About this product

NGK spark plug (6597) fires the air-fuel charge with a precisely controlled spark at the correct electrode gap and heat range for your engine's combustion chamber geometry. Plug parameters — Thread Size: M14 x 1, 25, Spanner Size: 20, 8 mm, Spark Plug: 55, Spark Plug: 52 — determine ignition timing accuracy, electrode longevity, and resistance to pre-ignition deposits across the full RPM range. Thread reach, seat type, and hex size are specified to fit ARO, ASIA MOTORS, AUDI, BMW and 30 other makes cylinder heads without re-gapping or thread chasing. Replaces OE ignition references: 0000-18-8914, 0000-18-B601, 0 001 325 701, 0 001 325 704 and 567 more. NGK ignition components are manufactured to SAE and DIN specifications and are approved for use in vehicles covered by manufacturer service agreements throughout Europe. Standard copper-core spark plugs last around 20,000–30,000 miles, while iridium or platinum-tipped plugs can last 60,000–100,000 miles — always follow the interval specified in your vehicle's service schedule. Symptoms of worn spark plugs include rough idling, engine misfires (often felt as a stumble under acceleration), increased fuel consumption, and difficulty starting in cold weather. Spark plug replacement is a straightforward DIY job on most engines — you need a spark plug socket, a torque wrench, and a gap gauge; allow 30–60 minutes for a four-cylinder engine, longer for boxer or V-configurations where access is tighter. Always match the heat range and electrode material specified by your engine manufacturer — fitting a plug with the wrong heat range can cause pre-ignition, fouling, or catalytic converter damage. Replacing spark plugs on schedule maintains optimal combustion efficiency, reduces harmful emissions, and prevents unburnt fuel from damaging the catalytic converter — a component that costs many times more to replace. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.

What specifications does this NGK Spark Plug have?

This NGK Spark Plug has the following specifications: Thread Size: M14 x 1,25; Spanner Size: 20,8 mm; Spark Plug: 55; Spark Plug: 52; Spark Plug: 28; Spark Plug: 11. Check the full specifications table above for complete details.

What OE part numbers does this Spark Plug replace?

This Spark Plug replaces OE part numbers: 0000-18-8914, 0000-18-B601, 002 159 22 03, 002 159 29 03, 002 159 31 03, 002 159 48 03, 003 159 10 03, 003 159 11 03 and 229 more. Cross-reference these numbers with your vehicle's original part number to confirm compatibility.

How much does a Spark Plug cost?

This NGK Spark Plug is available for £16.99. Spark Plug prices vary depending on brand, specifications, and vehicle compatibility. NGK parts offer a balance of quality and value, backed by our 14-day money-back guarantee.

How do I know when to replace my Spark Plug?

Signs include rough idling, difficulty starting, engine misfires, increased fuel consumption, or lack of acceleration. Most spark plugs should be replaced every 30,000-60,000 miles for copper, or 60,000-100,000 miles for iridium/platinum.

What tools do I need to replace a Spark Plug?

Tools needed: spark plug socket (16mm or 21mm, with rubber insert), torque wrench (20-30 Nm typical -- check vehicle spec), ratchet with 3-inch extension, feeler gauge for gap check, anti-seize compound. Difficulty: Moderate DIY. Safety warning: Allow the engine to cool fully before removing plugs. Over-torquing will strip aluminium cylinder head threads -- always use a torque wrench.

Can I use this part as a replacement for OE 0000-18-8914?

Yes, this NGK Spark Plug is a direct replacement for OE part number 0000-18-8914. It is manufactured to meet or exceed original equipment specifications, ensuring proper fitment and performance. All cross-reference data is verified through TecDoc.

Is the NGK 6597 the same as the NGK 0005?

No, while both are Spark Plug parts, they are different products. The NGK 6597 has Thread Size: M14 x 1,25, Spanner Size: 20,8 mm, Spark Plug: 55. The NGK 0005 may differ in dimensions, fitting position, or material composition. Always verify compatibility with your specific vehicle using our vehicle selector, or contact our customer service team for assistance.
