Fiada 9-Piece Compression and Spark Plug Tester Kit, Red — 0–300 PSI Gauge & Probe in ABS Case

Fiada's 9-piece automotive tester kit combines a 0–300 PSI compression gauge and a spark plug probe in a single portable case for quick engine diagnostics.

This compact kit gives DIY mechanics and professional technicians a ready-made set of adapters, a clear 3-inch dial, and a spark tester probe to check cylinder compression and ignition at the spark plug. The included adapters and extension hose make the kit compatible with a wide range of gasoline engines—cars, motorcycles, ATVs, boats and small engines—while the protective ABS case keeps everything organized and transportable.

How will this kit help me diagnose compression issues?

The compression gauge lets you measure cylinder pressure precisely across a 0–300 PSI range so you can compare cylinders and identify worn rings, leaking valves, or head gasket problems. Quick, repeatable readings help narrow down whether an engine needs a teardown or simple maintenance.

• 3-inch dual-scale gauge: 0–300 PSI and 0–20 kg/cm² for easy cross-reference
• Four brass threaded adapters for different spark plug sizes
• Straight and curved rubber cone adapters for non-threaded holes
• 14-inch extension hose to reach recessed spark plug locations

What does the spark plug tester probe reveal?

The spark tester makes ignition faults visible by showing if a spark is present at the plug connection. It helps you quickly distinguish between ignition and fuel delivery issues without disassembling the ignition system.

• Simple visual check of spark continuity and strength
• Works with standard spark plug wires and most ignition systems
• Useful for finding fouled plugs, broken leads, or weak spark
• Safe, handheld operation when used with engine shut-off precautions

How do I use the compression tester safely and correctly?

Follow basic safety steps: disable fuel and ignition, remove spark plugs, hand-thread the gauge into the plug hole, and crank the engine for consistent readings. The kit instructions explain the sequence; observing safety prevents electrical or mechanical hazards.

• Remove fuel pump/fuel-injection fuse and disconnect coil/spark wires first
• Hand-thread gauge into spark plug hole—avoid cross-threading
• Crank engine four revolutions at wide-open throttle for stable readings
• Do not touch the tester or wiring with ignition on; remove key before handling

What components are included and how are they stored?

The kit ships with nine pieces stored in a molded ABS carrying case so parts stay protected and easy to transport. The set covers most common gasoline engine needs, reducing the number of separate tools you must carry.

• One 3-inch 0–300 PSI spring-button gauge with rubber protection
• One straight rubber cone adapter and one curved rubber cone adapter
• Four brass threaded adapters plus a 14-inch extension hose
• One spark plug tester probe and a durable ABS storage case

Who is this for? The Fiada 9-piece compression and spark tester kit is designed for home mechanics, mobile technicians, small repair shops, and anyone who services gasoline engines on cars, motorcycles, ATVs, marine outboards, and garden equipment. It suits people who need a reliable, portable diagnostic solution to quickly check cylinder health and ignition performance without specialized shop equipment.
