January 31, 2007Well I just ordered the new Halo Plugs. I 'll have to let you all know if they make a difference. They carry a 90 day money back guarantee, so I figure all I can lose is a little in shipping.

January 31, 2007Plugs either work or they don't. Any properly gapped plug in good shape will make your car run sweet.
February 1, 2007yeah yeah yeah. I've seen reports from actual users that say different. And I have seen differences in different plugs. Like I said 90 day money back guarantee. We'll see
February 1, 2007So have these differences been noted by a butt dyno or have there been before and after real dyno runs to see any gains? I'm not trying to upset anybody, but I deal with real world, proven performance gains. Good, properly gapped plugs will allow your vehicle to run with full efficiency, but will give you no more than the sum of the parts you're running with and that's still a good thing. They won't add extra performance.
February 1, 2007Someone on my Ford Explorer forum replaced some relatively fresh platinums with these and gained 2 mpg. He claims his dad helped design them. He was reluctant to try them (you know how teenagers can be) but dad convinced him to try it. The website doesn't just boast, they post what are supposedly actual results from actual users. That's not something you normally see.
Don't know about power, but then that's not my goal either.
The idea behind them (if you haven't looked at the site) is to expose virtually all of the spark to the fuel with nothing being shrouded, therefore getting a more complete burn.
If there was nothing to it, then racers wouldn't bother with indexing.
February 1, 2007I wish you luck. I fail to see how you could set a gap on those, and the idea of a ring of spark, while appealing, is counter to what I know, in that the ring cannot be perfectly equidistant from the center post, and the spark will jump from the closest point on the ring to the center.
Doesn't mean it's a bad plug, but I am really skeptical about a measurable benefit.
Certainly can't hurt to try.
February 1, 2007Setting the gap isn't an issue. they come pre-set, just like my NGK iridiums did. Told me right on the box not to attempt re-setting for fear of breaking the electrode.
I know about the equi-distance and path of least resistance and all. I work with electricity every day. Even if it were equi-distance the spark would still pick one spot which may change from spark to spark.
What it does do is un-shroud the spark and allow more of the fuel to "see" the spark.
If I don't see an improvement in mpg I'll send them back.
February 5, 2007I got the new plugs in. It actually tells you to dis-connect the battery to re-set the computer so it learns the new pluf faster, which they claime fires faster. Didn't remeber reading that part.
Anyway I plan on doing this right so I can see somewhat scientifically if they make a difference.
I'm going to run out this tank of gas (cause I know it has ethanol) and get a fresh tank of non-ethanol. Do a mpg test and depending on how cold it is I'll do a few 0-60 runs. Then install plugs. Give the computer a little time to learn and then run the same tests. So it won't be a "butt" dyno.
February 5, 2007Then check mpg for at least 5 tankfuls. Checking mpg on one tankful is useless. Too many variables. 0-60 runs won't tell you much. Do a before and after dyno run to see for power increase. Without using a dyno you are still using your butt.
February 6, 2007I don't get the "The idea behind them (if you haven't looked at the site) is to expose virtually all of the spark to the fuel with nothing being shrouded, therefore getting a more complete burn."
A conventional plug has 1 curved electrode and a center post electrode.
The halo has 3 posts to hold up the ring - how is that better?? The three posts would "shroud" more than 1 post.
Whatever. Can't hurt to try.
February 6, 2007true, but there is nothing under the electrode. That part is completely open because of the ring. I would they could have accomplished this with only one piece coming down, but maybe there are other reasons for it. I got the plugs and the the electrode is pretty stout. More than I expected to see. Not sure if that's good or bad. They say they fire faster than a standard plug.
February 18, 2007Plugs are in. Now we'll see if they make a difference.
I cleaned and re-oil my K&N filter too so that may effect the outcome, but it needed it. I should do it more often. I wish I would have thought about it b4 I changed the plugs. Oh Well. When i modified the intake and put the K&N in there I only got about 1mpg better at that time. So the diff shouldn't be more than that for the filter anyway.
After I installed the plugs it ran really rough and stalled a couple times until I got a couple miles on it. Now it's as smooth as it was b4 They tell you to dis-connect the battery so the computer can learn the faster firing plug sooner (at least that's the claim) So I'm sure that was a factor in why it ran rough at first.
My mpg prior was averaging 20-21 with one oddball tank around 24. Otherwise it's pretty consistant at around 20-21
I ran 4 0-60 runs (that's b4 plug change) at 11:07, 11:05, 10.81 (probably my bad) and the 4th at 11:00 even I'll give it a week or so b4 I do that again.
