What plugs do you folks run in your YB's ??

Any info greatly appreciated

 

i run 071C's in mine

 

Cheers Simon.

Anyone else?

 

For my stage 1 I run AGPR12PP8, way way better in mine that any other.
tabetha

 

Same here.

 

The AGPR12PP8 are std 4x4 yb plugs not had much in the way of testing on over standard yb's not a dis Tab !

The 071C's are also a std motorcraft plug but tested and reliable @ 400hp plus with no side affects then the next step IMHO would be denso irridiums but for value reliability and stats speaking for them self 071C's all day long .

BCR8Es or denso IK27s

 

I asked basically the same question a week or so ago, and Stu(mr msd) said the agpr12pps'
that i had were pretty much the best plugs available for stg1 applications.........
good enough reason to fit them for me!!!

Don't know about higher up the power levels though...

 

Jam needs plugs for 500 bhp

 

I did kinda realise that euan, what wi the 8 greens an that.....

Was just commenting on a reply from earlier.


Always good to know what plugs you big power blokes recommend,
'cause you never know when the info could come in handy!!

 

Its Jams fault Jake...he needs to be clearer in his questions

 

Don't know why he didn't just ask you anyway.......

Get the info 1st hand!!!!!

 

Hence why I said I have not had much in the way of testing above std yes I agree with Stu they are fine IMHO for low horse power and low boost out puts the same as AGPR902pp are also a good plug but for high power high boost I would reconmend the 071's or irridiums thats my prefference on experience on my own cars .

bcr8es £2 a plug on mine

i fitted £60odd quid iridium hks things just for it to have a missfire on the rollers

 

pretty much the same as me..

the densos were good but always had a tiny miss at a certain point of the rev range that is now cured after fitting the BCR8es

 

bcr8es,,whare can i get them online?

 

I have used PP8`s and found them fine till 380 bhp, i now use champion QC57C race plugs (@ 450 bhp ) found them to be a bit poor when the engine is cold but fine when hot.. out lasted all the others for reliability..

 

Alan at AVA keeps them in stock mate

 

Champion QC57C's or 071's, never had any problems with either.

 

i currently have pp8 in small turbo gapped to 0.7. Im going to be changing these to pp12 and gapping to 0.85 as it currently has a splutter and slight miss on the pp8. Hope this will cure the splutter up a bit as have rolling road day on 28th too

 

Thanks for all the info guys.

I should of been more clear at the start as to what i was after. Sorry bout that.

Anyway your info has helped loads. Thanks again

 

just get Alan to do the plugs when he maps it
