O.K I posted a few days ago that I used a thick rubber hose for an oil return line...anyway the line hit the manifold and burned a hole...so now I changed it to a steel braided line (which I know I should of done in the first place.. ) I also changed the spark plugs from ZFR5F11 to ZFR6F11. Anyhow the car is NOT pulling like it was...I'm so pissed did I use the wrong plugs? or is it something else? (SOHC,Greddy turbo kit, missing link no black box, Vortech FMU) Any help would be appreciated...

 

hey you should check and make sure the oil is not clog at the oil return..... im not sure if that matters..as far as the spark plugs i didnt replace mine yet... i have a 00ex and used greddy kit. i just finished my install 2 days ago.... late

 

what are they gapped at?

 

gapped at 31? are those the right plugs to use? Another guy I talked to used the NGKZFR6J-11

 

try gapping them at 28. And use 11 plugs. Such as BCP7'-11S or BKRE7-11,

 

Are these types both NGK?

11 just means theyre pregapped from NGK
thats all (1.1mm)

but youre going to change he gap anyway
so it really doesnt matter...
