HKS S-Series Super Fire Racing Spark Plugs
ALL PLUGS SOLD INDIVIDUALLY
HKS S-Series Super Fire Racing spark plugs are high performance Iridium plugs designed to handle advanced levels of tuning and still offer easy start-up and smooth idling.
S-Series Super Fire Spark Plugs Feature:
- 0.4mm diameter Iridium plug electrode core
- U-shaped grooved electrode
* S-Series Super Fire Spark Plugs are recommended for smooth cold starting, response and acceleration.
The Iridium alloy is used because of its durability and reliability. On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration. The Iridium plugs are available for multiple applications and offered in colder heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.

HKS M-Series Super Fire Racing Spark Plugs
ALL PLUGS SOLD INDIVIDUALLY
HKS M-Series Super Fire Racing spark plugs are high performance Iridium plugs designed to handle advanced levels of tuning and provide Improved ignition performance, durability and anti-carbon build-up
M-Series Super Fire Spark Plugs Feature:
1. 0.6mm Iridium Alloy Center Electrode
Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability.
2. Outer Electrode with Platinum Chip
The Outer Electrode incorporates a square platinum chip which improves durability, and when combined with the iridium center electrode boosts ignition performance.
3. Short Type Outer Electrode (Anti-Vibration)
The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration. This anti-vibration design improves longevity of the outer electrode.
4. Thermal Edge
After long idling or various combustion conditions carbon buildup can occur causing misfires. The Thermal Edge of the ceramic insulator will discharge to help decrease carbon deposits.
5. Spark Support Gap
Discharges will occur in the Spark Support Gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.
*M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.

 HKS Twin Power DLI II, Honda

HKS Twin Power DLI II
The Twin Power ignition amplifier incorporates both the CDI and transistor method ignition to provide optimum spark duration and maximum voltage output, resulting in crisper throttle response and a smoother engine powerband. The CDI method, capacity discharge ignition, provides maximum voltage by transferring all stored energy in the capacitor to the ignition coil so that the ignition current can buildup quickly, thus making the Twin Power very effective in the higher revs where a normal spark would tend to diminish. This strong rapid spark prevents the high rpm ignition miss that reduces peak power. The transistorized method generates high voltage by using transistors to cut off current to the coil, thus allowing for a long energy discharge. This longer spark duration allows the Twin Power to improve lower RPM throttle response and torque. The combination of the CDI and the transistor method incorporates two distinct systems into one high performance unit, hence the designation of Twin Power. The Twin Power produces a spark output that is typically 1.5-2.5 stronger than of the stock ignition system and consumes about 35% less power input than other ignition amplifiers. Each compact and attractive Twin power unit is constructed of durable anodized aluminum and sealed to prevent corrosion from moisture. General wiring harnesses are included in each unit to aid in installation and mounting. Vehicle Specific wiring harnesses are also available for certain models to further aid in installations that require intricate integration.(CARB E.O. # D-186-29)
Dimensions: All Twin Power Units, except for DLI II, are 91mm (L) x 80mm (W) x 34.5mm (H) and weighs Approximately 430g (~15.2oz)
Note: HKS Twin Power Units are not compatible with Non-Resistor Spark Plugs
