ITEM # : E3.70
Automotive plug that fits Ford Triton engine applications.




E3.70 is a 16mm, 0.860” reach plug with a taper seat. It fits Ford Triton applications from 2004 to 2008. E3.70 is a unique design that solves a problem with original OE application. The shell is made as a single piece, as opposed to two pieces, so it resists seizing in the engine and breaking apart when being removed. It is widely stocked in automotive retail stores. E3 automotive plugs have three legs securing the DiamondFIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles.

E3 spark plugs
I've been using these plugs in the older and newer style 5.4l engines at my work place. These plugs have been very successful in these engines. These engines do exhibit some quirks from rough idle to random misfires. These spark plugs are better than others I've used. I've found that these plugs are less prone to fouling out too. I've started using them in some of my customers other cars and trucks without problem. These plugs won't last as long as other plugs out there , but for engines that burn a little coolant or oil they seem to work great. The plugs are not overpriced and my local Advanced Auto Parts Stores have these plugs in stock all the time.
more power, reduced emissions, improved fuel efficiency, longer life, faster starts
