Will these work in our cars?

[THE STIG]

Specifically a 440, has anybody ever used them, any feedback?

havent tried them, saw on a show they dyno'd on a SBchebby giving it 10 more HP.  I have heard that individuals with non-custom pistons should pay heed to electrode to piston clearance as the E3 plug is longer than most OE plugs.  But, I have no irrefutable hard evidence suggesting this is the case.. it is just hearsay, so take that for what it is worth.

Go back and look at how many plugs of this type were marketed over the years with all kind of claims,Split Fires,Fire Ignitors and a host of others.Where are they now? Sort of like the Triple Edge wiper blades with a lifetime guarantee.

The "what's the best spark plug" issue has come up a lot here....My opinion?  Well....what's going to make the difference is the ignition system itself, thus needing a higher dollar plug....but if it's a bone stock ignition?  I don't see the difference between let's say an NGK plug, or one of these newer type plugs....The spark is only going to be as strong as the ignition is rated for.   In other words, the spark plug itself isn't going to increase the voltage any. Not to mention the fuel you are using which makes a difference also.  Now...if you use, say, a Mallory or an MSD setup for example, then yes, I would look into a better plug to accommodate.  Others may have a different theory, but I've done a test with basic Autolites  and then installed split fires, and I didn't notice any difference in performance.  Alot of the issues today are, that the fuel at the pump is no where near the octane rating as it used to be when our cars were new so it can cause plugs to get fuel fouled since in some cases the crappy fuels of today don't burn as complete as they should.

You make some good points here, especilly when you consider that these plugs cost 6 bucks each, but even if you do have the MSD ignition will these even work in the older engines? The pimply faced kids working at the various Auto parts stores have different opinion, yet I see Stacey David on Gearz putting em in all kinds of crap.

I'm very wary of any magazine or television show endorsment of a product.  If they weren't paying Stacey David to put them in there would he still go buy them out of his own pocket and put them in?

My thoughts exactly when I watch these shows.

Funny thing around here, the guys with the serious strip/street race mills use cheap-o standard style plugs. Why? Because they work pretty much the same, and when you fry a bunch while breathing a little too deeply into the nitrous bottle, you just grab another set instead of selling a kidney to finance new super-plugs-o-the-month...
I'd rather buy a good MSD or similar ignition setup, the difference will be noticable (which I doubt those plugs will be, ever.)

  see http:streetmachineclub.com  they did a dyno test on all popular plugs
