FAQ

What vehicles are compatible with the Denso IK24 spark plug?

The IK24 is a vehicle‑specific fit plug designed for many passenger cars that use a 14 mm thread size. Check your vehicle’s service manual or the Denso fit guide to confirm compatibility.

How does the iridium electrode improve engine performance?

Iridium’s high melting point and durability allow for a finer electrode tip, which creates a more precise spark. This leads to better fuel combustion, reduced emissions, and longer plug life compared to standard copper plugs.

Can I install this plug myself?

Yes, the plug’s standard 14 mm thread and clear gap specifications make it suitable for DIY installation with basic tools. Always follow torque specifications in your vehicle’s service guide.

What is the benefit of the laser‑welded construction?

The 360‑degree laser welding process creates a uniform, strong bond between the iridium electrode and the plug body, preventing electrode movement and ensuring consistent performance throughout the plug’s lifespan.

How often should I replace the Denso iridium spark plug?

Due to the durability of iridium, replacement intervals typically range from 60,000 to 100,000 miles, depending on driving conditions and manufacturer recommendations.
