My car a '94 Acura Integra GSR, JRSC with the steeper pulley from Endyn (~8 psi), RC 310 injectors, aem fuel rail, lower compresion, etc.

I like to know recomendations about spark plugs, brand, model, temp, etc. (Beru, Denso, NGK, etc.)

I know that a person from this forum have a GSR with a 12 psi JRSC, I like to know what spark plugs he use (brand, model, temp, etc.).

Thanks in advance,

Dariusz

 

Try the ZEX spark plugs. They are 2 heat ranges colder than stock. I use them in my Vortech SC'ed GSR.

 

Bosch Platnuim F6DP or NGK R ZFR6F - Ive had good results with both these plugs. I tuned with the NGK's because they are easier to read - then switched to the Platniums.....
94GSR JRSC @9psi

 

Just for reference, the 2 plugs above are 1 heat range colder.

 

Get NGK part # 1095. They are BCP7E(something like that) -11

 

I use Ngk BKR 7e ,gapped to .035 in my Si...These are the split groove plugs...JRSC at 8 psi....
