A basic question for some of you. Are the 071 plugs ok to use on a 2wd cosworth running 13 psi? The car is currently got AGPR902P plugs fitted.

A FAR better plug to use at ths power level is AGPR12PP8, with a group a coil, way nicer, I have tried the ones you are using at the mo, then changed to the above and the difference is a LOT better all round.

Cheers tabetha,

Where is the best place to get them? I dont have a group A coil yet. Im off to the ring in the car soon and want to get the plugs changed before. Wont bother with a grp A coil untill after.

So the 071's better suited to a higher boosted engine?

Bruce

 

Never used the 071, so would not like to say.
My advice is change the coil first, you will not beleive the performance increase, especially low down.
I get most of my stuff where I can from MATT LEWIS 01922 692424.
I am using MAGNECOR leads, AGPR12PP8, group a coil, the coil made a world of difference, if anyone had told me how much difference I would not have believed them.

Magnecor is the best leads I've ever use on my cars!
I sales Magnecor around the Moscow Russia and all of my customers like this leads very much and after use some time one set they buying Magnecor on all their own cars.

 

A group A coil is money well spent, and they're cheap so go for it. I remember how pleased I was when my misfire disappeared when I fitted one

 

Does somebody knows what the resistance of the primary and the secondary windings of the grp A coil? Have it the resistance difference with the original coil?
I've got the dry coil but it 's not named grp A although looks absolutely like grp A coil.

 

The group a coil is just a BOG STANDARD LANCIA PART, or rather one for a lancia made by WEBCON.
There are loads of similar looking ones, but anything is much better tan the ford oe one which is only fit for the bin .

I bought the EPS 1.970.169. It's dry, with the similar resistance like std but has different the grp A plugs, looks like std coil plugs.

 

Sorry 2 but in but do the group A coils increase mpg to n how easy r they 2 fit. How do they cost arnt they about 50 quid

 

i dont know if they increase mpg, but they are dead easy to fit, pretty much a straight swap and i think i have seen them as cheap as £40 brand new

 

Hi there 071's will be fine very good plug for the money, quite widley used and reccomended by some top people as a good budget plug. As for a group A coil, I fitted one before I changed to wasted spark, cant say I noticed much difference either positive or negative but having said that I didnt have any problems with the std coil, as for plug leads the std beru leads are very good as long as there ok, if not I would go for the ford motorsport leads, available from lots of places, inc matt lewis msd etc.

 

Yeh, thanks for that information mate. That what i thought, sure a Group A coild is a good improvment over a dodgy standard one. As i have problems with my standard coil i will leave it.

Bruce

 

I'm getting lost not with all this talk about group A coils, could some one tell me what the 071 plugs are please (are they champion) I need a new set in my 2wd as its holding back when i high revs its a std 2wd engine runnig 360 degree T3 at 24 psi on greens, and i already have a group A coil,

Also it needs an oil and filter change does any one know the motorcraft part number for the oil filter and what oil should i use???

Sorry i'm changing then subject from spark plugs now but any help would be great. I wanna get my cossie back on the road.

 

The 071's are a motorcraft plug you get from ford. Mine were £12 for the four. I think they were fitted standard in the RS turbo engine.

Seem like a good plug. I gaped mine at 0.8mm.

Finis Number are 1120834

As for oil filter ask at ford again they will have them. I used silkolene pro S 10/50. I bought it from opie oils. His username is oilman on here. Seems like good stuff and i have only heard good things from guys on here and the guy who tuned mine.
