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 Erik556from 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."

Understated title,
October 30, 2008
By george2from McDonough, GA
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."

"I hoping for a slight increase in fuel mileage in 05' Gmc Envoy Denali, but I didn't see anything noticable at all. I did notice that the vehicle does start faster. All in all not a bad plug, just don't expect it to be a fuel saver."

1999 Tiburon, 165k,
September 7, 2008
By lostburrofrom Cave Junction, Or
"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 performance at a good price Cons: None
"Put 4 of these in a 2003 Dodge Neon. Very easy installation, no problems. Noticed that now it starts faster (1-2 turns) than before (3-5 turns), seems to have more power at take-off and up-hill, and the fuel efficiency went up about 5% or so even with the AC on. I will put these in all my vehicles and try to convert my friends over also."

Pros: I must say that I am really happy with increased performance & fuel economy on my 06 Chevy Silverado with 4.3 liter! Cons: none
"I just would like to say that based on the factory installed AC plugs on my 2006 Chevy Silverado with a 4.3 liter I have seen a marked increase in performance and fuel economy both in town and on the highway. I have always been a big fan of any AC product but these E3's are the best and everybody should get them and see the difference. I also put one in my mower."

"I just installed these in my 92 Jeep Cherokee and tell the advantages right away. I can feel the power increase and my engine is running very smooth. I would recommend these plugs to anyone looking to buy some high quality plugs. I haven't had them in long enough to see if it helps my fuel mileage but I will be happy even if they don't."

Pros: Improved gas mileage and power Cons: Changing spark plugs on some vehicles may be difficult.
"I installed these plugs in my 91 F150 about a year ago. It started smoking for the first five or so miles, I assume the plugs were cleaning the combustion chambers. After that stopped, there was a noticeable increase in power and gained about three miles per gallon. Cold weather starting (-20 to -30 degrees)became easier too. I will be purchasing two more sets for my other vehicles as well."

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."

"I put these plugs in my 89 toyota 4x4. I have only run one tank of gas through since the install and I did not see a gas mileage increase but there is a noticeable difference in throttle response along with immediate engine start up. With regular plugs this pick-up would crank once or twice before starting. Now it is like a brand new pick-up. One little turn of the key and vrooom. I am going to purchase another set of four for my 2000 Dodge Stratus. If they perform as well in there my wifes vehicle could be the next recipient of the e3 plugs."

Pros: Better gas milege, smoother throttle response. Cons: Cost. The weird looks people give you when you rave about spark plugs.
"Installed these in my '98 Saturn SL with 202400 miles. I was getting 38-42 MPG now I'm up to 40-44 MPG. Car runs smoother and better throttle response. Have 8000 miles on the plugs now and they look new."

"I put them in my 2001 Dodge Intrepid. I was expecting a fuel mileage increase but didn't see any. Felt a slight power increase but I expected that from any new plug at first. Maybe I expected too much from all of the possitive reviews I read before I chose to purchase them."
