NGK Factory Replacement Spark Plugs

NGK is the original manufacture for the NSX spark plugs. Exact replacements are available at a fraction of the price from Honda (which cost $114.00 for the set).

ScienceofSpeed offers two types of spark plugs:

Laser Platinum - these are the factory specified plug. Honda recommends replacement every 60k miles or sooner. This is the plug we recommend for 99% of our customers.

ScienceofSpeed also offers the NSX-R spec spark plug which uses a one step colder heat range of 7. This plug is recommended for engines producing high cylinder temperatures due to extended high RPM and wide open throttle use. We recommend this plug for use in NSX used on the track. This plug is not recommended for a "daily driven street car" application where the engine is not at constant high RPM use due to plug fouling that may occur.

These plugs are pre-gapped at .043". Do not adjust gap out of box or damage will occur.
Iridium IX - Iridium plugs offer increased electrical efficiency with a narrower iridium type electrode.

The primary benefit of this plug is is thermal resistance making it ideal for high horsepower supercharged or turbocharged applications which experience high cylinder temperatures. We recommend a heat range of 7 for most forced induction applications. We recommend inspection / replacement at 30k miles.

These plugs are pre-gapped at .043". Do not adjust gap out of box or damage will occur.

The spark plugs are sold each. 6 plugs are required for the NSX.
