Been tracing an intermitent problem where the engine drops a cylinder after fouling a spark plug . Think it might be bad coils so I rang the local Subaru stealership and was quoted $268 per coil . Ok time to get off the floor . Now I want to know if any one knows where I can get a set of after market coils that are at a more realistic price before I have to spend over $1000 dollars on a hunch.

Bosch has gone to China not long ago and they have differnet type of coils, you need either Bosch HEC-716 or Bosch BIC800 type of coil. Call Bursons/Repco and ask if they have one or not after market type. Its about roughly $60, there is another one you can get is Tridon TIC050, its about $45 something..

Picture of Tridon TIC050 below

They look nothing like the ones I have on my car . My car was Australian delivered so it has the ones that go straight on to the plug with no plug lead .

Only heard of after the fact, of one of these whole cars being sold for $2000, another one bent at $1500. Makes for a cheap car after you pay for the coils

Someone has said Bosch for these coil on plug twin cam EJ's. Consult Bosch online or local parts guys?

It is a common thing for people to go for a remotely mounted coil and then run leads instead of the coil on plug set up from the factory. The only reason it is done this way is price. About $250 all up for a set of 4 compared to over $1000.

Can someone that has done this conversion post some photos so I have some idea of where to mount the coils and anything else that could be a trap for young players . thanks heaps

Here it is

This is what AP was linking to....

I've done this myself but not quite like this guy did. I used the Bosche HEC716's. Yes you have to remote mount them with leads, quite short ones though.
I only installed mine a week or two ago and it's made a bloody great difference. The Bosche come with their own brackets and are such that an install to a Liberty requires no custom bracketing at all, they all bolt into existing bolts in the engine bay conviniently close to where they need to go. Very easy install, just need to solder 8 wires basically.

and I made a couple of ghetto brackets to mount them in pairs,thus:



then attached all the relevant cables/leads:



wanted to utilise the 'airspace' between the back of the lhs headlight and battery,(above the horns,) to mount one pair,so another ghetto bracket:



it's held in place by a bumper bar bolt and inner horn mounting bolt:



and with the pair of coils fastened to it:



and the coils on the drivers side are tucked in under the back of the headlight,(bit hard to photograph,sorry):

You can use the later model (two wire ones) with the single bolt just need to cut the brass insert for the bolt flush and use a longer bolt of the same size as original thread M6.
Cardiff Automotive sells these around $80 plus postage.

Another option is a set of LS1 coils the third wire is only for grounding.

And Another option would be using Hyuadai Excel coils. Did some research on these for a turbo v8 project
these are one of the most powerful oem style coils around.

Go to a mechanic with an coil tester get them check it out.

Also check the injector it may not be sealing of properly causing excessive fuel for that cylinder (swap coil to another location see if fault goes with it)

Make sure the gaps are right on the plugs as higher boost levels can have a negative effect on spark jumping capabilities.

Try closing the gap a little.

Also once the plugs foul they have tendency foul again (if they foul replace)
