rang too different well know tuners

1 said for for champion C57c plugs for my RST (16psi)

the other said C59c

which one is correct?

 

NGK BCR8ES

 

nope bin told there a load of poo poo davie, especially if running 16psi

 

What about Ford Motorcraft Super spark plugs? Rated or not?

 

aint nothing wrong with NGK BCR8ES

 

Naff all wrong with ngk's i had them in my old s2 running 18 psi.

 

Everyone seems to have different views on this topic....I was told by a well respected tuner to use big turbo escort cossie plugs, pp8's i think they are.....ain't had no probs with em, good for big boost as well! Got em from Ford, pricey tho!

 

16 PSI is nothing.

 

Thats all im running

 

59c for anything over 14 psi

the other for up to 14 psi , its what ive used on 4 turbos , no problems whatso ever , i dont think theres a best spark plug either

 

071s £2.20 each from ford

 

So whats wrong with using NGK BCR8ES at 16psi

 

dunno davie just going by what MSD told me yesterday on the phone

so c59c will do then?

alex what you find the life of the ford o71s are like?

cos they pretty cheap!

 

Nothing, because 16 PSI is not extreme boost. The plugs you would have gotten at Ford would have done the job. Buy NGK BCR8ES cheaper than 57/59c and good enough or just as good.

 

think i mite just go for the ford jobbies then, unless them NGKs are a better option

 

Agreed


Myself and Mr C run these plugs with no problems at 2 bar of boost and 300+ bhp. Need we say anymore?

 

well thats that sorted then ford ones it is! cheers lads

 

NGK BCR8ES plugs are fine mate and are only £7.99 fo 4 at halfords

 

im usin the ford plugs at 21psi with a gap of o.65, dont have any probs, change them every 3-4 k.

gunna get a group a coil and open the gaps up a bit hopefully
