SPARK PLUGS
Twin electrode plugs are recommended due to the Wasted Spark ignition system used on the 1JZ-GTE engine.
Platinum (or other precious metal) spark plugs do not necessarily perform any better nor last any longer than
standard copper plugs.
• Recommended: NGK BKR6EK (twin electrode copper plugs ~$8ea)
• Platinum: NGK BKR6EKPB-11 (twin electr ode ‘Premium Platinum, Spe cial Design’ s park plugs ~$20ea)
• Alternatives: NGK BKR6E, NGK BKR6E-11, NGK BKR7E, or NGK BKR7E-11
Notes: The -11 designation of the above NGK brand spark plugs denotes that the plugs are
factory pre-gapped to 1.1mm. The non -11 designated plugs are exactly the same except that they are
not factory pre-gapped to 1.1mm, however, I’m jet to find a set of non factory pre-gapped plugs to be
anything other than 1 .1mm!
SPARK PLUG GA P
The recommended spark plug gap for a stock 1JZ-GTE engine is 1.1mm.
As you increase boost in a BPU applicat ion, you should cons ider progres sively reducing t he gap on your spark pl ugs,
starting with the largest gap, until such a point that any ignition issues are negated (i.e. misfire, rough idle etc)
Also, before redu cing the plug g ap too much, consider changing to a colder heat range plug first w hile s tarting with
the recommended stock 1.1mm plug gap. Only reduce the spark plug gap if problems persist.
