NGK V-Power UR5 Spark Plug Set (8) — Nickel Core, 0.040in Gap, OEM-Style Replacements

NGK V-Power UR5 spark plug set (8 pieces) are OEM-quality nickel-tip plugs with a 0.040-inch gap designed as direct replacements for compatible engines.

These NGK UR5 spark plugs come as a bulk-packed set of eight, each built to NGK's factory specifications for fit and function. They are intended as direct replacement parts (stock 2771) for vehicles that call for the UR5 electrode configuration and 0.040-inch spark gap; installation should follow the vehicle manufacturer’s torque and gap recommendations. This product listing focuses on the basics a buyer needs to confirm compatibility and to understand the physical features and packaging of the plugs.

How do these NGK UR5 plugs match original equipment?

The UR5 plugs are manufactured by NGK to meet OEM dimensions and electrical characteristics used by many vehicle makers. That means they are intended to fit and perform like the original spark plug specified for engines that list stock 2771 or UR5 specifications.

• OEM-style nickel core tip for standard ignition systems
• Pre-set 0.040-inch electrode gap for typical stock applications
• Thread size and seat designed to match original factory parts
• Sold as a set of eight for multi-cylinder engines or full-plug servicing

What does the nickel core tip and 0.040in gap mean for compatibility?

A nickel core tip is a conventional electrode material suitable for many standard ignition systems; the 0.040-inch gap is a common factory gap for numerous engines. Together these specifications indicate the plug is a standard replacement rather than a specialty long-life or high-performance option.

• Nickel core: standard conductivity and wear characteristics
• 0.040in gap: ready for many stock ignition calibrations
• Not an iridium/platinum performance plug—matches OEM expectations
• Check vehicle manual to confirm UR5 or stock 2771 compatibility

How should I install and torque these NGK replacement plugs?

Installation should follow the vehicle manufacturer's service manual: clean the threads, hand-start the plug to avoid cross-threading, and then tighten to the recommended torque. If a torque wrench isn’t available, use the factory-specified method (e.g., finger-tight plus a fraction-turn) to avoid damage to the cylinder head or seal.

• Inspect and clean plug holes before fitting
• Hand-start each plug, then torque to the vehicle spec
• Confirm the 0.040in gap if re-gapping is needed for your engine
• Replace boots/wires as needed for best ignition performance

What should I check for vehicle fitment and ordering?

Always cross-reference the UR5 or stock 2771 part number with your vehicle’s parts list or owner’s manual before ordering. Many parts databases and dealership parts departments can confirm whether UR5 is the correct plug for your engine variant and model year.

• Compare NGK UR5 / stock 2771 with your vehicle’s required plug number
• Use VIN or engine code when contacting parts suppliers for accuracy
• Confirm you need a pack of eight (number of cylinders) before purchase
• Bulk-packed items are new but may lack individual retail boxes

Who is this for: This set is appropriate for DIY mechanics, repair shops, and fleet maintenance teams that require a direct OEM-style replacement in quantities of eight—for example, full-service on V8 or other eight-cylinder engines. It’s best for users who want reliable, standard-spec NGK spark plugs rather than extended-life or high-performance electrodes; buyers should verify UR5 (stock 2771) compatibility in their vehicle documentation before purchase.
