This NGK Spark Plug (90738) is designed for vehicle owners seeking reliable ignition performance, offering enhanced durability with its iridium middle electrode. While it provides a precise 0.8mm electrode gap for optimal combustion, it's crucial to verify vehicle compatibility before purchase to ensure proper fitment and function. This guide covers its features, installation, and maintenance.

You must cross-reference the NGK part number (90738) and the specified Ford part numbers (2249264, HX7G12405AA) with your vehicle's owner's manual or a reliable automotive parts catalog. This spark plug is listed as fitting FORD Fiesta Mk7 Hatchback and Puma SUV.
The electrode gap is the distance between the center electrode and the ground electrode. A 0.8 mm gap is precisely engineered for optimal spark energy, leading to efficient combustion, better fuel economy, and reduced emissions for compatible engines.
Replacement intervals vary by vehicle and spark plug type. Consult your vehicle's owner's manual for the recommended service schedule for your specific model. Iridium spark plugs generally have a longer lifespan than standard copper plugs.
While possible for experienced individuals, incorrect installation can lead to engine damage. It's recommended to have spark plugs installed by a qualified mechanic who can ensure proper torque and connection.
Iridium is an extremely durable metal, allowing for a smaller, more focused electrode tip. This provides a stronger spark, better ignitability, and significantly longer service life compared to conventional spark plug materials.
The spanner size required for the NGK Spark Plug DILTR6A8G - 90738 is 16 mm.
Ensure the spark plug is correctly installed, the gap is set to 0.8 mm (if adjustable, though this model typically comes pre-gapped), and the spark plug wire is securely connected. If the issue persists, the spark plug may be faulty or the vehicle may have other ignition system problems.
Worn spark plugs can lead to inefficient combustion. Ensure the spark plugs are the correct type for your vehicle and have not exceeded their service life. Replace if they are old or show signs of wear.
Check that all spark plugs are correctly installed and the ignition system is functioning. Multiple faulty spark plugs or a broader ignition issue could cause starting problems.
Compatibility Check: Before installation, *always* verify that the NGK Spark Plug DILTR6A8G - 90738 is the correct replacement for your specific vehicle's make, model, and year. Consult your vehicle's owner's manual or a trusted automotive parts database. Check that the listed compatible Ford part numbers (2249264, HX7G12405AA) match your vehicle's requirements.
Installation: Spark plugs should be installed by a qualified mechanic. Over-tightening can damage the cylinder head, while under-tightening can lead to poor sealing and performance issues. Use a torque wrench to tighten the spark plug to the manufacturer's specified torque.
Care: Spark plugs are not user-serviceable items for cleaning or adjustment in modern vehicles. They are designed to be replaced at recommended service intervals. Regular engine maintenance, including checking ignition system components, is advised.
