"I just installed these on my car and noticed an immediate difference. I haven't had them in long enough to see if there is a change in my mpg, but I definitely notice an improvement in acceleration and power."

Pros: E3 spark plugs
Cons: e3 spark plugs
"Before installing these plugs, dissconnect the negative battery for at least 45 minutes. Once these plugs (and/or K&N or similiar air filiter) are installed, then reconnect the negative battery. Now, when you restart the car drive it immediately at slow speed for a minute or two and then on the highway so the computer learns the new inputs from all the sensors. It will make a big deal on how the car runs afterwards. Do this every time you make any major modifications."

E3 Spark Plugs,
February 26, 2009
By Erik556
from Cassville, Mo
|
Pros: Vehicle Starts Quicker, More Power, Quicker Respones
Cons: No Increase In MPG
"I installed these spark plugs in a '03 Chevy S-10 in combination With MPG/PLUS gas saving ignition wire set, everything stated about the two was true except getting better MPG, but a V6 engine won't get the best MPG either."

Pros: slight increase in performance from old stock plugs
Cons: doesn't pay for itself for a while
"good upgrade, really gives you the peace of mind knowing your vehicle has premium parts installed that will perform. i recommend to upgrade the ignition wire set also to get all the performance you can out of these plugs."

Understated title,
October 30, 2008

Pros: I feel the difference in the power and the engine is much smoother. It appears that I'm getting better MPG.
"I like the idea and the performance is much like the touted Firestorm plug that is or was being developed. I think this plug will put that plug out of business. It has smoothed out my engine and I can feel the extra power. I'm looking forward to determining what my new MPG really is. I had been getting about 17 MPG and I believe I'm going to get over 20 now."

1999 Tiburon, 165k,
September 7, 2008

"I now have 6200 miles on these and have had no problems with them. I have a 104 mile round trip commute 5 days per week, 60 miles winding 2 lane and 40 miles hwy. I didn't expect much in the fuel economy department and wasn't disappointed. Vehicle already averages 33mpg and no change there. I have noticed more power in the 1200 to 2500 rpm range. There are a couple of hills on my commute where I previously needed to turn the A/C off or shift down to 4th but I can now maintain my speed without doing either.
I have yet to install them in my V-10 Dodge pickup but expect better results there."

Cons: price with buying 16 plugs
"I have a 2004 RAM 1500 Quad cab with a 5.7L Hemi and 60k miles. Other than the price with needing 16 plugs, I have notice a slight increase in gas mileage. It also seems to be more responsive. I've only had the plugs in for a few hundrend miles, so far so good!"

Pros: Improved mileage, power
Cons: Hesitation, misfire, backfire
"I put these plugs in my 2000 Jeep Cherokee 4.0L (New engine 15,000 miles ago) and was very happy as MPG went from 15 - 19 to 17 - 24+. However after a couple of weeks, the engine would stall on a cold start, sputter, misfire and hesitate. Have not ruled out all issues but the plugs remain a big one.
I also put these into a 2005 Toyota Corolla S and got similar improvements in economy but none of the negatives.
These plugs seem to be very picky with some engines. I still get the improvements on the Jeep however the running problems will probablly cause me to switch back to factory plugs."
