Honda J35A4 turbo engine, what spark plug?

[JM PRO]

What spark plugs do I run on a Honda 3.5 engine with 8 pounds of boost? Engine is stock internals.

Thanks

-2 or 3 colder plug

Halferland sells them, but I'm sure you can get them elsewhere too.

I am using the NGK BKR7E gapped to .022

I'm also on the BKR7E, 10psi. pump gas. this is what Xact Dyno recommended.

Huh.  BKR7E is the Nissan boosted plug of choice too.  Available at just about any auto parts store.

Perfect. Plugs ordered. The factory gap is suppose to be .044", is .022" the correct revised gapping?

Yep.  0.044" is good for emissions and fuel economy.  Need the closed gap so the extra cylinder pressure/fuel doesn't blow the spark out.

Makes sense. Thanks
