VR38 NGK Race Plug

The NGK race plugs are what we use and recommend for over 2000hp in the VR38.  We offer both 9 and 10 heat ranges, which is one or two steps colder than the stock plugs.  We recommend heat range 9 for cars making up to 1,600whp using gas or ethanol fuels, and heat range 10 for anything over that running ethanol or methanol.

Price is per plug.
