Nissan's Titan and Frontier trucks use robust V6 and V8 engines that are known for durability. Here's how to keep their ignition systems in top shape.
Nissan Titan 5.6L V8 (A60/A61)
The 5.6L Endurance V8 is a smooth, powerful engine. NGK Laser Iridium plugs are the OEM fit and highly recommended. The engine benefits from iridium's longevity — 60,000-mile intervals mean less frequent plug changes for this work truck.
Nissan Frontier 3.8L V6 (2022+)
The newer Frontier's 3.8L V6 is shared with the Pathfinder. NGK Iridium IX plugs provide excellent performance in this engine, delivering smooth idle and sharp throttle response.
Older Frontier 4.0L V6
The workhorse 4.0L V6 (2005–2021) responds well to NGK Iridium IX or Champion Iridium plugs. This engine is durable — maintaining the plug change schedule keeps it that way.
Towing and Hauling Effects
Under tow load, cylinder temperatures rise and plug wear increases. Nissan truck owners who regularly tow should inspect plugs at slightly shorter intervals than the OEM recommendation.
