From Shreveport, LA
Ordered online and picked up at store; fast and convenient. Installed in 2009 CR-V torqued to 13 lb ft. These are the retail 4 pack version. Made in Japan and not assembled in US with foreign parts. Denso makes non-retail version of the IK20L (5358); it is the middle plug; it has no color rings and dull colored terminal; it does not come in 4 pack but sold individually. The first plug is the original factory SKJ20DR-M11 (3377). I could not find the "non" retail version middle plug on Denso's product site which concerns me. I prefer the retail version at least I know they are not fakes.

I wanted a Delco Iridium but was unavailable for this application, (Jeep V-6). These plugs worked fine but I have used the Delco's previously and prefer them.

E3 - DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No. E3.74)
DescriptionThe 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. E3.74 is a 14mm, 1.000 reach plug with a taper seat. It fits a wide variety of late model applications, especially Ford applications. The automotive plugs have three 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 during each combustion cycle.
- 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.

Installed a full set in my 2016 Silverado with a 4.3. Shortly thereafter, engine started sputtering on takeoff to full misfire on heavy acceleration. Replaced with ACDelco plugs, no problems. I have no clue what the problem is, my 6.2 Camaro loves them🤷🏻♂️
