NGK 6994 Spark Plug

NGK Laser Iridium Spark Plug 6994

NGK 6994 is a Laser Iridium spark plug built to OE specifications for select Honda and Acura applications. It uses an iridium center electrode, nickel ground electrode, and a 0.044 in pre-gap to support consistent ignition performance in engines that call for this exact setup.

Laser Iridium Design

The NGK Laser Iridium Spark Plug line is engineered around precise OE-style fitment and durable electrode materials. For this part, the iridium center tip, copper core, and trapezoid ground electrode design work with a flat seat, 14 mm thread diameter, 0.75 in reach, and 5/8 in hex size. The 5000 ohm resistance and non-removable nut terminal match the listed OE-style configuration for the applications shown.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Misfire conditions tied to incorrect gap or electrode wear
• Rough idle and inconsistent combustion in OE-spec engines
• Reduced throttle response from aging ignition components
• Service replacement needs for Honda Civic, Accord, CR-V, and Acura TL applications

Installation Notes

Verify the engine calls for a 0.044 in gap and confirm the listed thread diameter, reach, seat type, and hex size before installation. Use the vehicle service procedure for torque and plug access, and inspect the ignition system for wear if the original plugs show heavy deposits or damage. This part cross-references DENSO Auto Parts (e.g., 4504, 5615) for the same application.
