screaming eagle plugs

I am changing screaming eagle plugs on my hi compression motor. (#32186-10). I was told to gap them @ 040. however the box stated they were preset @ 035 for that particular part number, Other than the difference of 005, what would be the difference performance wise?

None that you could see or feel. Gap 'em at .035. Too large a gap and you'll eventually get performance degradation.

you will see a difference. Might not be in the power itself but how the plugs wear over time.

Good question why SE plugs, im sure they'r more money.
As for the gap you can split the differince at 37.

I went from 120 miles a tank full to 180 miles a tank full. So I'm sold on them.

Just because the box states its preset to .035 doesn't mean they actually are. I very rarely get a set of plugs that are in their pre-gapped state. So double check with a good gapping tool before install.

If your talking about a diff in performance depending on the gap, I don't see how. If your talking about a diff in performance based on indexing, I also don't see how. Both are controlled by the laws of physics.

You won't see a performance difference with SE plugs over standard. Only difference will be in your wallet. I've used Autolite spark plugs in my bike for over 50k miles without issues. A lot cheaper, and better quality then HD's.

I seriously doubt a 60 mile difference in milage was caused by changing your spark plugs. That would be a 50% improvement. Or 24 mpg before the SE plugs and 36 mpg with the SE plugs (with a 5 gallon tank). More then likely your old plugs were just shot or you aren't drag racing from stop light to stop light as much anymore. Just sayin'...

My opinion is that your wasting money on the name for these plugs. Im sure the Mothership gets them from another brand company. I have used NGK and others with the platinum or irridium centers and have had no issues....they burn well, last a long time

you'll find that most plugs come pregapped at 035, even for cars, it's seems to be the standard gap. se plugs only cost the wallet more, can get the same plugs from any auto store a heck of a lot cheaper. gap them according to your maintenance book. hd plugs 9 bucks a shot, autolite 2 bucks a shot. just my 2 cents worth.

the 6R12 standard plug is 3.50 each. SE are 4X that price, and a waste of cash.

Back when I was racing stock cars the big thing was indexing the plugs. Probably wouldn't make any difference on the smaller engines but, the big boys do it all the time and they make sure they are gapped properly.

Well, if his wallet is lighter, wouldn't he go faster?

That is a bit hard to believe.
