Product Details

NGK has long supplied original equipment spark plugs for domestic and import vehicles, and this V-Power spark plug reflects that OE-focused approach. The BKR5EY-11 / 6745 configuration uses a standard nickel ground electrode and copper core center electrode to support dependable combustion in engines that require a conventional flat-seat plug. For fitment-specific service, this plug is used on 2002-2003 Isuzu Axiom, 2001-2002 Chevrolet Tracker, 1996-2002 Isuzu Rodeo, 2001-2002 Isuzu Rodeo, 2001-2002 Isuzu Rodeo Sport, 1996-2002 Isuzu Trooper, 1999-2001 Isuzu VehiCROSS, 1998-2000 Isuzu Amigo, and 1998-2000 Isuzu Rodeo applications. This part cross-references 1N04-18-110 and 22401-2J200 for the same application.

What This Spark Plug Helps Address

• Misfire conditions caused by worn or fouled spark plugs
• Hard starting related to weak ignition output
• Rough idle from inconsistent spark delivery
• Reduced throttle response from degraded plug performance
• Maintenance intervals requiring a replacement spark plug for Isuzu Rodeo, Trooper, or Chevrolet Tracker service

Installation Notes and Tips

Confirm the engine’s specified gap before installation. Some listed applications call for 0.042 inches, 0.044 inches, or 0.040 inches, so set the gap to the vehicle requirement rather than relying only on the pre-gap. Verify the seat type, thread diameter, reach, and terminal style against the original plug before installation. Use proper torque procedures and inspect ignition wires or coil boots during service to avoid repeat misfire concerns.
