NGK 95897 Spark Plug

NGK Standard Spark Plug 95897 Overview

NGK Standard Spark Plug 95897 is a copper-core, nickel-tipped spark plug built for steady ignition performance in everyday driving. It uses a 5,000 ohm resistor, a standard ground electrode design, and a .032 pre-gap to support reliable spark delivery in the correct application.

As part of the NGK Standard Spark Plug line, this plug reflects NGK’s long OE supply background and focus on original-equipment-style durability for domestic and import vehicles. The 95897 spark plug is a practical choice for drivers servicing ignition systems on vehicles such as Honda Civic and Toyota Corolla applications where the specified heat range and thread dimensions match the engine requirements.

Detailed Description

NGK 95897 is a standard spark plug engineered around common OE-style dimensions and materials. The copper core helps conduct heat efficiently, while the nickel electrode design supports consistent firing characteristics in the correct engine setup. With a flat seat, 10.00 mm thread diameter, .75 reach, and 5/8 hex, this plug is specified for engines that call for those exact measurements. If you are replacing worn plugs on a Honda Civic or Toyota Corolla, confirming the original plug specification is the key step before installation.

This part cross-references Champion Spark Plug 349 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire conditions tied to degraded electrode wear
• Reduced throttle response from weak ignition performance
• Maintenance replacement for specified Honda Civic and Toyota Corolla ignition service

Installation Notes and Tips

Verify the engine’s required thread diameter, reach, seat type, and heat range before installation. Check the existing plug gap against the vehicle specification and confirm the terminal style matches the ignition lead or coil connection. For best results, install only in applications that call for the NGK MR7F / 95897 specification, and inspect the ignition system for carbon tracking, oil fouling, or damaged boots during service.
