Hi guys going to put new plugs in my saff 4x4 cossie running 330 bhp, currently has agpr12pp8 in just wondering what you would use

 

Mine is only running stage one, but it kept blowing no1 spark plug with NGKs, so I changed to PJ Motorsports Ł25 set, no problems at all since then, hope this helps.

 

Motorcraft 071 plugs m8 finis code 1120834.

 

as above or champion c59s

 

yeah get the motorcraft ones mate.... easy on the Ł they are actually Denso I think so just sold in a motorcraft box! Everyone's happy

 

About the same stage as you, but i use it only on track, so some cold apgr701c's gapped @ 0,65mm for me

Do u ru n these plugs gapped down kev ???

 

I do...

On my old stage 3 they were gapped down due to the boost blowing out the spark

 

NGK 9,S IF YOU COULD STILL GET THEM


cheeRS stu

 

were they gapped down quite far ??

are these the plugs thats listed for escort cossies ,heard a lot of peeps mention that before on the 2wd saffs ??

I have the ngk irridium (spellin ) plugs but they did cost me near Ł60 odd quid thereabouts and have been fine so far but are exspensive for how a cossie a can eat plugs lol

 

.25 or something rings a bell? Not quite sure from memory. I was running about 28psi boost

new plugs about every 2000 miles though. At least they were cheap!

 

Sure do and they're perfect mr mills.

 

0.65 for me.

 

Thanks mucho

 

Very welcomeo.

 

Cheers guys thanks for the replies, are the pp8's not any good then ?

 

Hi guys have just fitted QC57C plugs on recommendation but was told to expect lumpy tickover is this true and has anyone else had this ?

 

yes there race plugs m8 you will get a bit of a lumpy tick over

 

Its a very good plug mate so if you can put up with the lumpy start its worth it, alot of people go for c59`s but i`ve been told that there not that good for a 330/350 brake cossie, more a 220 brake rst engine kind of plug

 

Have used pp8's for years and no problems gapped at 0.6mm

Run same gap and plugs on greys at 30 psi never missed a beat

 

i got Denso iridiums in mine, runs sweeeeet

 

Same here.

 

I use 57's in my 200bhp rst aswell.

Use platinum tipped Motorcraft PP8's in my cossie, running similar spec as you.

 

just popped some new ones in my m8s standard 4wd just gapped em at 1mm like ford say. Thats gotta be right for std power, right????

 

How much should I pay for motorcraft 071's?
Can't find a price anyone know????

 

I paid Ł10 for 4.

 

Cheers me old
