars.
