The 2015 Rogue's 2.5-liter QR25DE engine uses spark plugs with a 14mm thread and a standard gap of 0.043 inches (about 1.1 mm). For best reliability, choose iridium or platinum plugs from reputable brands such as NGK or Denso, and verify the exact OEM specification for your vehicle’s VIN before purchase.
Engine size and plug basics
Understanding the engine helps identify the correct plug size. The QR25DE is a four-cylinder inline engine used in the 2015 Rogue, and it requires plugs that fit the threading and heat range of the design. Using the wrong plug can lead to misfires, reduced fuel efficiency, or longer-term engine wear.
Core plug size and gap details
Before buying plugs, confirm these core specs stay consistent with the QR25DE engine:
- 14 mm thread diameter
- Gap of 0.043 inches (1.1 mm)
- Commonly available as iridium or platinum variants
- Brands typically recommended: NGK or Denso
Note that some vehicles or VINs might have slightly different gap tolerances or heat-range requirements; always cross-check with the OEM part number or your current plugs.
Installation notes
When installing, torque the plugs to the manufacturer’s specification and verify the gap before installation if you’re using pre-gap plugs. For many QR25DE applications, a light torque in the range of 13–19 ft-lbs (18–26 Nm) is typical, and you should re-check the torque after a short engine run to settle the threads.
Summary
In short: the 2015 Nissan Rogue’s 2.5L engine uses 14mm spark plugs with a 0.043-inch gap. Choose iridium or platinum plugs from NGK or Denso, and verify the exact OEM part number for your vehicle. Always follow the service manual for torque specs and replacement intervals to maintain optimal performance.
