Ive read their claims of increased power, milage, and plug life, but has anyone actually used them and can give an opinion???

 

no but I have the denso irridiums and no gains........

 

You are not going to gain much with plugs on a stock engine, You need to get into a increased cylinder pressure and timing mods to gain from a plug change.

 

Have you heard about the HALO spark plugs?

MPG went from 28 to 32 after a sweet install of these pre-gapped plugs.
70,000 miles is a long time for one plug, this one has unlimited places for the spark to jump. The split fire stock plugs have two places for spark to jump.
Two is better than one and an unlimited number is best.
Please try these before you dump big money into a questionable mod.

 

That is the same as the torque masters http://l-tunedparts.com/product/?id=1779 so it does give you a boost in gas milage...how about power.

 

Yes to the increase in MPG. Only one tank since the new HALO plugs but it was 32 mpg.
All winter I got 28MPG. Oxygenated gas is no longer required, (I think) and that may have contributed slightly.
I am happy. The original split fire plugs still had red paint on the tounge.
Power? No increase in G force (joke) You may not notice it, I hope so.
We need dyno numbers to be sure, but it feels good.

 

Ill have to give one of the two a try...thanks for the input

 

Marketing hype. No matter how many electrodes there are, the spark will only jump to one...

I say save your money. Buy good quality plugs and you'll be fine. If you feel like splurging, buy platinum plugs. But, don't spend crazy money on gimik spark plugs.

 

Agreed. Just do some google searching to see the results of testing on other gimmick plugs. And don't buy iridium or platinum plugs expecting increased performance. The only thing to expect from those is longer life.

Typically your best bet is standard copper plug from a reputable company like NGK or Denso. Especially if you would change your platinum/iridium plugs on the same increment as a standard plug. Save yourself the money and just get a quality copper plug.

 

I bought my Denso Irridiums for longer life,,,,since I drive about 30,000 miles a year..I wanted to limit plug changes

Very True! Iwould also add Bosch and Autolite to the list!

 

Yup. You are 100% right on.
