Rated 5 out of 5 by P1PV Great plugs
Great looking spark plugs, appear to be one piece bodies unlike OEM three piece plugs. Preforming great so far with about 500 miles on them. Feels good to have the power back and about half the price of the OEM plugs.

Rated 5 out of 5 by slammy Good plug, increased power
Changed all 6 volvo plugs on a 2004 XC-90 T6 with this plug. Pre-gapped, normal plug install. Noticed a little bit more pep than it used to have.

Rated 5 out of 5 by SinisterStang Best spark plugs on the market
Bought a set of spark plugs for my Dodge Ram, and what a difference, it put life back into my engine and have it even more horse power then when I first bought the truck. I don't know why any one would buy any other brand.Had a big difference in the gas mileage as well. Bought a set for my Mustang as well, and wow its like a new car! Recommend for everyone to switch to E3's!

Rated 5 out of 5 by Radman A great sparkplug at a great price
The spark plug is probably the best plug at its price on the market for this engine, most other plugs are five dollars per plug more expensive and they don't last as long. My truck runs perfect with 163,000 miles on it, no hesitation At all. It no longer bogs down going up hills.my last set of plugs lasted about 45 to 55,000 miles and the plugs cost more than what I paid for these plugs. The only problem I had was that ford did not make a engine that is friendly to do it yourself mechanics. It's next to impossible to replaced them in under one hour.

Rated 5 out of 5 by Goodplug E-3 Spark Plugs
I us them in a 2005 F150 with a 5.4 engine and they work great. Looks like you can get about 75,000 miles on them before you need to replace them. I think they are the best plug on the market for 5.4 ford engines.
Try them I think you will like them>>>Jim

Rated 2 out of 5 by sahmwong Should have listened
The service tech told me Volkswagens were picky about the plugs and that I should use the ones he specified. I used the E3 and now the cars sputters when it starts. Runs ok, once started, but I will end up changing them out.

Rated 5 out of 5 by DIYer Great plugs - great price
I installed these plugs on my 2005 CTS at 150,000 miles - Wow! Runs great!
Pre-gapped - no worries. Well built.
Compared to some other premium plugs these are sturdy, and reasonably priced.

No more ping when you step on the gas. Added horse power.

Rated 4 out of 5 by MYMKLT Noticable change at start up, power, and acceration
I replaced the reliable factory spark plugs in my 2007 Lincoln MK LT at around 60k miles with the E3 Premium spark plugs. I managed to remove all 8 plugs without breaking any off in the well...lucky me, I heard and read the dreaded stories. So, I choose this plug because of the construction of the plug. Although the new E3 plug size was 5/8 vice 9/16, I had no trouble installing or torqueing the plugs to recommended specifications. So far the seem to be working fine. I noticed a smoother Idle and boost in power since the install. Its has only been a week so I'm still evaluating mileage and fuel economy. So far So good. the reason for the 4 star rating in ease of installation/use is because of having to change my plug socket due to the size difference (though it does add strength to the plug...a plus), and I would like to take the time to test drive my truck for a while. I will post an update after a few thousand miles.

Rated 5 out of 5 by WeekendMec Improved performace
After installing in my 2004 Sebring, I noticed a 7% increase in gas mileage and a definite increase in power and acceleration. Just recently installed a set in my Daughters Audi and it has never run as smooth as it does now.

Rated 5 out of 5 by J10JEEPMAN smart choice for power
I put these spark plugs in my '78 Jeep J10 pickup truck . The engine has only around 4k miles on a rebuild . A very noticeable difference in the idling and the acceleration over the Bosch Platinums' I took out .
If a smooth running engine is your desire , the few extra dollars are for these plugs are a must .

Rated 4 out of 5 by GuitarGod Good and Bad
Installed these in a 2001 Jeep Cherokee Sport and noticed improved throttle response and power. 50000 miles later still running great. Installed a set in a 2006 Chevy Trail Blazer got maybe 15000 miles and they started fouling out and had to replace them with a set of autolites. I guess it depends on the vehicle if they work or not.

Rated 5 out of 5 by Jmelford E3 plugs are the best
I have purchased these for several vehicles. I get improved power and milage. I don't recommend them for the vehicles that require platinum plugs. I installed them in my Daughters Nisson sentra without telling her and after she drove it she wanted to know if I had done something to her car because she now had lots of power.

The welds on the electrode guard were uneven, they didn't fit correctly in the cylinder head. They went in the trash. I will never shop PEP BOYS again.

Rated 1 out of 5 by smarks Wrong size
the plugs coming out of a 5.4l 3v Ford triton engine are 9/16 these are 5/8. there is little enough room for the correct size socket without having to go bigger.
