Installation Notes

Verify the vehicle-specific gap before installation. Listed applications call for different gap settings depending on the engine and model year, including 0.044 inches, 0.040 inches, and 0.036 inches on certain vehicles. Confirm thread diameter, reach, seat type, and heat range against the original plug before installing NGK 3271. Use the exact fitment notes for your vehicle, such as Fits 2003-2005 Honda Civic, N/A, or Fits 1999-2010 Jeep Grand Cherokee, N/A, and follow the OE gap specification for the application.
