put it in nzr as its not for a zed as such. i was wondering the benifits of running cold plugs is it a nessicary when upping the boost??? any input appreciated. im gonna up the power on me 200 an sxoc has so many differing opinions :confused: :confused: lol

less chance of running lean and on top of that peace of mind when upping boost

 

i used the next stage on my s14a ngk iridium x7s or something like that. Car drove like a rat up a drainpipe with 1 bar of boost and straight through systym, if the cats are still on your car get rid of them, the differance is amazing, i miss my sx and my zx LMAO

i got walbro now mushroom filter nur spec r full system decat its boosting at 10psi atm. i wanna get sus an brakes done an plugs before i up the boost i want all the saftey aspects to be there first thinkng of type 2 fmic also

Kins i put new front pads on few months ago just to let you know. Colder plugs would help tho. What you putting boost to?
