Bosch f5dp0r still failing?

[s2dk]

Hello
Do they still fail?
What about useing ngk pfr7b or 8
Any other great plug to use on a 450 hp s2 aby?
Around 1.8 2.0 bar boost? 99 vpower fuel

NGK BKR7EIX is the plug to use. 20 valves seem to be very happy with those.

I used NGK BKR7EIX before, good plugs gapped to .6mm. However now I am using Denso IK22, I feel they are much better than the NGK. For your power level however maybe the NGK will not be strong enough.

Im aming for 500 in the end though
What about going 8eix?

[rynaqui]

For 500 8EiX will be better than the 7EiX.

I'm a fan of Denso PK22 PR8's, they perform very well, their quite expensive for a copper cored plug but seem more reliable than any other plug I've tried over the past couple of years in my RS2+ spec S2.

I have never heard of these plugs before, maybe it is something I will try the next time I require a plug change

[s2dk]

The denso one or ?

NGK BKR7EIX is working well for me with just over 400 horsies. Can't define if there's any actual performance improvement, but certainly detriment to it either. Can sleep easy at night as well

NGK for the win. BKR8EIX in mine, and not a single hiccup.

What hp power lvl do u run on ur 8's

[s2dk]

What hp lvl do you run on 8eix?

[hunker7]

Mine is mere 260, but had issues with Bosch and LPG setup, was misfiring at higher revs, used NGK and problems solved.

EDIT: These were recommended by someone who's car is running 450HP I think.
