As above AGAIN need to get a set for the trip down to national day , running 22psi

 

C57 25 thou

 

id go for the 071 as i had problems when i used 57s and 59s in my last cossie

 

Im now running the 071's as well...with no probs Tried the champions in the past and found that they died after 1500miles....found the pp8's were spot on but got worried about them killing my engine...hence the swop to 071. Been in for about 2500 miles now with out fault

 

071.....good on idle also...the champions doesnt..

 

Go for the 071's rab, 0.6mm gap.

 

what gap do they come with "out of the box" ?

 

Where do you get them kev? and whats the full part number mate?

 

finis code 1120834

from ford

 

Thats ma bhoy

 

Beat me too it !!

 

Hey guys, living over here in New Zealand is hard for sourcing parts.

Are these plugs made by Motorcraft and is there full name 071's ?.

Obviously having the finis code is a huge help but some of the parts guys at ford over here aren't too smart so it's always good to have there full name and exactly who manufactures them

ps. I use Motorcraft AGPR 12PP8's in my Stage 2 (soon to be 3) Sapphire running 18psi of boost, is this a good plug to use or am I likely to melt a piston or something?

Cheers guys

 

@snow..stage 3 and 18psi...what turbo do you have...

 

Just edited my post mate , it was 6am New Zealand time when I wrote that I've had my coffee now

 

They're motorcraft plugs m8,AGPS 071C standard fitment plug for series 1 turbo.

 

Thanks alot KSA-Cossie
So they'd be the best bet for my Stage 2(soon to be 3) Sapphire mate?

 

Yeah m8 stu at MD advises them.

 

Yeah and they only Ł2.39ea, unfortunately my local friendly Ford dealer will only VOR them and in boxes of 10!

Anyway, if they come highly recommended then must be good

Cheers guys

 

My local dealer can get them in 4's if anyone needs em.

 

I know i had to buy a box of ten no one had them and they wouldn`t send 4 so they cost me Ł28 hope there worth it , motocraft super it says on the blug , with blue rings round it is this right ?

 

id use c57 m8 gapd at 25thou

 

 

When you upgrade get rid of them PP8's as they are bad news. Things will melt bigtime...........

The 071's which are mentioned in this thread are spot on

 

Cheers Smit, I'll give Ford a call tomorrow and have them order some in for me from the U.K

 

will these run a treat on my stage 1 cosworth? my car is a daily driver and dont get ragg'd all the time

 

my vote:

Motorcraft 071's

 

I run them and mine is stage 3'd m8.

 

right got mine in and noticed a difference in the mornin as it was a bit cold, it held strong revs when letting off thrrottle and didnt dipp below 500rpm, much better imo than the pp8

 

 

NGK 9'S BUT NO LONGER AVALABLE DONT KNOW WHAT TO USE NEXT,AS RUNNING 30 PSI OF BOOST AND 470 BHP

CHEERS STU

 

071s for me

used c59s for two years then blew the engine and have been using 071s ever since. Cant complain and they are cheap too

 

So what can everybody agree is a good gap to have with the 071 spark plugs?.

I have some on order but I'd love to know what to gap them to?.

Cheers!

 

0.7 mm.

 

mines are .6 is this maybe why my revs on idle are sometimes up and down

 

Mine are at 0.6, and idle is a bit up and down especially when cold, so I tried at 0.7 idles better but cuts out above 20psi, so I have gone back to 0.6. I would like to solve this but do not know what plugs to try. I have a group A coil as well so voltage must be good

 

i may do that with mine daz, 0.7 as my car is only stage one

 

that's true, but it's better on high revs...

I've talked to a man that prepared cossies for rallying...he said that 0.55-0.6 the best is for a cossie with 300-380bhp, and he has also worked for Ford Motorsport...so i'll trust that man

 

*Bump*
Sorry to bump this thread guys, but I'm going to gap my new 071 plugs this week and before I do I was wondering if any of you chaps in the posts above me had changed their 071 plug gap?.
Obviously there was a bit of talk between 0.55mm-0.60mm and also 0.70mm

From what I can gather by what you guys have posted, 0.70mm will give you a smoother idle but may be a little lumpy higer up the rev range.

And 0.55mm-0.66mm will be sleightly rougher on idle but perform better higer up the rev range.

Just curious as to what might have developed with you guys altering your gap and if anyone has some good info that would be helpfull.What is a better trade off too, smoother top end and rougher at idle or the other way around?.Form what I hear it's pretty common for a Sierra to be a little rough on idle?.
My Sapphire is just a touch over 300HP, running 18 PSI of boost, with, Green 803s,-31, 3 Bar, RS500 Spec Intercooler,Mongoose Exhaust, Bailey Breather System, Standard Turbo.
Lastly, what gap do the Motorcraft 071s come with as standard?.

Cheers guys

 

With your boost i'd say 0.7mm m8,will give you a good idle too.

 

In france, we are using BOSCH F3CS, anybody test it ???
