Product Description

About the V-Power.

Modern lean-burning, fuel efficient engines create a new set of requirements for spark plugs. NGK Spark Plugs answered the call for a spark plug with lower sparking voltage requirements by developing the V-Power, the only spark plug with a v-groove electrode on the market today. Why is this important? The v-groove center electrode on a V-Power spark plug forces the spark to the outer edge of the ground electrode, placing it closer to the air/fuel mixture. What this does is allow the spark to more quickly ignite the mixture, providing more complete combustion.

More complete combustion not only provides more power, it also means less harmful emissions. These emissions are not only damaging to the environment, they can reduce the life of expensive catalytic converters and oxygen sensors. V-Power Spark Plugs also require lower ignition firing voltage, resulting in quicker starts and easier cold weather starts throughout the life of the plugs.

Here are some of the features of this plug:

  • Triple-Gasket Sealing Process
    Virtually eliminates the possibility of combustion gas leakage through the shell. Most other manufacturers only use two seals.
  • Solid-Copper Core
    Produces a more powerful spark with less firing voltage. Other manufacturers use a copper coated center core.
  • V-Groove
    Forces the spark to the outer edge of the ground electrode, placing it closer to the air/fuel mixture. This allows the spark to more quickly ignite the mixture, providing more complete combustion.
  • Cold-Rolled Threads
    For easier removal and installation.
  • Corrosion Resistant
    Zinc Chromate Coating Double-dipped for maximum protection. An NGK exclusive.
  • Alumina Silicate Insulator
    Is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance.
  • Corrugated Ribs
    Eliminate flashover, which can cause misfiring and engine damage, especially in damp environments.

About the Iridium IX.

It may be time to invest in precious metal futures. NGK Iridium Spark Plugs represent the ultimate evolution of spark plug technology and performance. Iridium allows for a center electrode 75 percent the size of a platinum electrode and 24 percent the size of a conventional nickel electrode.

The fine electrode tip is engineered for greater ignitability. And it's in the design of the iridium tip that makes Iridium IX a better spark plug. The electrode is not too thin and not too thick. It's just the right size to reduce the voltage required for spark and to maximize the overall longer life qualities of iridium.The result are spark plugs that require less voltage to spark, burns fuel more efficiently, sparks at leaner air/fuel mixtures, and delivers higher horsepower and better gas mileage. NGK's new Iridium IX is the personification of these qualities and takes premium performance spark plugs to a new level. A level that is expected from the world leader in spark plugs.

There are two advantages of the TR-55IX. Longevity and gapping. According to NGK, the Iridium IX should last longer than the V-Power Tr-55 and you'll also be able to open the gap up for better performance. We recommend leaving the Iridium IX plugs gapped at .060 as a baseline for your modified engine and tuning from there for your specific car. Be extremely careful when gapping the plugs due to the Iridium center electrode.

Please check your application carefully before purchasing these spark plugs - they may not be applicable to your vehicle as they are more of a generic type of product.

NOTE: 2006 Impala & Monte Carlo: TR55/IX Compatible with 5.3L V8 only. Not compatible with 3.5L or 3.9L V6

i also have Msd packs and Pjr or prj wires and the combo is as smooth as silk. Just be ready to gap the 55ix's.
Great Plugs

I have MSD coil packs, PRJ 10.4 wires, and TR55Ix Plugs. Great combo...Trust me!
Great Addition

I added the MSD coils, MSD wires and NGK plugs to my 2004 GTP CompG, and wow what a difference. Besides looking nice under the hood, the power was noticeable as well. I recommend this to anyone who is looking to not only gain a little more power, but also if your looking to clean up the engine bay.
Great plugs
Michael S (st paul, MN US) | February 27th, 2008
These plugs are great and work even better with the coil packs from MSD and MSD wires. HUGE difference, love em, will use again.

Without a doubt one of the best plugs on the market. An absolute must when modding. Just have to remember to use a colder plug when greatly increasing HP.

Really nice plugs. Want more spark buy these they deliver alot more spark which produces more HP, which I love.
