" Okay, first - this is an HONEST review. I'm not a shill or anything.
My Volvo 850 has a long history of misfiring and fouling plugs, no matter the plugs I use (including Volvo original). Everything else has been tested and everything kept coming down to spark plugs - I'd replace a set, and have no problems for 10-15,000 miles. So I tried TONS of plugs. Moving to a colder plug helped a great deal, and I ran NGK-Rs for a few years.
Well, I went to replace the plugs while I was on vacation because they started to act up - as usual - but OReilly's didn't have them, so I got the E3s on an impulse buy since everything else failed. Installed them, all seemed normal, forgot about them entirely (I had a vacation to enjoy!).
So, for the last 50,000 miles, and two and a half years, I haven't replaced spark plugs - and haven't had any problems. I thought I was running the NGK-Rs and went to order some more, but couldn't remember the darn model, so I pulled a plug to check it out - BAM! E3.48... huh? How? OH! Oh, wow... I guess they worked, LOL!
That was basically a blind test! I've run these, as I said, for 50,000 miles (same (silicone) wires, cap, & rotor the whole time)... with nary a hitch. I drove them across the country four or five times (and back), in all manner of conditions. I sure thought those colder NGKs were finally doing the trick, LOL!
Yup, I'm buying more. Hope the next set runs as well as this set (I'm going to keep these old ones on hand - they're still in great shape).
Also, an important note, the gap is quite large and can't be adjusted and I run an MSD blaster2 coil, if your ignition system is weak and the gap isn't right, or your computer is overly picky, these may be a horrible fit for you.
The stock gap for my car is 0.028, and I think these are around 0.04... so quite a significant difference (but that gap may be the secret as to why they work so well for me...).
Also, aside from running well, I've seen no improvements in power or fuel economy. But, most importantly, they haven't hurt anything and they have done what no other plug has ever done - they worked! "

" have been using these plugs for years in all of my non-overhead cammed engine, they just dont seem to agree with the overhead engines but are excellent in anything else. always have saw slight fuel milage gains and noticable throttle responce. i do think that its odd that the plugs are different prices on this site for different part numbers, whereas on other sights, every plug is the exact same price ($5.99) "
