Hmmm...now that's interesting.........


The 14F's aren't listed in the catalogs for some reason, I was told by the Hotline to start installing the 14F's...........

 

Bamorris...where did you get your info on the heat ranges? I was searching around a bit and haven't come up with much....from what I have read the 14F should theoretically be a hotter plug.....the longer the insualtor the hotter the plug.....

 

This site says the same thing.Half a heat range hotter then the H1 and half a heat range colder then the H2.You did say the HT15 was the same as the PZT-14f?

Fordtech1, do the PZT-14F's have a nickel plated electrode shield like the Autolites? It says it helps with corrosion protection.

Would it be possible to tig weld the shield where the crimp is to keep it from coming apart?

 

IIRC, it was either Quintin or i.ride.suzuki who initially gave that info. The idea was that the original plugs were the PZT-2F's, but they were having some pinging issues. So Ford started recommending their already-in-production colder plug, the PZT-1F... In the meantime, they developed a more suitable plug, somewhere in between the 1F and 2F...

At least that's the store I recall hearing... and like chapdog said, it seems to be confirmed by the Autolite-branded offerings.

 

I have my champion plugs in hand and about to go on an adventure that not many have been on.. To change the plugs for the first time on my 5.4L 3V '04 F150crew w/91784 miles. Wish me luck, I'll let you know how they run if I get to keep the head's on the truck today.

one last note I made a tool like the one that the ford dealers use. got a 9mmx1 bolt tap and made a 6" long SS rod that I threaded 9mmx1 to use as a puller.

 

I was wondering the same thing, looks simple enough.

 

I got a tig set up in the garage. someone give me a plug and we can find out.

 

you should not need the tool if you only have 10k on the truck. near 50k on my 04 and the plug change went fine. good luck (you shoun t need it)

 

I believe he said 91,xxx miles, not 9,xxx miles.

 

ops. sorry, my bad.

 

I can't wait to see how the Champion plugs work. The wait is killing me.

 

same here. I just recently put HT1's in mine and wish I would have held off a few weeks to see how these work out.

 

Well, I am very interested in the new Champion plugs as well. I did my original plug change at 55,000 miles (sprayed a little WD-40 on the plugs during removal) with no issues. But, hearing that many have had challenges, I am going to swap out to a one piece design now to avoid any futire challenges.

I do have reservations about using Champions, but these are double platinum, and all the Mopar muslce cars used to come stock with Champions, along with just about every small engine that I have worked on (e.g., lawn mower, weed wacker, snow blower, etc.), so they are supposed to be a decent plug.

I will post after I do the install (I ordered them last week but they are on backorder and will not ship for ten days or so).

 

WOW, you have a set to go changing plugs on an 04' with over 50k with only WD40. I'll hand it to you, you're braver than I am. I'm still under 50k with an 05' and can't conceive trying this myself, esp. with the problems people are reporting. Did you do anything different besides using WD40?
