This spark plug is specifically noted for compatibility with Volvo Penta and Chrysler engines. However, it is crucial to verify the exact part number and specifications against your vehicle's requirements before purchase.
The NGK BUHX (2522) has a thread length of 12.7 mm, an outer thread of 14.0 mm, requires a 20.8 mm spanner size, and has a spark position of 0 mm.
Always consult your vehicle's owner's manual or a trusted parts lookup tool. Compare the specifications (thread size, reach, heat range, etc.) and the recommended part number for your engine.
Semi-surface discharge refers to the design of the spark plug's electrode, where the spark jumps slightly away from the main insulator body, which can help prevent flashover and fouling in certain conditions.
The NGK BUHX (2522) is a standard spark plug with a fixed gap designed for its specific application. Do not attempt to adjust the gap unless explicitly stated as adjustable by the manufacturer for that specific model.
Replacement intervals vary greatly depending on the vehicle manufacturer and the type of spark plug. Refer to your vehicle's maintenance schedule for recommended replacement intervals.
Verify the spark plug is the correct type for your vehicle and that it was installed correctly with the proper torque. Check for other ignition system issues like faulty wires or coils.
Ensure the spark plug is securely connected and that the engine is receiving adequate fuel. A worn or incorrect spark plug can contribute to starting problems.
A fouled or worn spark plug can lead to incomplete combustion. Check the spark plug condition and ensure it is gapped correctly if applicable (though this is a fixed gap plug). Consider if other engine components are affecting efficiency.
Compatibility Check: Before purchasing, always verify that the NGK BUHX (2522) spark plug is the correct part for your specific vehicle make, model, and year. Consult your vehicle's owner's manual or a reliable parts catalog to confirm compatibility. The key specifications to check are thread size (14.0 mm outer thread, 12.7 mm thread length), spanner size (20.8 mm), and spark position (0 mm).
Installation: Installation should be performed by a qualified mechanic or individual experienced with automotive maintenance. Ensure the engine is cool. Remove the old spark plug using the correct size wrench. Inspect the new spark plug for any damage before installation. Thread the new plug in by hand to avoid cross-threading, then tighten with a torque wrench to the manufacturer's specified torque setting. Use the 20.8 mm spanner size for tightening.
Care: Spark plugs are typically maintenance items and are replaced at scheduled intervals. There is no regular 'care' required for the spark plug itself once installed, other than ensuring it is properly torqued and sealed. Regular engine maintenance, including checking ignition system components, is recommended.
