REM38E - Champion Aerospace Massive Electrode Aircraft Spark Plug

REM38E – Champion Aerospace Massive Electrode Aircraft Spark Plug

Available now on the Airparts.aero Marketplace.

Overview

The Champion Aerospace REM38E is a genuine OEM, massive electrode aviation spark plug, representing the industry benchmark for reliability, durability, and performance in a wide range of piston engines. As the world leader in aviation ignition, Champion has designed the REM38E to be a durable workhorse, providing consistent, powerful sparks under the demanding temperature and pressure conditions found within aircraft engine cylinders. It features a solid copper core for superior heat management and a proprietary glass seal, making it a trusted, time-proven choice for private owners, flight schools, and fleet operators.

Key Features

• Massive Electrode Design: Features a robust, two-prong massive electrode ground configuration. This heavy-duty design provides an excellent service life and high resistance to the thermal and electrical erosion caused by continuous, high-power engine operation.
  
• High-Conductivity Copper Core: A solid copper core is used in the center electrode. Copper's exceptional thermal conductivity rapidly dissipates heat from the firing tip to the cylinder head, which helps to prevent destructive pre-ignition and detonation, especially in high-compression engines.
  
• Proprietary Glass & Copper Seal: Utilizes a two-piece, shrink-sealed insulator with a proprietary glass and copper seal. This creates a monolithic, 100% gas-tight seal that ensures full combustion pressure is contained and that the maximum spark energy reaches the electrode tip without leakage.
• Built-in Resistor: The "R" designation signifies an integral resistor, designed to suppress radio frequency interference (RFI) that can affect the aircraft's communication and navigation radios.
• Legendary OEM Quality: As the original equipment spark plug for countless engines, it guarantees the performance, reliability, and quality standards specified by the engine manufacturer and required for FAA type-certified aircraft.

Applications

The REM38E spark plug is the ideal choice for a variety of operational environments:

• General Aviation Fleet: The standard, OEM-specified choice for the majority of privately owned and training aircraft.
• High-Performance Engines: The copper core provides an excellent defense against the high combustion temperatures generated in high-compression piston engines.
• Scheduled Maintenance: A critical consumable part that is cleaned, gapped, and rotated at regular intervals and replaced upon reaching its service limits.

Why Choose REM38E?

Reliable ignition is the most fundamental requirement for a safe and smooth-running engine. The Champion REM38E provides this reliability through decades of proven performance and engineering. Its robust design and superior materials provide a long, trouble-free service life. For owners and operators seeking the original, factory-specified component for their engine, the Champion REM38E is the definitive choice for certified performance.

The design of the Champion REM38E directly addresses the challenges of the piston engine combustion chamber. The massive electrode provides a large surface area of nickel alloy, which is resistant to wear but also acts as a heat sink at the firing tip. The solid copper core, extending from the terminal well deep inside the center electrode, provides a highly efficient thermal path to conduct heat away from the tip and into the aluminum cylinder head. This thermal management is critical; it keeps the spark plug within its designed "heat range," ensuring it stays hot enough to burn off carbon deposits but cool enough to prevent it from becoming a glowing ember that could cause pre-ignition.

Note: This is a flight-critical engine component. Installation must be performed by a certified A&P mechanic. The spark plug electrode gap must be properly set using a feeler gauge, and the plug must be installed with a new copper gasket and torqued to the value specified in the engine maintenance manual.Description:   SPARK PLUG
