Saving Gas! What did you Do?
I replaced my spark plugs with E3's and wow what a difference. Even tho my Motorhome has only 53,000 on it. It runs so smooth now and I can see the change in gas mileage. What a difference. Spark plug...

In a test I read a few years ago these so called designer plugs do work (slightly more power) in testing when new. But after a thousand miles on a retest they did not show any improvement in power and or possible MPG improvement. They do some how wear enough that after a 1000 miles on the designer plug, they could not find a measurable difference between a 1000 miles on a regular new plug and these designer plugs.
In the test they tested several including spiltfire and and I think or pretty sure the E3 was there also.
The article did convince me and imply that it was a waste of money to pay more for the designer plugs for my vehicle usage. This article and testing was done buy Hot Rod or Car Craft magazine?
