had a look on thier site, and they suggest the following.....


SIERRA 2 RS 500 Cosworth 162 YBD (T31/T04) 05.87-'88, K27PR-ZU, IK27, VK27PR-Z11.

OR

SIERRA 2 RS Cosworth 150 N5A (YBB) (T03) 10.85-'89, K24PR-ZU, IK24, VK24PR-Z11.

Also, whats the difference between the power, and the "tough" ones?

Cheers

no idea on iridium plugs, but I hav been using 071s and they are good plug.

 

think everyone uses 071's now

 

071 s 6 pounds from ford

 

I have IK27's in my engine, but it appears that IK31's are the way forward, the 27's seem to be a bit cold under heavy load conditions (having had problems with them myself), whereas the IK31's hold steady all the way with no problems

 

My iridium plugs just fooked up on my RS!

I got a set of 701's in mine now Your be hard pushed to find some of thme tho

 

ive got pp8's in it at the moment, and was just wondering what everyone used.

 

Just fitted a set of IK31's last night

 

i've got standared ngk plugs and they work fine
running 28lbs of boost and no problems

 

lordy lordy!

RING YOUR FKIN TUNER!

 

think it might be IK27 in mine but not sure??

 

what is meant by a plug being cold, as Karl put a set of Densos in mine and said they are quite a cold plug

 

i txt him but no reply

 

i think karl likes the champions 57 59s

 

think i have ik27 in mine now,no problems up to now.

 

c57'c's,about a 30 thou plug gap..............................

using msd digital 6 ignition system,fires anything!

puddy

ps. colder/harder plug= short central electrode.

hotter,softer plug=longer centre electrode.
