Coil Packs for I6

BIGJB · 30-07-2008, 08:36 PM

Ok guys the handling and braking side of the vehicle is sorted.
The next mods are to help the performance side of things.
I am thinking that at 175klms the coil pack has prob seen its day.
In saying that what brand and even better what part number as well?
She has a I6 VCT in her.

I had to replace my coil pack not long ago, just a standard jobbie sent over from carbitz, but it cost me $120 (trade price) so id expect that the bigger name brands would be around the $150 mark (again trade price). while your at it, go for ICE pro series leads and NGK plugs (ZGR6B11). when you change the pack, there are 3 7mm bolts holding it down, one has an earth wire underneath the pack. dont forget to undo the plug before you undo the bolts. can be easier to remove the pack from under the car. but i found it ok to do just removing the airbox/snorkle and ducting so i could access it all from above. can be difficult at times, but doable.

As far as I know nobody makes an aftermarket version of these like what MSD do for V8 ones, youre best of just getting a new genuine one.

BIGJB · 31-07-2008, 08:34 AM

Now that I didn't want to here. Grrr....
Will have to do some research on that one. Motocraft parts are usually not the best.

you can get aftermarket mustang v6 ones from the states. explorer v6 ones are also the same, they have the same plug as an au1, the only thing you have to do is change a couple of the leads around because the firing order is set up slightly differently

Chamelion · 31-07-2008, 09:58 AM

I bought an aftermarket one from Supercheap auto for $106 incl freight (had to be ordered in, took two days). Works a treat.

Just an update for ya guys.
I have searched high and low but to no avail.
There is nothing out there in the way of an after
market performance coil pack for an I6.
So I guess the crappy genuine one it is in this case.
Thanks anyways guys.

Sorry John, I'll be buggered if I can find that picture of the three x 2 post MSD coild on here....

WoodysXR6 · 14-08-2008, 04:09 PM

I got a new bosch coil pack that looked the same as the one that come out my dads 1 Ute, For $76.00 at trade through global auto spares if that helps.

NC1183 · 14-08-2008, 04:15 PM

I got a genuine one from Ford yesterday and replaced it yesterday as well, like au2sw says, just remove the whole air intake system( everything before the throttle body) and do it from above. Definatly improved my car it now idles, and revs cleaner and smoother and changing the coil pack also fixed the annoying problem of my tacho jumping as it got reved past 2000rpm

BIGJB · 14-08-2008, 04:27 PM

No prob Daniel. I'll just get a genuine from Ford.
Thank god for trade prices hey.

What you mean fitting it guys..... I have yardies and a workshop for a reason. lol

Man u did it the hard way, Im a big guy and managed to get my arm in their lol.
At 1st i was like not gonna happen then kept at it and in the end found it quiet easy.

Did think twice at doing it that way though.

V8falcons · 14-08-2008, 05:49 PM

I bought a genuine ford AU2 (delfi?? brand on ebay for $95) after the gooses at repco supplied me with a series 1 item as they assured me they were all the same,he didnt like it when I told him ,I told you so!!!!!!!!! and reluctantly & rudely refunded $120 large, wont be using repco to buy any thing again ,my daughters has a better idea of parts than these jokers!

What you mean the hard way, i left the intake manifold on and put my arm/hand between it and the block, nice and hot too, or under the throttle body, plus its only 5 little bolts and three screws

Not necessarily Repco's fault, they use catalogues provided by the aftermarket parts suppliers they buy from. There are 2 manufacturers who do coolant temp sensors for I6's, whose catalogues both show the AU item is the same as the E-series, nothing could be further from the truth.

If you expect a salesman to personally have an encyclopaedic knowledge of every part fitted to every car sold, you'll find yourself dealing with Rain Man...

Even if they do I would imagine the firing order would be incorrect.

WoodysXR6 · 14-08-2008, 07:55 PM

you'd have to trial and error it ive heard it aswell it was a good mod.

Thats not hard to fix. Just change what plug the lead goes to.
I think the problem would be in the feed back circuit to the computer and what voltage/current it sends back. There was someone a while back who started to play with explorer coils.

Cheers

AU coil packs have 4 wires. 1 supplies power to charge all 3 coils. The other 3 wires trigger the coils - 1 wire per coil. So there is no "feedback circuit" from the coilpack to the PCM.

bodes-sh · 15-08-2008, 08:36 PM

yeah, i was going to play around with explorer coils, still have the stuff here, just haven't had the chance yet...i will see if i get time on the weekend to have a look at it...

BIGJB · 15-08-2008, 08:42 PM

Thanks for the different opinions guys. I am really keen to
work this one out by next weekend. That and new injectors
I can than get it on the dyno. Have set myself a goal of
havin it all done by end of the month if I can.
So all advice will be taken on board.
Cheers John

**Peuty** · 15-08-2008, 09:26 PM

Maybe the Explorer route might be worth having a look at?

b2tf · 15-08-2008, 10:00 PM

Wouldnt the firing order be controlled by the ECU? Worse comes to worse you can use an ignition controller like the DIS4 system and set it up that way, MSDs put out higher voltage than what the standard ford coils do too.

sly · 15-08-2008, 10:33 PM

The coil firing order is controlled by the ECU, it's just a matter of correct pairing of leads to get the right cylinder firing order in a wasted-spark system like this.

BTW bodes-sh, I've forgotten, was the Explorer coilpack like the EF/AU1 unit or the AU2/3 one?

StealthAu · 15-08-2008, 10:37 PM

I want to get hold of 3 of these

I'm sure it wouldn't be too hard to set up.

There's more to it than it looks. A sparky explained to me that the Ford coilpack is "smart" and doesn't need separate igniters. The GM coil however is "dumb" and needs igniters to fire it. I dunno what these are but I'm sure someone will be able to advise how to go about it & what you need.

ef/au1, but i really don't see any reason that anyone wanting to do this to a 2/3 couldn't get a plug (either from ford or a wreckers) to suit a 1 coil pack and just rewire it...

i will try and get hold of the set of leads this weekend and give it a go
