Video Transcript

John Trousdale:
Champion Spark Plugs is the name we all grew up with. I’m here with Rich Keller. Rich, the Champion has led the way for a long time but technology is changing. What are you guys doing to keep up and to lead the way?

Richard Keller:
We’ve had to change a lot of things over the years. One in particular, the life expectancy has gone up dramatically from as little as – say 15,000 miles now to over a 120,000 miles. Also, the voltage requirements have gone from as little as say 15 kV, now easily pushing 45 kV.

These things have forced us to make a lot of changes to extend the life. In addition, precious metals have now become the norm as oppose to just solid nickel electrodes.

John:
Tell me how technology plays a role in keeping up with the changing world of racing.

Richard:
With racing, we have to make sure that the firing-end is perfect. It’s well put together. The edges are nice and clean. There’s nothing, excessively – no burst. You want it sharp but no burst and the coverage is just right.

John:
You mentioned precious metals. Now I know you guys pioneer the Iridium movement. Tell me more about that.

Richard:
Iridium is actually originally used in the aviation industry for turbine jet engines. And then it went into the industrial market shortly thereafter. This goes back to the 1960s.

John:
What’s the key to racing plugs?

Richard:
The racing plugs have to be really well-constructed. They have to have a very strong shell seal. They have to have a very strong ceramic. The life expectancy is still fairly short but that expectation still is quite high that the product holds together for the entire run.

John:
Now Champion does a lot to support Grassroots Racers. Tell me more about that.

Richard:
Champion has a new program in 2012. We’re sponsoring Grassroots Racers. If you go to alwaysachampion.com, you’ll see all the details on it. But essentially we’re giving away a hundred thousand dollars in sponsorship, five $10,000 sponsorships as well as one grand prize of $50,000.

John:
That is big news. Racers out there listen up, alwaysachampion.com is where you can enter to claim up to a hundred grand in sponsorship money from Champion. Rich, thanks for having us. Power TV at PRI.

Champion Spark Plugs
by Michael from Willis, Texas on October 11, 2017
These spark plugs are the exact factory replacement plugs for my Evinrude 200HO ETec. On this particular motor, the plugs have to be indexed to the injector so the open part of the plug is positioned within 90 degrees of the injector nozzle. If that is not done, the spark plugs will pre maturely foul and other idling problems will occur. Many mechanics will say you can cross reference these plugs but, with these plugs I have confidence that the job will be done correctly. I'm a big believer in using the exact factory replacement plugs. Champion makes a great plug and I won't use anything else.

by Robert from Lake Cowichan, British Columbia on January 28, 2016
These plugs are what is requires for evinrude FICHT. They must be indexed (so ensure to buy a few extra), fortunately these are a great deal, price is for a box of four.

Uncle Gadget
by Gerald from Perrysbirg, Ohio on August 22, 2012
These plugs are difficult to find. I have a new two stroke motor that these plugs will be used in when the originals wear out.

Q:
Replacement spark plugs must be indexed correctly. What dose that mean?
A:
Indexing a spark plug in a cylinder head is the process of aligning the ground electrode on the spark plug to a specified direction inside the combustion chamber.


Q:
Is that per box and if so how many per box?
A:
Comes with 4 in a box.
