Spark Plugs

Spark plugs play a critical role in aircraft engine performance, influencing everything from starting reliability to fuel efficiency and smooth operation. This collection brings together a curated range of aviation spark plugs used across general aviation, training aircraft, and commercial piston operations throughout New Zealand. Each plug is selected for durability, ignition consistency, and compatibility with common Lycoming and Continental engines.

Our Champion range includes popular massive‑electrode plugs such as RHB32E, RHM38E, REM40E, REM38E, and REM37BY, each designed to deliver stable ignition and long service life. These plugs are widely used in flight‑training fleets, private aircraft, and commercial piston operations due to their proven reliability and strong performance across varied operating conditions. Champion’s copper‑core construction and robust insulator design help maintain consistent spark energy, even in high‑temperature environments.

We also stock the Tempest UREM38E, a massive‑electrode plug known for its modern manufacturing process, improved resistor design, and strong field reputation for smooth engine operation. Many maintainers choose Tempest plugs as a performance‑focused alternative to traditional Champion models.

To support proper installation and maintenance, Pilot Shop also supplies 18mm copper spark plug gaskets in both single‑pack and 10‑pack options. These gaskets ensure correct sealing, heat transfer, and torque retention — essential for maintaining compression and preventing combustion leaks.

Every spark plug in this collection meets aviation specifications and manufacturer requirements, giving pilots and engineers confidence in long‑term engine reliability. Whether you’re performing scheduled maintenance, troubleshooting rough running, or stocking your hangar with essential consumables, Pilot Shop provides genuine aviation spark plugs backed by fast local shipping and knowledgeable support.
