Comparison points and tradeoffs
When comparing Denso (5331) ITF20 Iridium Power Spark Plug, (Pack of 1) with other Spark Plugs options, use this source-backed detail as the primary discriminator: U-groove and taper cut ground electrode: provides faster spark flame growth and lessens heat quenching.
Use this second fact to evaluate the tradeoff: To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. A third point to compare across alternatives is: Increased performance with World’s smallest Iridium Center Electrode (0.4mm).
Alternative-selection boundary
Choose an alternative when its stated identifiers, application, package, or specifications better match the requirement; no unverified competitor claim is introduced here.

Increased performance with World’s smallest Iridium Center Electrode (0.4mm). To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO’s patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.
