DENSO’s patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures.
Are DENSO U groove spark plugs pre gapped?
DENSO spark plugs are manufactured with a pre-set gap. With nickel plugs, especially with motorcycles, the gap may need adjustment. Always use a special spark plug gapping tool to change the gap.
Which is better NGK or DENSO?
Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in Denso plugs shrinks more than an NGK. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.
How many miles are DENSO Spark Plugs good for?

How do you gap a Denso Spark Plug?
To increase the gap size:
- Step 1: Use needle nose pliers or spark plug gapping tool to bend the ground strap up to the desired height. DO NOT LET THE PLIERS OR GAPPING TOOL TOUCH THE IRIDIUM CENTER ELECTRODE OR PORCELAIN.
- Step 2: Re-check the gap with a calibrated gapping tool.
