The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. 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 the 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. The automotive plugs have three legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE ground electrode is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.

Product Features:

The design of the Ford Triton engine can a cause build of carbon on the spark Plug threads, which may make removal difficult. E3.70’s shell is made of a one-piece design, which means it WILL NOT break during removal.
E3’s Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn
Smoother Acceleration & Idle – The faster flame initiated by the The spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
Energy – Power output improved up to 6% on average in the typical operating ranges. Results will vary.
Efficiency – The “diamond shaped” side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work durin
E3’s patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
The Spark Plugs are pre-gapped at the factory and cannot be adjusted.
