ignition and acceleration characteristics.

The IRI series are interchangeable as follows:

IRIMAC = DCPR#E
IRITOP = BCPR#E
IRIWAY = BKR#E

The ground electrode of Iridium NGK Iriway is tapered cut to provide a better flame spread generated by combustion, raising compressions and ensuring a cleaner burning.
These spark plugs for which alloy has been revised to provide a better resistance, were mainly made by NGK in response to requests directly from the competition (Rally, Circuit, Street Race...).
