NGK/Iridium/BKR7EIX/WRX/one step colder have just been bought.

i put them in the car out the packet and the car is rough!!!!

I am going to space them tomorrow- whats is the best gap to make them?

I am running EJ20 on newage car
Cheers

 

i do believe its 0.7, but my memory isn't that good

someone will be along to confirm i'm sure.

Aaron

 

I think i gaped mine at 0.7.

 

0.7 rings a bell lads!! cheers

II didnt check them and installed them straight in, would there be a good chance if I bought them off the net that they would not be gapped correctly?
Car was jumping about terribly....really bad idle
Cheers

 

Deffinately check them mate.

Aaron

 

cheers-is that 0.7mm?

 

yep

 

cheers- so it should not be tight in the gap but a little friction moving the gauge in between?
Any preferred ways to actually do the gapping?
Cheers

 

what is the stock gap lads on the standard spark plugs for a wrx ngk 6b?

 

was it 0.7 as well?

 

anybody- thanks

 

have ordered a set of these from as performance, think i better check mine before i put them in i think, just to be on the safe side

 

mate defo
So stock and one step colder spark plugs both gapped to 0.7mm?

 

std0.8?

 

So guys for NGK heat range 7 plugs I need to go to 0.7mm?
Is everybody the same or has anyone used different gapping?

Cheers

 

please- SP going into car tomorrow

 

get them gapped to 0.7 if your still in doubt give Duncan a quick phone in the morning at hypertech he will keep you right greig

 

cheers!

 

Anybody went different to 0.7 on these spark plugs

 

I read on NASOIC the gap should be :
02-03 WRX plug gap range is between 0.28 - 0.31 ?

Is this wrong then?
Im confused!

 

seems very small got a link to the thread see what folks have posted on it what did Duncan say? di you have them out today if so what gaps were they?

Greig

 

Hey mate yeah put them in initially and the stutter was terrible mate!
I then took them out and there wasnt a lot in it but they did need regapped a little.
I put them to 0.7mm and it was generally ok but still was stuttering a little between 2 and 3 k revs.
Idle was better but still not perfect mate
I recently removed egt sensor and fitted up pipe decat and td05 16g turbo- wondering if this is the cause prior to remap?
Also snapped boost vacuum lines which i replaced with bigger diameter vacuum and no restrictor pill currently
here is the link mate One Step Colder Spark Plugs? [Archive] - NASIOC

I have a BKR7EIX is one step colder

Cheers!

 

oh cheers for the resistor-didnt realise it was you bud!!
The light is still on but not flashing now

 

I didnt phone duncan mate as he is supposed to be putting the spark plugs in for me- I might have to phone him though if no one else is sure of gap

 

THATS INCHES MATE!! LOL
IGNORE ME!!
Still not sure why car is running rough though
Might need to pop up to you at some point if you can get a hold of that plug in reader thingy to see what its showing

 

Aye thats cool mate im nightshift now but at the weekend or the week after im free ppm me when you want to nip up and we can try it out ill check the book see if it works on your car.

The remap wi Andy should sort all the roughness out but make sure you get those boost hoses changed so they are the right sizes and so on Andy will keep you right on the day and is very quick at picking up whats not right

Send him an email the now and ask him what he thinks before you go he might get you to try changing a lil something Grieg

 

cheers mate!!!!!!!!!!
Aye next week tuesday evening onwards would be ideal mate.
Ill give you a text on sunday regarding it!
Cheers!

 

spot on bud . Grieg

 

Sorted mate!!
Ill have to pop up and see you with it some time
Turns out one of the spark plugs i had put in had a crack on it!!
Replaced with old spark plugs and all is good - no light!!
Phew!!
Running ok again as well!!
Cheers for your help

 

PFR7B the same spark plug exactly as BKR7EIX in the NGK IRIDIUM range?

Cheers
