Err But They Look Identical I Hear You Say?
Just when we thought the counterfeit NGK Spark Plugs we found recently were a pretty close match to the real thing, we’ve now found counterfeit Denso Iridium Power Spark Plugs as well. Every detail has been cloned to the closest result possible, except for one major flaw; these plugs don’t actually feature any Iridium in the center electrode at all!
- Alarm Bell 1: No laser-welded Iridium tip, features a machined down nickel alloy tip instead.
- Alarm Bell 2: Low-resolution, scanned copy of the box.
- Alarm bell 3: Major blooper – EAN of the 4pc outer plug box is stamped onto the 1pc inner boxes.
Below: The same EAN barcode for a 4 quantity plug box has been printed on all of the 1x plug boxes inside, which is completely wrong. Real Denso plugs use a different EAN for a 4pc box and 1pc box. Notice how sharp the real Denso box printing is?
Below: Another telltale sign is the print quality. It seems like a pretty decent scanner has been used, however it’s in no league compared to a print job that’s fresh from the original artwork file.
Below: On the 1x plug boxes, the font is different and the part number is followed by a #4 which indicates 4 pieces (except it’s a 1x plug box, right?)
Below: The cardboard material used is a cheaper type on the fake box. Also look at the corrugated fold lines too, they have a different patterns.
Below: Subtle differences again, printing sharpness, also notice that the curved edge on the thumb flap is a different shape.

This is where it gets hard to tell them apart. There’s no doubting that these are high quality copies, however to trained eyes and with genuine Denso’s on hand from our stock, the differences are fairly obvious.
Two Below Pics: The centre electrode tip definitely don’t feature a laser welded iridium tip, they appear to be made of a nickel alloy instead which has been machined down.
Below Pic: The crush washer is almost identical, however by looking at the centre recess you’ll notice the genuine Denso has a much deeper groove between the top and bottom rings. The metal areas around the punch letter stamping appear more swollen than the real plug also.
Below Pic: Font style on the part number is very authentic looking, this is a clear sign of tracing paper being used and then transferred to Photoshop for touch up.
Update: August 2018
During the last month or so, Denso has gradually started phasing in a new Iridium Power packaging design. The boxes below are 100% genuine, directly from Denso.
