About this item 【Complete Kit for Car Testing】: The 9pcs cylinder testing kit includes 8 x compression tools and 1 x spark plug tester. The total package features 1 x SPARK PLUG TESTER, 1 x 300PSI DUAL UNITS GAUGE, 1 x STRAIGHT RUBBER CONE ADAPTER, 1 x CURVED RUBBER CONE ADAPTER, 4 x BRASS ADAPTERS, and 1 x 14-inch EXTENSION HOSE, allowing you to easily test the car’s condition by yourself. 【Extra Value with Spark Plug Tester】: The spark tester is an essential diagnostic tool for any engine with a spark plug. It enables you to quickly diagnose ignition or engine outboard motor issues and identify faults in the fuel delivery system. If a spark is being sent, the tester will mirror the spark and light up, helping you find dirty spark plugs, defective points, bad cables, or connections. 【300psi Dual Units Gauge with 3” Dial】: This compression gauge is easy to read with a range of 0 - 300 PSI and 0 - 20 kg/cm² dual units. The gauge cover is protected by an anti-scratch coating, and rubber protection absorbs shocks. All items are contained in an ABS case for easy storage, and the fittings accommodate most engines, making this a good kit for your garage. 【Easy and Safe to Use】: Start by removing the fuel pump and fuel-injection fuses, disconnecting the main wire to the coil and spark plug wires, and removing spark plugs. Then, thread the compression gauge into a spark plug hole by hand. Finally, turn the ignition on, depress the throttle, and crank the engine for four revolutions to obtain accurate data. Note: Ensure all parts are well installed before proceeding with the cylinder pressure test. Do NOT touch any part of the spark plug tester or test units when the ignition is on. Always switch off the engine and remove the key before handling.
