BFMK2 issue just started: Full boost loses power and sounds kind of like rev limit

[traffic]

Just about to get a set of coils. I assume the genuine Ford ones would be the best? But just looking at these genuine ones on ebay: http://www.ebay.com.au/itm/Genuine-Ford-BF-Falcon-Ignition-Coils-Set-Of-6-All-4-0L-Engines-XR6-XT-RTV-F6-/151949507235 and the listing says "NOT RECOMMENDED FOR MODIFIED TURBO'S RUNNING HIGHER THAN FACTORY BOOST" - is this true? Is there a different brand that are better? I'm running 14psi.

 

Cheers.

Totally wrong,

Just go to a local ford and get them there, they are $38 each or $230 for 6, then get new plugs from repco or supercheap and do both at the same time.

Sweet thanks for the reply. Replaced the plugs last weekend hoping that would do it, I'll go with the genuine Ford coils.

What plugs did you use?

I replaced them with the same ones that were in it. NGK Iridium Spark Plugs BKR6EIX-P.

Well done,

Did u check the gapping and gep to .7 or leave at .6? This could also cause a slight miss but highly doubtful when new.

That plug is gapped @ .8mm out of the box

[BAXRTUTE]

Ahhh I thought it was at .6 for some reason.

Should he not gap it to .7? Or not a big issue in your opinion luke?  

[Ralph Wiggum]

6 in the label is the heat range. Depends on boost level but .8 should be fine in this case.

I didn't check the plugs, just installed them as they are stock.
