spark plug options
I'll be doing the spark plugs on my 05 (43k) in the next week or so. What options are out there for plugs? Would really like a one piece design, but care more about performance. It the best one is two piece than I'll just pull, clean and gap it every 10k.

if you DONT have a blower the autolite Ht1's are awesome. restored a few lost ponies when i switched around 50k.
if not then stock is always a great option, but whatever you do make sure you put a small amount of anti-seize on each so you dont have an issue with them getting stuck if you change em again at higher mileage.

I had Pierre install Autolites at 50K. I didn't want to mess with the spark plugs incase they broke. He got them all out with no problem.

Are the HT1s a one piece plug or two? Ive read that champion makes a one piece but its pretty much crap. Is this really the only options, autolite, champion and motorcraft?

Don't forget that FRPP makes a good plug, as well. I run FRPP's 3V0 plugs in my supercharged 07 GT. 3V0's are one heat range colder than stock and are copper, which is ideal for boosted or high horsepower applications.

So Id be looking for 3V1s? They are only availible through the dealer right? I will have to check the pricing on these two. Looks like new plugs then pull and clean every oil change. Thats just for a car these days. Guess this is where Ford dropped the ball on the 05s.

I don't know if FRPP has a 3V1. Never heard of them. However, the 3V0's are ideal for modded, naturally aspirated motors - not just boosted motors. Keeps cylinder temps down (so you can get away with more timing and more aggressive tuning) and copper conducts electricity waaaaaay better than platinum (they just don't last as long). You can buy 3V0's from quite a few vendors - not just Ford. I paid just under $100 for the last set of 8 recently.
Here's a few places that carry them. Click to see their ads....
Ford Racing
D'Agostino Racing
Jeg's
GEF Racing
Late Model Restoration
And there are countless more, I trust.

Brisk Racing Plugs are what I use....DAGo stocks them, Blow by stocks them...probably a few others too...they are a silver core and traditional electrode...they are around $15 each...and not 2 piece...they offer 3 or 4 heat ranges...my car likes them, only neg is they wear out sooner than others being a silver core.

I put in the Champion 7989 plugs about a week ago. I've got around 450 miles on them now. I inspected the before putting them in due to some of the quality issues that have come up. I think if they look alright initially they should be good. I have 48K on the car and pulled and cleaned up the factory plugs at 18K and 35K. No problems with them at that point and I didn't need to use any penetrating oil. To me they are the only long term viable solution that doesn't require over-maintenance. I'd like to see some NGK or Motorcraft plugs in a one piece design but it wasn't something I could hold out for. These Champions are definitely better made than the normal 2 dollar copper ones you will normally see.
