Champion Aerospace Spark Plugs
FAA/PMA Approved Aviation Spark Plugs | Authorized Distributor & Stockist

The First Choice in Aviation Spark Plugs Since 1943
![]() |
Airpart Supply is an authorized distributor and stockist for Champion Aerospace spark plugs, providing FAA/PMA approved ignition components for general aviation aircraft worldwide. Champion Spark Plugs have been the first choice of aviation technicians and aircraft maintenance professionals since the earliest days of aviation. When you ask a technician what spark plug they prefer and rely upon, they will most likely say Champion. Advanced-engineered Champion Aerospace spark plugs are designed for critical performance differences, far beyond the ordinary. These aircraft engine components stand up to high temperatures, pressures, and deposits that would compromise lesser spark plugs. Whether you're maintaining Cessna, Piper, or other general aviation aircraft, Champion spark plugs deliver proven reliability. Compatible with Lycoming and Continental engines, Champion spark plugs are the preferred choice for both OEM and aftermarket applications. |
Iridium "S" Technology: Superior Performance
Longer lasting than platinum spark plugs, Iridium "S" plugs resist lead attack and provide better scavenging than standard platinum plug designs. Iridium "S" offers exceptional performance, even under the most demanding conditions encountered in general aviation operations.
As the preferred supplier of spark plugs for general aviation aircraft, Champion Aerospace designs, engineers, and manufactures piston-engine ignition components for both OEM and aftermarket applications. Every spark plug manufactured has built-in design advantages that assure longer life and greater reliability.
Key Features & Manufacturing Excellence
Ceramic Manufacturing Expertise
Champion designs and manufactures all ceramic insulators in Liberty, South Carolina, USA. This enables the use of ceramic materials optimized specifically for aerospace applications and ensures superior quality control throughout the manufacturing process.
Superior Corrosion Prevention
All Champion spark plugs feature two layers of corrosion protection: nickel-zinc plating and high-temperature epoxy paint. Competitor spark plugs made of stainless steel without paint are 40% more likely to rust and corrode during their 300-hour service life.
Complete Quality Control
- Champion spark plugs are designed, engineered, manufactured, tested, inspected, and packaged all under one roof. There is no outsourcing or outside companies involved in production.
- 100% of plugs are screened on an automated spark tester, ensuring consistent electrical performance.
- 100% of spark plug gaps are manually checked before shipping to guarantee proper installation and performance.
Engineering Design Features
- Fired Glass Seal: Provides positive retention of center wire and prevents gas leakage in Lycoming and Continental engines
- Plated Threads: Prevents seizing and ensures easy installation and removal during routine maintenance
- Nickel Alloy Electrodes: Provide excellent resistance to spark and heat erosion
- Fired-In Suppressor Seal Resistor: Prevents wear from voltage drain for prolonged plug life
- Ceramic Insulator: Excellent thermal properties resist cracking under extreme conditions
