The Nissan Skyline R33 and R34 require precision when it comes to spark plug selection, and the Range 6 Spark Plug for RB20 and RB25 engines delivers the reliability and performance your motor depends on. This original Nissan NGK PFR6G-11 plug is engineered with the correct heat range to handle the demands of turbocharged and performance-driven setups. A heat range 6 plug is designed to transfer heat effectively from the combustion chamber to the cylinder head, making it the ideal choice for engines that experience higher combustion temperatures and pressures.
Selecting the proper heat range is critical to engine longevity and performance. In naturally aspirated engines, hotter plugs may work to prevent fouling, but in turbocharged applications like the RB20DET and RB25DET, colder plugs such as the Range 6 are necessary to manage heat and avoid pre-ignition or detonation. Running the correct spark plug ensures stable combustion, reduces the risk of misfires, and helps maintain consistent power delivery under demanding conditions.
At Terra Firma Automotive, we understand that every detail matters when it comes to keeping your Skyline performing at its best. That’s why we offer only genuine Nissan spark plugs that provide factory-correct fitment and trusted durability. With the proper spark plug in place, you protect your RB engine from unnecessary wear while ensuring smooth operation and reliable performance whether on the street or at the track.
