Product Information

Product Details
Part No. E3.82
Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)
The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.82 is a 12mm, 1.000 reach plug with a gasket seat. It fits a wide variety of late model applications, especially import. E3.82 has two legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.

Product Features:
  • E3's Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn
  • Smoother Acceleration & Idle - The faster flame initiated by the The spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
  • Energy - Power output improved up to 6% on average in the typical operating ranges. Results will vary.
  • Efficiency - The "diamond shaped" side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work durin
  • E3's patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
  • The Spark Plugs are pre-gapped at the factory and cannot be adjusted.
  • Patented Electrode Configuration: The unique patented electrode design of the E3.82 spark plugs increases combustion pressure, resulting in enhanced power output and improved fuel economy.
  • Superior Heat Transfer: The two legs securing the Diamond FIRE electrode to the shell ensure excellent heat transfer, promoting better engine performance and longevity.
  • Wide Compatibility: The E3.82 spark plug, with its 12mm, 1.000 reach and gasket seat, fits a wide variety of late model applications, especially import vehicles.
  • Enhanced Engine Efficiency: By creating more turbulence in the cylinder, the E3.82 spark plugs improve combustion efficiency, leading to better overall engine performance.

Most Liked Positive Review
Wow Whee!
I replaced the plugs in my 2001 PT Cruiser and darn near doubled my gas mileage. The engine immediately idled and ran smoother. The gas pedal is more responsive, and everything seems to run better, and cooler, believe it or not. I am quite impressed with these plugs. Although their a bit more pricey, the investment is worth every penny. I will never use any other type of spark plug, I'm sold!
Most Liked Negative Review
GARBAGE! DO NOT BUY!
Bought these in September and by March with less than 3000 miles on them 2 were misfiring and 1 of those 2 was completely melted through. I mean torched not even just burned out, torched. I am lucky these plugs didn't cause any major damage to my engine, that I know of yet (knock on wood). Long story short I will never buy these again and will tell everyone I can not to buy this product or any E3 product. Thankfully Advance returned them as defective.

Does the E3 spark plugs fit a 1971 Chevelle SS LS5 454? ( with a carburetor) If so, which E3 series should I buy?

No Jerry, this E3 DiamondFIRE Automotive Spark Plug (Part # E3.40) does not fit your 1971 Chevrolet SS LS5 454. The exact spark plug for your vehicle is currently unavailable online. I would suggest that you visit the nearest Advance Auto Parts store to check the availability of this part.

However, I'd recommend that you contact them directly at 904.567.5994 and one of their Parts Pros will gladly assist you with this question.
is this the 3.3 or the 3.5 plug?
Verified Reply - John the Car-Doc
Hi David! Since you didn't mention the specific vehicle, it's hard to tell for sure. To check compatibility, I would need the year, make, and model along with the engine size of the vehicle.
