Hey does anyone know anything about these power making spark plugs jmm use????? wat brand and were u get em from??

They are Autolite - do a search at Fordforums and you should find the part number (sorry I can't recall what it is right now).

I had a set in the car - they ran fine - ie. at least as good as NGK etc. I currently don't have them in the car as one has a crooked centre electrode and I haven't got round to getting a replacement for it. I think it was running ok even with that electrode - I only took them out because number 3 plug was getting dirty - so I replaced the whole set withj NGK - but the problem turned out to be the plug lead (was also causing smokey exhaust in the morning).

JMM recommend and use those plugs because they reckon they get better figures on the dyno with them - ie. can run more advance.

They are autolite 985's. You can get them for $18 a set in Geelong.

is it just me or is that heaps cheap?

i just payed like 130 a set of plugs (not autolite) for mine, granted there is a couple extra..

Must be you as I only pay $16 for NGK.Most I ever paid was $30 at a Ford dealer.

well i payd bout 130 for mem for 8 x New NGK Iridium Platinum fitted.

thats cause you got iridiums....they ain't cheap. i think about $70ish for a 6 cyl

I run iridiums and never had trouble with them im thinking at the next dyno day throwing my car on and doing a few changes such as spark plugs and air setup to see different dyno results

with fords iridiums (used on the xr8's and xr6t's) you'll notice a diff on the dyno.. and most especially with lpg too ..

get them from ford direct and not thru repco/etc as they're more expensive.. cant remembre part number tho!
