Fiada Compression Tester Kit, 9-Piece — 300 PSI Dual-Unit Gauge & Spark Plug Tester (Black)

Fiada's 9-piece automotive compression tester kit is a complete, portable set that lets you measure cylinder pressure and verify ignition spark quickly and accurately for cars and motorcycles.

The Fiada kit pairs a 300 PSI dual-unit compression gauge with a spark plug tester and a range of adapters so you can inspect engine health without a trip to the shop. The tools are stored in an ABS carrying case and built to fit most spark plug threads and small-bore engine ports, making this set a practical addition to any garage, mobile mechanic bag, or rider toolkit.

How do I use the compression gauge to check cylinder health?

Use the compression gauge by removing the spark plug, attaching the correct adapter, and cranking the engine while the throttle is open. Readings on the 3-inch dial show pressure in both PSI and kg/cm² so you can compare cylinders or check against manufacturer specs.

• Remove fuel pump/fuel-injection fuse and disable ignition before testing.
• Hand-thread the gauge adapter into the spark plug hole to avoid cross-threading.
• Crank the engine four full revolutions with throttle depressed for a stable reading.
• Compare readings across cylinders to identify low-compression issues.

What adapters are included and which engines do they fit?

The kit includes one straight rubber cone, one curved rubber cone, four brass adapters, and a 14-inch extension hose to cover a variety of spark plug and cylinder types. These fittings accommodate most motorcycle and automotive spark plug threads and recessed ports found on small engines.

• Straight and curved rubber cones for irregular or recessed ports.
• Four brass adapters to match common thread sizes and reach tight spaces.
• 14-inch extension hose for hard-to-reach cylinders or angled placement.

How does the included spark plug tester help diagnose ignition problems?

The spark plug tester visually confirms whether ignition voltage is reaching the plug by producing a visible spark under load. It’s a simple, fast way to detect faulty wires, poor connections, damaged plugs, or ignition timing issues without removing components for bench testing.

• Connects inline with the spark plug to display spark presence safely.
• Helps isolate ignition faults like bad coils, wires, or plugs.
• Works on most engines that use spark plugs, from motorcycles to cars.

What features improve durability and ease of use?

The gauge has a 3-inch dial with dual PSI and kg/cm² units and a scratch-resistant cover plus a rubber boot for impact protection. All components store neatly in an ABS case so parts stay organized and protected when not in use.

• 300 PSI range covers common passenger and light-duty engine compression values.
• Rubber-protected dial resists drops and shop wear.
• Compact ABS case with foam layout for secure transport and storage.

Who is this for: The Fiada 9-piece compression tester kit is designed for DIY mechanics, mobile technicians, motorcycle riders, and small-engine owners who want a reliable diagnostic toolset. It’s suitable for anyone who needs quick compression comparisons, basic ignition checks, or a portable kit that fits in a garage drawer or trunk — no specialized training required, just common-sense safety precautions and basic engine knowledge.

Safety reminder: Always disconnect fuel and ignition systems before testing and never touch the spark plug tester or gauge fittings while the engine is cranking. If you’re unsure about a result, consult a professional mechanic.
