I already did and I returned the Auotlite.

I had issues with the Autolite and they said I must replace my sparkplugs with 2 Double Plats and 2 Regular Plats from the factory.

They told me that's why the Autolites didn't work and gave me bad gas mileage. That I have to resinstall the OEM's with the two different part #'s

Issues:

I just put in the Autolite Platinum Pro/Extreme Perform. APP5364 today!

First issue: The reach on the plug was about 1/4 inch longer than the Motorcraft and I was concerned with that.
Also, the guy at the store said the gap should be 0.52 and the pugs were at set. BUT, at http://www.autolite.com, they say it should be at 0.50.

Second issue: I notice a *decrease* in gas mileage....it's aweful. I just came back from driving a distance I drive all the time and notice I used almost used a 1/4 tank of gas when I normally ony use about and 1/8.
