NGK 93802 Spark Plug

NGK Laser Iridium Spark Plug Overview

NGK Laser Iridium High Ignitability Spark Plug 93802 is built for OE-style ignition performance with long service life. It uses an iridium-tipped center electrode, a platinum ground electrode tip, and a fine-wire design to support consistent spark delivery in modern distributorless ignition systems.

This spark plug is a direct-fit service part for select Nissan and Mitsubishi applications, including the Nissan Altima, Nissan Sentra, Nissan Rogue, and Mitsubishi Outlander. If you are replacing worn plugs on a 2020-2023 Nissan Sentra or a 2022-2024 Mitsubishi Outlander, part number 93802 is built to match the specified service interval and factory-style requirements.

Product Details

NGK’s Laser Iridium High Ignitability line is engineered for factory-style ignition performance where durability and stable combustion matter. The iridium center electrode is paired with a platinum ground tip and a dual fine electrode layout to promote consistent spark characteristics over time. A copper core and pure alumina ceramic insulator help manage heat, while the resistor design supports cleaner ignition operation in modern engine management systems. Part number 93802 is also identified as DILKAR7Q11.

This part cross-references Anchor 3529 for the same application.

Common Issues This Spark Plug Can Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from weak or inconsistent ignition output
• Misfire conditions related to electrode wear
• Reduced throttle response from degraded spark quality
• Service interval replacement on OE-recommended maintenance schedules
