My car has been missfiring so ive taken all the sparkplugs out and they seem to be ok, what plugs would you reccomend in their place?

Could be a bad conection on a coil pack.

Or inbetween the coil pack and spark plug!! which can happen!

Missfire usually caused by coilpack failure, coilpack connector, PTU, PTU harness. CAS, Injector or injector connector.

 

what plugs were in there ? You want NGK PFR6B-11B

I have NGK IR IFR6J11

I have NGK IR IFR6J11

Dunno what they are mate, but no plugs with that number relate to anything i can find..........

This is how its written on the plug:

NGK PFR6B-11B

 

I can get NGK PFR6B-11C

 

Are these ok?

The supplier says he cant get 11b's, only 11c's, is there much difference between the two?

The 11c run colder for reduced risk of detonation. Smithy can supply the 11c ;) http://www.smithys-place.co.uk/engperf.php

That's cos your supplier ain't top dog like me fella :)

Difference is a slightly longer shroud in the 11b's which further helps fight against detonation, best pleace to get em is click the BIG square advertising box in my sig :dance:

cheers

Hi Paul,
