Description
SET OF 4 DENSO IRIDIUM SPARK PLUGS IK20
STANDARD HEAT RANGE FOR STOCK / MILDLY MODIFIED CARS WITH INTAKE / EXHAUST / MANIFOLD MODIFICATION.
FOR ENGINES WITH CAMSHAFT UPGRADES AND TURBO CONVERSIONS USE DENSO IK22 SPARK PLUGS WHICH ARE A HIGHER HEAT RANGE
Quality Iridium plugs from Denso. Iridium plugs are proven to provide several advantages over conventional copper plugs:
a) Consistent spark every time, improving throttle response and acceleration. The use of iridium alloys allows consistency in plug performance
b) Increased engine power. Through consistent performance, expect a 1-3% increase in engine power, as iridium plugs allow the engine to run more efficiently.
c) Improved fuel economy. Iridum plugs promote engine efficiency which in turn relates to better fuel economy.
d) Long life. Iridium spark plugs will last up to three times longer than conventional copper plugs.
Denso’s 0.4mm electrode provides for efficient ignition using long lasting Iridium construction.
A larger center electrode means a greater cooling effect and poorer ignitability.
On the other hand, the 0.4mm diameter iridium center electrodes have an extremely small cooling effect, reducing non-firing and realizing assured ignitability, the basic function of a spark plug.
IRIDIUM POWER best demonstrates its performance improvement during acceleration.
IRIDIUM POWER has a 0.4 mm diameter iridium center electrode and a specially shaped ground electrode.
These features combine to achieve higher ignitability and require lower spark voltage than ever before.
This enables high-response driving with fewer misfires than under higher required voltage spark conditions, and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs
