Spark-plug maker Johnson Matthey is a breath of fresh air for all of us

"We're positioned in markets where we think there's structural growth driven by the environment and environmental legislation," says Carson.

That approach has delivered a £5 bn market value and profits at its last year-end of £260 m, an increase of 14 pc.

"In a flat car market for example, we would still get growth because in various regions around the world the legislation is saying 'we have to have cleaner cars'. We have a third of the world market. We're a very science-based business and we are striving to make a better catalyst, a smaller catalyst that will save people money and make money for us."

But precious metals remain at the heart of the business. "That's the place to start. The thread that runs through all our divisions is precious metals. Spinning out of that have come the environmental technologies and fine chemicals divisions."

One crucial fact to know about Johnson Matthey's precious metals divisions, and why it has such a strong position in catalytic converters, is that it has the sole marketing agency deal with the world's leading platinum miner – AngloAmerican Platinum.

E3 Spark Plugs Monster Truck Nationals roar into town

SUNDAY, SUNDAY, SUNDAY ... er, today and Saturday. The chorus of engines rumbling, the crunch of steel on steel and the odor of burning rubber will fill the Bryce Jordan Center this weekend. The only questions is: Are you ready for some monster madness? Monster truck madness, that is.

On March 30-31, the arena will be home to the E3 Spark Plugs Monster Truck Nationals presented by Lucas Oil.

Emily Boden, from The Promotion Company/Family Events, promised a good time for all who attend.

“At this event, you will see some ground-pounding, car-crushing action that is bound to get your attention,” she said. “You will see six monster trucks compete in the doughnut, wheelie, drag racing and freestyle competitions which the fans will be able to vote for the winner.”

Fans will judge all events except the drag racing contest.

Boden added, “Plus you will be able to see the world’s youngest monster truck drivers featuring Kid KJ in Monster Bear, Jake in Sir Crush A Lot and Cassie in Demolition Diva. You will also witness Transaurus munching on a car and breathing fire.”

Difference between IRIDIUM spark plugs for cars vs boats?

Is there a difference in car and boat spark plugs? I was looking at Iridium plugs and for my truck 8 are $50, Same 8 plugs for sale at a boat supply store is $10. It even has the same Delco part #41985...


As long as they are of the same part number, there is no problem.

After how many miles should u change your spark plugs? Iridium plugs last 100k miles?

I often get different answers as to how many miles your spark plugs are good for. I keep hearing that the iridium plugs last 100k miles but this seems a lil hard to believe, how true is that claim?


are they gaped properly thats all you need to know


40,000 to 50,000 miles. Before you buy Iridium plugs ask for the 100,000 mile warranty.


It depends on the motor and im not sure about iridium plugs but Platinum plugs have been around for years....I have a 1999 suburban that came with Platinum plugs, GM recommends replacing them at 100k........I have 151,000 on them....no misfires, but they probably dont look too pretty : )


The plugs will be fine the problem we find is a lot of the time the spark plug wont come out. I suggest to replace at 60k just for that reason, and have anti-seize on the threads and then dielectric grease to the spark plug boot to keep moisture and water out, also ads to boot removal next time.

will the iridium spark plugs make so much difference?

iridium spark plugs from Denso or NGK will they really worth the money?


yes in most cases,and no in others,it all depends on the engine their going in ,one plug that i know always makes a good difference is the Bosch platinum ,it helps any engine you put it in,the iridium plugs cost too much,and you cant tell the difference in them and the Bosch platinum plugs,except for the price,id just use a good Bosch plug in it,they last well beyond 50 thousand miles,and that's a lot of driving,and you,ll get your moneys worth from them also,good luck with it.


YES AND NO....................


IT WOULD DEPEND WHAT YOU ARE PUTTING THEM INTO.

I want to know, how can you tell when it is time to replace the new Iridium spark plugs?

I have a 2004 Dodge stratus R/T, basically a mitsubishi eclipse. I have never been exposed to these spark plugs,
I am a mechanic I am trying to find out if there is some indication on the electrode itself that show it is worn out


Check the owner's manual for the vehicle in the maintenance section to be sure, but most iridium spark plugs have a 100,000 mile service interval. Do not confuse iridium plugs with platinum ones...platinum plugs do not resist carbon build-up as well and will need to be changed more often. As for the dual and quad tipped plugs by Bosch...these are platinum and only have a tiny amount on the ground electrodes...none on the firing electrode.

The best choice for this engine would be NGK or Denso iridium plugs...usually around $10 each from the aftermarket parts stores.

Generally,does iridium spark plugs worth the money?

Planning to fit a set of Denso iridium and want to know if they really worth.


Kind of depends on the vehicle they are going in. I've got a set in a high performance 4 cylinder and I love them. It's one of those things you do if you're trying to get every ounce of use-able horsepower out of your vehicle.
