Although plugs are a very important part of the engines high voltage electrical system, the only way you would gain something like 5 hp from replacement of the plugs is if the old plugs you replaced were destroyed.

For further information read the internet and see how after a few thousand miles these plugs fail like crazy and cause misfire under all driving conditions.

Also, does not apply to the original article writer, but if you replace your spark plugs with these and are still under warranty, and you develop a misfire, or other problem that might be related to these plugs, the manufacturer will not cover the repair if they see these plugs in the cylinder head. This I know for a fact.

i’ve put these in my 06 hemi ram and i havent had any problems out of them. i installed them about 3 or 4 months into the beginning of this year. i’ve read a lot about people having mixed reviews of them but they’ve worked perfectly fine for me. when i had them in, i immediately noticed an increase in acceleration and performance. it felt like i was driving the truck for the first time again, not being used to the power. now i get over 20 mpg consistently if i can keep my foot out of it haha

I put these plugs in my 98 Corvette.
The car initially ran great.
After about 500 miles the car started missing at idle and then when accelerating from anything below 1500 RPM.
I had to replace the plugs and the problem stopped.
Seems like a great idea, hope they figure out their manufacturing/quality control process.

Derrick – I am not sure of the manafacturer name. The ones I am talking about are basically minature plasma torches. The inventor as actually been able to run the engine on mists of water. Water in a fine mist will actually burn if it put under enough heat. These plugs are going to start at close to $100 a plug. So for a 4 cylinder I would look into them but not for my truck.

Oafman do you mean the Pulstar Pulse plugs, nothing like paying $25 per plug.

What in the holy fuck does the first post say? I’ve tried reading it twice and I think I’ve become slightly retarded because of that.

Guys make sure you check out the Horsepower TV video thats linked above. Click on the highlighted area that says “demonstrating a new spark plug”

my friend put some in his 1999 gmc sierra and you could tell a difference in it

This reminds me that it might be time for me to change out the plugs and wires on my Suburban. The quality of the plugs is very important to how the engine runs. The hotter and more consistant the spark the less fuel is needed and the more efficiently the fuel burns. At the low cost of these plugs it might be worth a try. BTW be on the lookout for a new plug coming out later this year. It is able to create a plasma spark which is many times hotter than the standard plug. This allows you to use a finer mist of gas thereby improving MPG by 50% to 100% depending on the size of the engine. I will have to get the name from my fuel savings expert here where I work because I forgot to write it down.
