E3 automotive spark plugs are SOLD EACH they utilize the latest E3 technologies to help engines operate more efficiently by burning fuel more completely. Our patented design gets the flame (or combustion process) started earlier in the combustion chamber before gas is vented off when the exhaust valves open. Although results may vary dramatically based upon piston displacement and operating conditions, increased combustion efficiency and a faster burn allow E3 equipped engines to minimize the venting of unburned (wasted) fuel.
Good thing about a lot of the "older" Jeep models is that they used the same plug. E3.58 helps to provide more power and better fuel efficiency due to the more complete burn of the fuel during each combustion cycle. Another benefit is the smoother idle and acceleration from the efficiency of the burn.

E3 Spark Plugs E3.70 Ford Automotive Spa
The 2004-2008 OE spark plug for the Ford 3-valve engine has a tendency to "split apart" when being removed during a tune up. E3 Spark Plugs developed E3.70 as a single piece design for these applications, which eliminated the challenges of the OE two-piece design. In addition, this part number has all of the other consumer benefits of more power and better fuel efficiency of E3's DiamondFire technology. The unique side wire configuration of the E3 plug promotes the fastest and ultimately largest flame front, which more completely converts the available fuel to energy with less left over fuel venting at the end of the combustion cycle. The consumer benefits by having more of the fuel put to work with less waste, provides more power during each combustion cycle with better fuel efficiency.

Stay away, right after install misfire developed and pulled them out found ceramic broke in 3 plugs and slid down to smother spark, do yourself a favor and dont buy.

Installed these in my high mileage 4.0L I-6 2000 Jeep Cherokee motor. I had a really bad miss at high RPM and was trying to find the problem. Changed the plugs with these and instally the idle was smoother and the miss is gone. My old plugs were in pretty bad shape. I am extremely pleased and it looks like I even have gained a MPG or so.
Will this product work on a 1995 Jeep Cherokee Sport, 4.OL

E3 is known as a spark plug company, but they started out is as a research and development company. Anybody could produce a spark plug because the design had basically stayed static since Henry Ford's Model T. The founders of E3 partnered with the engineering departments at two leading technology universities and invested a lot of money and time in creating a completely renovated spark plug design. The J-wire electrode was replaced by E3 with the patented DiamondFire ground electrode, the basis of E3's superior spark plug performance. With increased burn control E3 spark plugs can offer Jeeps increase power output, fuel efficiency and reduced emissions. Shop E3 Spark Plugs Now
