A Guide to Spark Plug Replacement for the 2017-2024 Nissan Titan
Keep your Titan's 5.6L V8 running strong by understanding when and how to replace your spark plugs.
- Replace your Titan's spark plugs every 105,000 miles as recommended by Nissan.
- NGK is the OEM supplier; using their Laser Iridium or Iridium IX plugs is the safest bet for performance and compatibility.
- Symptoms like a rough idle, poor acceleration, and a drop in MPG are strong indicators of worn spark plugs.
- A flashing Check Engine Light signals a severe misfire that requires immediate attention to avoid costly damage.
Is It Time for New Spark Plugs?
Worn-out spark plugs can cause noticeable problems in your Titan. If you experience any of these issues, it might be time for a replacement. A failing plug can't create the strong spark needed to burn fuel properly in the engine's cylinders.
Symptoms of Failing Spark Plugs
- Rough Idle: Your truck may shake or vibrate more than usual when stopped. This happens because one or more cylinders may be misfiring.
- Poor Acceleration: If your Titan feels sluggish or slow to respond when you press the gas, weak spark could be the cause.
- Reduced Fuel Economy: When spark plugs are fouled, they can't ignite all the fuel in the cylinder, leading to wasted gas and more trips to the pump.
- Engine Misfires: You might feel a hesitation or stumble from the engine, sometimes accompanied by a popping sound. A flashing Check Engine Light often indicates a misfire.
- Difficulty Starting: Weak plugs struggle to create the initial spark needed to start the engine, especially in cold weather.
Check Engine Light Codes
The most common trouble codes for spark plug issues are P0300 (Random/Multiple Cylinder Misfire) or P0301 through P0308 (indicating a misfire in a specific cylinder, e.g., P0301 for Cylinder 1). A flashing light signals a severe misfire that can damage your catalytic converter, a very expensive repair.
Choosing the Right Aftermarket Spark Plugs
Your Titan came from the factory with high-quality iridium spark plugs. When choosing a replacement, it's best to stick with this type for longevity and performance. While OEM parts are always a safe bet, several aftermarket brands offer excellent quality, often at a better price.
Brand Quality Tiers for Your Titan
- Best (OEM Equivalent): NGK
NGK is the Original Equipment Manufacturer (OEM) for Nissan, meaning they made the plugs that were in your truck when it was new. Their Laser Iridium and Iridium IX series plugs are considered the top choice for performance and durability, designed to meet Nissan's exact specifications. Many owners and mechanics recommend sticking with NGK for guaranteed compatibility. - Better (High-Quality Alternative): Bosch
Bosch is a highly respected German brand known for its engineering. They produce Double Iridium spark plugs that are an excellent alternative to NGK. While very common in European vehicles, their plugs provide reliable, long-lasting performance in the Titan's V8 engine. - Good (Standard Replacement): Champion
Champion is a well-known American brand that also offers iridium and platinum plugs that fit the Titan. They are a reliable, budget-friendly choice that will restore performance, though they may not have the same OEM-level reputation for Japanese vehicles as NGK.
| Category | Price Range (Set of 8) | Notes |
|---|---|---|
| New Aftermarket (Iridium) | $64 - $236 | Price per plug ranges from $8 to $29.50. NGK and Bosch are typically in the upper half of this range. |
| New OEM (Nissan-Branded) | $210 - $315 | These are typically NGK plugs sold in Nissan packaging at a higher price. |
| Shop Labor | $172 - $304 | Labor costs can vary by location and shop. |
Pro Tip: Replace Coils with Plugs?
While you have everything apart, you might consider replacing the ignition coils (also called coil packs). However, coils are durable and generally don't need to be replaced unless they have failed. If you are not experiencing misfire codes specific to a single cylinder after replacing the plugs, you can likely leave the original coils in place to save money.
