Automotive Compression and Spark Plug Tester Kit

Revised Content:

【A Comprehensive Kit for Car Testing】: This 9-piece cylinder testing kit includes 8 compression tools and 1 spark plug tester. The complete package comprises 1 SPARK PLUG TESTER, 1 300PSI DUAL UNITS GAUGE, 1 STRAIGHT RUBBER CONE ADAPTER, 1 CURVED RUBBER CONE ADAPTER, 4 BRASS ADAPTERS, and 1 14-inch EXTENSION HOSE. This comprehensive set allows you to easily test your car's condition by yourself.

【Spark Plug Tester: An Essential Diagnostic Tool】: The spark tester is a must-have diagnostic tool for engines with spark plugs. You can quickly and easily diagnose ignition or engine outboard motor issues, as well as faults in the fuel delivery system. If the tester detects a spark, it will mirror the spark, allowing you to identify problems such as dirty spark plugs, defective points, bad cables, or poor connections.

【300psi Dual Units Gauge with 3" Dial】: The compression gauge features dual units (0 - 300 PSI and 0 - 20 kg/ cm square) and a large, easy-to-read 3-inch dial. The gauge is protected by an anti-scratch coating and rubber casing to absorb shocks. Additionally, all the items are neatly stored in an ABS case for easy access, and the fittings can accommodate the needs of most engines.

【Safe and Easy to Use】: To use the kit, first, remove the fuel pump and fuel-injection fuses, disconnect the main wire to the coil and spark plug wires, and remove the spark plugs. Then, thread the compression gauge into a spark plug hole by hand. Finally, turn on the ignition, depress the throttle, and crank the engine four revolutions to obtain accurate data.

Please ensure that all parts are properly installed before conducting the cylinder pressure test. Do not touch the spark plug tester or any part of the test units while the ignition is on. Always switch off the engine and remove the key before handling the equipment. If you have any further questions about this product, do not hesitate to contact us, as we are always happy to assist.
