E-3 Spark Plugs

[jekehoe]

Has anybody tried E-3 Spark Plugs? Any difference?

I'm sorry to say that I watched their video... which really said nothing. At the end they want you to believe that the burn rate of a fuel changes based on the source of ignition (which is not true).

Just another take on the spark plug gimmick that's been going on for many decades.

The stock NGK iridium plugs are the best plugs you can buy. There is a reason the Honda engineers used them. They last for 100k miles and provide all the spark your truck will ever need. They can be had on Amazon for less than $10 each whereas a dealership will charge you about double that. Easy DIY job and you can save a few hundred bucks by doing it yourself. Don't use anti-seize on the threads and make sure you torque them to 13 lb./ft! Almost learned that the hard way.

multiple ground electrode spark plugs have been around as far back as I can remember. At my age that's waaaay back. The extra ground electrodes do nothing to improve spark.

Think of the spark as a miniature lightning bolt. As voltage increases there are many potential paths to ground. When the air ionizes and the spark occurs it goes to only one point. The other ground points remain inert.

The fact that this stuff has never went away proves that PT Barnum was right all along.

You would never see a difference on a Ridge, ......HOWEVER, I watched dyno runs on a 470HP small block chevy and after setting down a couple of base runs they replaced the plugs with E3s, it made almost 5HP more.

why switch? OEM plugs last over 130K miles. Iridium lasts longer than Platinum or copper.

German cars take german plugs, Japanese cars take japanese plugs, domestic cars use domestic plugs. Short term some different plugs may feel better or work better but long term they usually fail early.

Was that in person? I've always been skeptical of watching those sorts of things on TV shows or other videos. I'm sure E3 paid a lot of money for when "Horsepower" on Spike did a test running regular copper plugs in a high performance engine and then running the E3's - supposedly yielding an 8hp gain. Who's to say the copper plugs were gapped properly or were even the proper heat range? I'm sure there are instances where the E3's would probably outperform other plugs, but the RL is not one of them. The NGK iridium is an expensive plug for good reason. Any time you can get 100k+ miles from spark plugs, you're doing well. I changed mine at 108k miles and they still looked like they could go another 100k miles.

.....Agreed......and yes I was at the dyno session painfully watching as I am a die hard Ford man!

That could easily be attributed to the car cooling down between spark plug replacement. A 5hp difference really shouldn't be a measurement for any improvement on something of high horsepower

With no disrespect intended, dyno runs are done under identical conditions to ensure that the results are truly comparative. This means the same oil, oil pressure and temp,atmospheric conditions, A/F ratio and yes...engine and water temp.
When you're drag racing to within .001 seconds, 5 HP CAN make the difference between a win or loss and a LOT of $$$$$.
