All talk and no walk..... Posted 2007-11-10 14:01:19 by ryan77

This spark plug is no different. The features are so small like the horsepower gain and the amount you'd save at the pump, it's more a mental thing because you read this hype and think it's going to make a difference and the only change you get is what's left over after paying such a large amount for a plug thats no different than the rest, that's only my opinion. Stick to Champion or NGK. Thanks.

I installed e3 plugs in my 2000 gmc sierra and noticed a slight difference in power but noticed a little over a 1mpg increase when I drive normal. Thought they were a little expensive but they did make a difference. much better then the bosh platinum 4s.

Hmmm, yeah, where's those extra ponies? Posted 2007-12-17 00:45:05 by cpear760

I installed a set on my 95 S10 Blazer. I haven't seen any improvement in mileage or horsepower. I'm not sure who has the magic spark plug yet.

e3 plugs Posted 2007-12-17 11:34:47 by srinde

install like any other spark plug. one out of set of six was no good. noticed a miss right away, found out which one was bad and replaced it with one of my previous plugs. maybe noticed a somewhat smoother idle but my fuel mileage actually dropped noticeably. i drive this vehicle 150 miles every night for my job and fuel savings was the main selling point to me even 1% difference would be nice. have sent a couple of e-mails asking for one replacement plug to give them a try as a full set before i give them up but no word back yet. my vehicle is a 88 jeep cherokee with a 4.0L. may be possible that on a newer, more advanced engine there may be some improvement.

"PIECE OF SH*T" Posted 2007-12-25 17:34:47 by chevyman91

I put these on my '97 dodge ram 1500. They have been on there for about 4 months and i drive this truck about 60 miles every day and still i have yet to see an increase in gas milage, but i did notice a very fraction of increase in hp and tq. I am even runnin a hypertec power programmer, msd plug wires and a k&n air filter and with all of them im still gettin the same mileage. My opinion is to just buy some champion plgs if you are thinkin bout replacing your old ones with these because they suck ass.

Posted 2008-05-12 15:26:23 by Powermaniac

I have installed these in two different vehicles in last two years. One a 98 Ford F150 V-8 4WD went from 15mpg to 18mpg. 2005 Dodge Ram Hemi Quad went from 16mpg to 19mpg. THEY INCREASE FUEL ECONOMY PERIOD. However, unlike some of you I have no dyno in my garage so I can't say on horsepower. I drive the Dodge as my daily driver. It FEELS like it has more torque. Just added a cold air induction system from K&N verdict is still out on that. Face it! It's a NEW TECHNOLOGY, eveyone else is selling you a platinum or iridium plug with old engineering. Has anyone checked iridium or platinum prices? It's platinum and iridium plug all right. SUCKER! At least these give better mileage.Look at the warranty

They REALLY Work Posted 2008-05-20 21:57:19 by 4WDLUVR

I read with skepticism all the hype and thought it was another gimic. Put Bosch in my Ford Truck and check engine light came on. Dealer said all plugs but original type cause this problem.I decided to try anyhow. NO check engine light on and picked up 2 miles per gallon. It feels like it is smoother accelerating and has more power. Inexpensive compared to Platinum and Iridium. So far so good.

E-3 spark Plugs Posted 2008-05-27 11:29:14 by mountainwest

The spark plugs were easy to install along with the new plug wires. They seem to make my 3500 silverado 8.1L run smoother and gave me more hp. I noticed a 2 mpg increase. Well worth the purchase

great plugs! Posted 2008-06-10 20:10:40 by diannesplace2003

I tried these plugs in my Ram 1500 and was so impressed (my wife says I am the worst skeptic) that I bought some for my wifes Tacoma. They really did help with gas mileage( about 3+ mpg) and especially for my Ram, every little bit helps!! Highly recommended!!

great plug! Posted 2008-07-14 01:51:38 by craig sheley

I put these plugs in a 96 silverado 5.7 and noticed a smoother idle right off. I don't have a dyno sitting in my garage like some of the people who have reviewed this product, but there is a noticable throttle response increase and I got just over 2 mpgs.

My truck was due a fresh set of plugs could have spent less for other brands but liked the idea a no gap firing-makes sense-old 79 chevy truck runs smoother feels like better gas milage is in the mix too. Keep on kruzin

E-3 Plugs Posted 2009-03-18 17:10:49 by EaglesN3st

(2002 Chevy S10 4x4 Crew cab V6 4.3L) Idles great, some added power/acceleration, but fuel efficiency has improved dramatically even with the oversized tires. Also purchased the MPG Plus plug wires. No complaints.

great plug Posted 2010-03-28 02:39:01 by truckfan78

I installed these plugs on my 2007 Dodge Dakota with the 3.7 and with the stock NGKs got 12 mpg with nothing in the bed, after I put these in, got 14 with 200 pounds in the bed. I also have coil on plug so Im not sure if that helps any. I can tell it added more power too. burning rubber on moderate open throttle. well worth the money

Truck idles smoother and runs better. I installed these after I had already installed a AEM Brute Force cold air intake and a AirRaid TB spacer and also a Gibson cat back. I drive an '06 Tacoma 4.0L and now it runs awsome. Hits the speed limiter in no time

Best plug ever Posted 2010-09-12 01:34:09 by Anonymous

Installed these spark plugs first in my 1999 Grand Am GT before getting these my car was getting about 24 mpg after installing I got an amazing 26 mpg city driving. Amazing for a 99 140,000 mile car. I've also installed these in my fathers Hyundai Tiburon faster off the line. So more power better mileage well worth the money. I will be putting these into my 93 suburban. great
