Have you ever seen a ‘late night’ commercial for an automotive product that was supposed to give you something for nothing? Maybe something you stuck in the air inlet to re-engineer the air flow, or something you stuck on the fuel line to realign the molecules? “Install this revolutionary product and improve performance and fuel economy.” That’s what I thought when I first saw the DirectHits system that was sent to us by Roadless Gear. But first impressions (evidently) aren’t always what they seem…

The Components

The DirectHits system includes a new set of Magstar Gold plug wires, solid ‘zero resistance’ center conductor plugs and a set of DirectHits spark amplifiers. For installation there is also a package of silicone dielectric grease and a plastic twelve point socket.

The plugs and wires are replaced just like normal. The plug gap stays the same as stock and so does the OE torque specs. But that’s where it ends. Remember the little cap that screws on to the end of a spark plug? Here is where you leave the cap off and screw on the DirectHits amplifier!

The Numbers

When you first drive the vehicle after the upgrade, it doesn’t seem like much of a difference, but when you start to gather the numbers it is evident that fuel economy and performance has improved. We tested the DirectHits system on three different engine configurations, including both carbureted and fuel injected models. We did this so that we could cover the most common powerplants Samurai owners are using today.  

Vehicle 1	Engine	Aspiration Method
1988.5 Samurai	1.3ltr	Carbureted
Vehicle 2
1991 Samurai	1.3ltr	Electronic Fuel Injection (EFI)
Vehicle 3
1992 Samurai	1.6ltr 8valve	Electronic Fuel Injection (EFI)

These are not new vehicles, they are well used vehicles that have seen their share of use and abuse so we didn’t bother with factory numbers. We assessed all three of these vehicles over a thirty day period to establish a baseline on fuel economy and acceleration on a flat, measured distance. We then installed the DirectHits system on each vehicle for a thirty day period to find an average that could be compared to the baseline numbers. This (we hoped) would show the level of improvement using the new components.

In Summary

The data shows that the installation of the DirectHits system did improve both fuel economy and power. The vehicles tested were not strictly factory stock (some upgraded more than others), so your mileage may vary. The DirectHits system does indeed do what they say and improve performance.
