NGK Iridium Spark Plug DPR8EIX-9 (2202) — Pack of 2, Fine Iridium Electrode for Long Life

The NGK 2202 (DPR8EIX-9) is an iridium spark plug sold in packs of two, engineered for reliable ignition and long service life in compatible engines.

NGK's DPR8EIX-9 iridium plug combines a fine iridium center electrode with precision manufacturing to deliver consistent spark performance. Supplied as a quantity of two per order, these plugs are intended for vehicle owners and technicians who need exact-fit replacements for applications that specify the 2202 part number. The compact iridium tip and robust construction are designed to sustain repeated ignition cycles while resisting wear.

What makes the DPR8EIX-9 different from standard plugs?

The DPR8EIX-9 uses an iridium center electrode, which is much finer and harder than conventional materials. That smaller electrode diameter allows for a more concentrated spark while offering increased durability under high temperatures. The plug also includes a precisely shaped ground electrode and quality ceramic insulation for stable performance.

• Iridium center electrode for a focused, consistent spark
• Durable ceramic insulator to resist heat and voltage leaks
• Precision-ground electrodes for stable ignition timing

How do these plugs help with everyday driving and maintenance?

Replacing worn or incorrect spark plugs with the correct DPR8EIX-9 can restore consistent combustion and ease cold starts. Regular replacement at manufacturer-recommended intervals helps maintain drivability and can reduce misfires. Because these plugs are sold in pairs, they are convenient when two-cylinder service or staggered replacement is required.

• Sold in packs of 2 for paired-cylinder or matched-replacement needs
• Helps maintain smooth idle and steady throttle response
• Reduces risk of ignition-related rough running when correctly fitted

Are there special installation or compatibility considerations?

Always check your vehicle’s service manual or parts catalog to confirm the DPR8EIX-9 / NGK 2202 is compatible with your engine before installation. Use the recommended gap settings and a torque wrench to secure the plug to the factory specification. If your engine previously used a different heat range or thread size, consult a mechanic to avoid mismatched parts.

• Verify vehicle fitment for NGK part number 2202 (DPR8EIX-9)
• Set and check spark plug gap per manufacturer specs before installation
• Tighten to correct torque to prevent damage to threads or seat

How long can you expect them to last and when should you replace them?

Longevity depends on driving conditions, engine tune, and service intervals, but iridium plugs generally last longer than standard plugs. Inspect plugs during scheduled maintenance and replace when electrodes show excessive wear, fouling, or if ignition symptoms appear. Follow your vehicle maker’s replacement interval as a baseline.

• Inspect during routine tune-ups for electrode wear or fouling
• Consider replacement if misfires, rough idle, or poor starts occur
• Use manufacturer intervals as the primary guide for replacement timing

Who is this for: The NGK 2202 (DPR8EIX-9) iridium spark plug, sold two per order, is aimed at vehicle owners, mechanics, and performance-minded drivers needing an exact-fit iridium replacement. It’s suited for engines that specify the DPR8EIX-9 part number or equivalent NGK 2202 designation, and for anyone seeking a durable, precision-manufactured plug for routine maintenance or upgrades. Always confirm compatibility with your engine’s specifications before purchase and installation.
