Now let's see.... The Lightning has factory Platinum plugs that will last for 100,000 miles. Has anyone ever heard of a Lightning or a '97 and up F 150, for that matter, that ever had a miss because of a worn plug? Coil packs, yes - plugs, no! Doesn't make a lot of sense to me.

I don't know, perhaps that is for normal everyday driving, if you want the very best ET right down to the last 00x of a sec,

new plugs ... BUT you make a great point.

That is why I read this site, I get all sides and learn alot, and so far have NOT wasted any $$$.

 

Speaking of Plat Plugs, Nitrous and X-tra boost guys beware.
Run as far away from platinums as possible, if you are running nitrous.

You mentioned in the other post to change plugs to Bosch 4 at 30,000 miles. Is this what Mike has suggested? A while back I called Bosch and they had no plug for our engine and had no plans to make one specifically for the 5.4 S/C. I'm just wondering if you have a part number for them?

Thanks

Yes that what Mike told me this AM,
as I have only 10,000 on my BOLT I put it away for reference. Perhaps you can contact Mike and find out what he is talking about.

Sorry,
I don't have the exact answer at this time.

 

Thanks
I'm going to send an e-mail to him about that and some shanges I requested for the pos 1 on the TRAC chip.

 

Amen, Silver.

 

I guess the point of this question was to be able to get a better plug for performance. Maybe some don't thinik that the +4's are better, to each their own. It seems as if most people would try to get the most performance for their $$$$$$$$. Even if the plugs we have are plat., doesn't meen the are the best plug for performance, but maybe longevity--100,000 miles. If this was the case, we all would have bought just a K&N flat panel filter with their "million mile warranty" instead of something like an Airraid or Sal's setup.
