## Description

Denso (5358) IK20L Iridium Power Spark Plug, (Pack of 1)

Review: Performance above OEM - Cross shopped these with the Denso Iridium Long-life (SKJ20DR-M11) and NGK Laser Iridium (1ZFR6K11) spark plugs for a 2004 Honda CR-V. The differences were subtle, but quantifiable. The Denso Iridium Power spark plug (this IK20L) is designed to improve performance and features the smallest diameter center electrode (0.4mm). The other designs emphasize long life and OEM style and fit, not necessarily increased performance over OEM. When I pulled the stock NGK Iridium spark plugs (at 105K miles), they looked pretty good considering the time and mileage on them. With these Denso Iridium Power plugs installed, the Honda runs more smoothly but, truth be known, with no discernible increase in actual performance. That's fine, since they are all about the same price anyway. And I like that there is at least the potential for improved performance. Bottom line: I'm happy and so is the Honda.
Review: Buena y económica - Exelente de muy buena calidad

### ⭐⭐⭐ Suspicious Denso Labeling & Poor Packaging
*by V***P on November 1, 2021*

Very disappointed. The advertised picture shows an original Denso type plug with words including "Japan" engraved around the metal collar of the plug along with blue painted lines to indicate Japanese origin. These plugs have "Assembled in the US with Foreign Parts" engraved around them with no blue lines which could mean made in Russia, China, India, or ???. The plugs were packaged poorly; just a brown envelope to where the plugs were falling out of their boxes and poured out in one big mess. I gave three stars for the expedient delivery and no broken plugs. I've read too many stories about possible counterfeit plugs, so I returned them. Still trying to figure out how to get official "Made in Japan" plugs for quality assurance sake, but realize counterfeiters can put those markings on them as well :(
