Denso Iridium IK24 Spark Plugs Part # 5311 (one step colder) box of 4 spark plugs
Increase your cars performance with Denso Iridium Spark Plugs! The super small Iridium electrode creates a super hot spark that increases gas mileage and performance by burning fuel more efficently.
The IK24 is one step colder for the Acura RSX Type S. They are great for turbo, supercharged or nitrous applications requiring a one step colder plug to avoid detonation and/or plug damage due to the higher cylinder temperatures.
Optimize Your Ignition System
Your sport compact engine needs a true performance spark plug not another gimmick, particularly if you have a high performance application that is turbocharged, supercharged or nitrous-enhanced. These types of engine modifications create intense conditions within your cylinders, conditions that will kill a standard OE plug and bring an ordinary performance plug to its knees.
Design Features you Won’t Find in any Other Plug:
• A 0.4mm center electrode, the world’s smallest. That’s 50% smaller than any other plug available and 2x smaller than a platinum OE plug.
• A patented U-Groove ground electrode with a tapered cut. This means Iridium Power produces a precise flame front, which reduces engine misfires.
• A patented Iridium alloy that can withstand temperatures of over 4,000° F, and is 6x harder and 8x stronger than platinum.
A Potent Formula
The combination of features means this plug drains less voltage from your ignition system. According to SAE Technical Paper Series:
“It takes 5,000 volts less to fire a DENSO Iridium Power spark plug versus a conventional platinum spark plug.”
It’s easy to see why the DENSO Iridium Power spark plug is the ultimate in performance spark plugs. It’s the only spark plug that maximizes your engine performance.
