RHM38E – Champion Aerospace Aviation Spark Plug

Available now on the Airparts.aero Marketplace.

Overview

The Champion RHM38E is a premium, fine-wire Iridium electrode aviation spark plug engineered for pilots who demand the highest level of performance and reliability from their piston engines. As a leader in ignition technology, Champion Aerospace designed the RHM38E to provide exceptional service life, superior fouling resistance, and optimized ignition characteristics, especially in high-compression and high-performance engines. Its advanced materials and construction ensure consistent, powerful sparks under the demanding temperature and pressure conditions found within aircraft engine cylinders. This makes it a strategic upgrade for reducing maintenance and enhancing engine efficiency.

Key Features

• Fine-Wire Iridium Electrode: Features a 0.060" diameter fine-wire Iridium center electrode that requires lower voltage to fire. This results in easier, quicker starting in all conditions and significantly reduces stress on the magnetos and ignition harness.
• Superior Anti-Fouling: The fine-wire design is less prone to carbon and lead fouling compared to traditional massive electrode plugs, making it ideal for operations involving frequent low-power settings or rich mixture operations.
• Extended Service Life: The extreme hardness and high melting point of Iridium, combined with a platinum ground electrode, dramatically reduces spark erosion, providing a substantially longer operational life than conventional plugs.
• Proprietary Glass Seal Resistor: Incorporates a proprietary semi-conductor resistor material to minimize radio frequency interference (RFI) that can affect avionics. The robust glass seal ensures full operating voltage is delivered to the spark gap.
• Solid Copper Core: A solid copper core electrode design (common to Champion plugs) provides superior heat conductivity, ensuring the plug operates within the optimal temperature range to prevent both fouling and pre-ignition.

Applications

The RHM38E spark plug is an ideal choice for a variety of demanding operational environments:

• High-Performance Engines: Excels in high-compression engines where spark energy and timing are critical for developing maximum horsepower.
• Leaded Fuel Operations: The anti-fouling characteristics provide a significant performance margin in engines operating on 100LL Avgas.
• All-Weather Operations: The low voltage requirement ensures more reliable starts during cold weather.
• Maintenance Reduction: For fleet operators and private owners seeking to extend maintenance intervals and reduce the labor associated with cleaning and rotating plugs.

Why Choose RHM38E?

Investing in the Champion RHM38E spark plug is an investment in engine health and reliability. The advanced fine-wire Iridium technology translates directly into tangible benefits: lower long-term maintenance costs, improved fuel efficiency through more complete combustion, and greater confidence in engine starting and performance. While the initial cost is higher than a massive electrode plug, the extended service life and superior resistance to fouling provide a lower total cost of ownership and a higher level of performance that pilots can depend on.

Upgrade your engine's ignition system with the proven performance of the Champion RHM38E fine-wire spark plug. Visit Airparts.aero to place your order today and experience the difference in reliability and efficiency.

The Champion RHM38E represents a significant technological advancement in piston engine ignition systems. Unlike massive electrode plugs that have a large surface area prone to accumulating lead and carbon deposits, the RHM38E's fine-wire Iridium tip concentrates electrical energy, allowing it to fire at a lower voltage and physically burn off deposits before they can solidify and cause fouling. This self-cleaning characteristic is critical for maintaining engine performance across a wide range of power settings. For engine models specified in Lycoming Service Instruction No. 1042 or Continental Service Information Letter SIL99-1, upgrading to the RHM38E can resolve persistent fouling issues, leading to smoother engine operation and greater peace of mind. At Airparts.aero, we provide direct access to these mission-critical components, ensuring your engine is equipped with the best ignition technology available.

Note: Always install spark plugs in accordance with the engine manufacturer's maintenance manual and Champion Aerospace guidelines. Verify part number applicability before installation. Use a calibrated torque wrench and new copper gaskets for proper installation.Description:   Spark Plug

Product Overview: 

Ignition at Its Highest Level with the Champion Aerospace RHM38E

Champion's range of spark plugs is a monument to unsurpassed quality and innovation, as evidenced by the fact that it is trusted by industry heavyweights as well as aviation enthusiasts. Champion has established an unrivaled record in the manufacturing of aviation spark plugs, having left its imprint on a wide variety of aircraft, ranging from the nimble Cessna and Piper to the cutting-edge Cirrus and Mooney.

Principal Attributes:

Unrivaled Design Sophistication Each and every Champion spark plug features built-in design subtleties that have been specifically tuned for maximum performance. The fusing of plated threads guarantees that there will be no seizing, which enables installations and removals to go smoothly.

Protected on Both Sides: The spark plug is coated on both sides with a corrosion inhibitor, which not only makes it more durable but also ensures that it will last longer than other spark plugs on the market.

Excellence in Composites Champion spark plugs are the paragon of dependability because they are made from a combination of hardy materials. Its silicon carbide resistor works in harmony with the burned glass seal to efficiently negate voltage drains and gas leakages, which are variables that may put both the plug and the engine in danger.

The copper core in the center of the spark plug provides remarkable heat transmission, making it an excellent heat management component. This, in conjunction with the aluminum oxide insulator and the nickel alloy electrodes, serves to protect the plug from any potential fractures that may occur.

Choose the Champion Aerospace RHM38E for an experience with ignition that not only satisfies but also reimagines the standards set by the industry. Raise the bar for your flying performance and soar further than ever before with the unflappable dependability of Champion.
