4AGZE Sparkplugs

[craigy]

Hey Guys,

I'm in the process of installing a GZE in an AE86 and i'm in the final stages of preparing my engine to be slotted into its rightful locale.

I want to replace the spark plugs with a good set keeping in mind that the car will need to be tuned with an aftermarket computer running 14psi.

Just wondering what type plugs people are using and what gaps?

cheers

Denso PQ20R is what ive always used in the ZE

just use plain old ngk till its tuned! that way if you foul them you can throw another set at it! not much in plugs now days!

NGK BCPR6ES gapped to 0.8mm should do the job, much more boost & you might want to go for 1 heat range cooler (ie. BCPR7ES).

I started off with 6ES in mine (big NEVO pulley), and they looked far too shiny and clean when I inspected them. I went to 7ES and everything has been good since.

i've been useing the V-groove NGK's on all my 4ag variants. BCPR6EY (Y= v-groove) gapped at 0.8mm for the 4agze and gte (though i do have 7's in the gte at the moment).
