What spark plugs?

[OOO]

I don't know what to tell you,
It's been 20 years that I have my car and 20 years that the motorcraft spark plugs have denso in the box.
Another example I have Bendix TCAs from news and there is the Ford V85..... ref and the ball joint TRW like the original ones.

Do you have bendix part numbers for those tcas?

[ablc]

yes but nothing anywhere
841584b
14-tc-3378-x same TRW
Other side i haven't number but 14-TC-3377 are ok

i find these to 041635B and 041634B

AGPR12PP are Denso PK20PR
if i say no nonsense :
AGPR12PP8 are Denso PK20PR-P8 in Motorcraft box and it's for big turbo P8 it' distance between the spark plug electrodes so 0.8 mm
AGPR12PP11 are Denso PK20PR-P11 in Motorcraft box and it's for small turb P11 it' distance between the spark plug electrodes so 1.1 mm

I have a BT running circa 28psi boost, 500bhp and on wasted spark. Would any of the above be suitable? I have 071c's at the moment, but the car tends to miss on them from time to time.

wasted spark it's like small turbo ?
What gap on 071c ?
would you use only Ford motorcraft ?
testing the NGK BKR9EIX WITH 1 mm gap
Mine have 0.6 mm gap but no wasted spark.
But i have no experience with wasted spark.
If i understant small turbo have more gap because not same thing for igintion ........( wasted spark ?)

used to run 071C's on my stage 3 escort at about 360bhp ,this past year with less than 700miles had 3 sets of 71c's gapped at 0.6 from Matt lewis and nothing but misfires . had a set of Champion C59 's on shelf fitted them and its like a new car..been told to fit Denso as there better plug ?until I read above post

Thanks Mark. I've never used Denso before. Can you comment at all on the tip failures some folk have cited? Have you ever experienced this?

Not seen any problems with them and used for about 15years now.

I've bought Densos for mine now, they're in and the car started up fine on them.

[Cochyn]

Everything has potential to fail, you just hear about it more in high numbers of people who use the new fads around. So a lot of Mk1 Focus RS owners experienced denso failures because they all used them at one point. I swear by 071c plugs for the Cossie, despite having had a few misfires with some. But never had a tip fall off though.

Thanks Mark - that's good enough for me. What would you recommend they are gapped to?
