bskey Posted August 3, 2007 Share Posted August 3, 2007 but you have 4 coil pacs instead of 1, so it can be more expensive. life in spin cycle..... Link to comment Share on other sites More sharing options...
mwiener2 Posted August 3, 2007 Author Share Posted August 3, 2007 or less expensive. I only have to replace one small one instead of a larger 4 in 1 or 2 in 1 My Mods List (Updated 8/22/17) 2005 Outback FMT Running on Electrons Link to comment Share on other sites More sharing options...
StupidDent Posted August 4, 2007 Share Posted August 4, 2007 or less expensive. I only have to replace one small one instead of a larger 4 in 1 or 2 in 1 +1! How much is 1 coil for legacy? it's about $200 for my 00RS for the 4 in 1 coil pack. one of the reason why I haven't try to replace it. I know injector could be the one causing my misfire. However, cylinder 4 is also the most difficult one to remove. Link to comment Share on other sites More sharing options...
mwiener2 Posted August 4, 2007 Author Share Posted August 4, 2007 I havn't looked into it yet, but a quick check nline shows 2 parts. One is $130, the other is $75. I don't know which is right. I have to call the parts department. edit: Just called dealership. They want $99.98 + tax and they don't have it in stock. He said there is only one in the country and it's not in Colorado. Part number is 22433AA540 edit again: Subaruparts.com has it for $76 but not in stock My Mods List (Updated 8/22/17) 2005 Outback FMT Running on Electrons Link to comment Share on other sites More sharing options...
StupidDent Posted August 6, 2007 Share Posted August 6, 2007 wow... i guess it's cheaper in terms of 1 time purchase. but pretty expensive in terms of coil for coil... then again, these kind of thing shouldn't break too often... should only happen to high mileage cars.

laramieskibum Posted May 9, 2010 Share Posted May 9, 2010 120k on my obxt and 3 of the coil packs look exactly like the OP's pic. Anyone bother to replace them or is it superfical? Less iron = different magnetic field, but there is still a lot of iron there.....see op's pic. Link to comment Share on other sites More sharing options...
TRS Posted May 12, 2010 Share Posted May 12, 2010 Bad coil... http://i23.photobucket.com/albums/b380/TRS60586/Misc%20Legacy/2010-05-04002-1.jpg Spark was escaping the coil (black burn marks) and traveling along the outside of the boot (white burn marks) before jumping to the engine block.

1SIKLGT Posted December 16, 2015 Share Posted December 16, 2015 Is there a way to repair the magnets?? Link to comment Share on other sites More sharing options...
762x39 Posted December 18, 2015 Share Posted December 18, 2015 It doesn't look nice... but that rusted stuff isn't the coils... it is just the iron core which functions as the electromagnet. The coils are still in tact..... That Is not the Iron core. Its called a core because its in the middle. The core could be made of any number of things including air (which would be no core, just a coil) but only the manufacturer could tell you unless you disassembled it. Different cores produce different electrical characteristics. The coil is just that, a coil. Its a coil or spiral-if you will- wrapped around the core (if it has one). It takes in the incoming voltage and steps it up to a higher voltage which is then transferred to the spark plug. The quantity of step up voltage is dependent on how many turns the coil is made of and what material the core is made of (if any). The above mentioned coil construction is completely sealed. If it wasn't sealed, it would suffer a severe loss in Voltage, be vulnerable to catastrophic short circuit hazards (i.e weather, water) and the car owner would also be exposed to hazardous high voltage conditions. That ugly rusted thing is the Heat Sink wrapped around the outside of the sealed unit. The Heat Sink is designed to wick heat away from the induction process. Excessive heat creates very high resistance in an electrical circuit which in turn will degrade the electrical components until they fail. The rust causes the Heat sink to no longer wick heat away from the coil. Electromagnetism is just a byproduct of the induction process which in this scenario is not wanted or needed. Any time Current is passed through a conductor a magnetic field is created. This is how electrical induction (i.e coil packs) works. Link to comment Share on other sites More sharing options...
762x39 Posted December 18, 2015 Share Posted December 18, 2015 Is there a way to repair the magnets?? There is no magnet included in the construction of a coil pack. Please see my previous post. Link to comment Share on other sites More sharing options...
1SIKLGT Posted December 18, 2015 Share Posted December 18, 2015 The heat sinks...are they repairable?? Link to comment Share on other sites More sharing options...
762x39 Posted December 18, 2015 Share Posted December 18, 2015 Since they are rusted, no, they would have to be replaced. I don't think there is anyone out there that makes replacements. Unfortunately, these coil packs were not designed with rebuild options in mind. If the sinks were designed with a less corrosive material, I'm sure they would last for many more miles. The less corrosive metals cost more which would drive up the cost of the coil packs which are all ready hanging around $100 buck a pop. Only in a perfect world could we have it all!

1SIKLGT Posted December 19, 2015 Share Posted December 19, 2015 Yeah that makes sense. I got one at O'Reilly but now the car seems to miss fire when I get into target boost. Cheap quality maybe?? Or maybe just the cold weather?? Link to comment Share on other sites More sharing options...
762x39 Posted December 19, 2015 Share Posted December 19, 2015 Yes, I'm sure the weather has the most impact on them. I bet the southern and west coast guys don't have coil packs that look like that. Don't forget all of the salt they lay down during the cold months. SALT SUCKS! It could be cheap quality. I ordered a coil pack from Rock Auto once and it was DOA. It was worse than the one I was replacing. Link to comment Share on other sites More sharing options...
mwiener2 Posted December 20, 2015 Author Share Posted December 20, 2015 Only use Subaru OEM coil packs My Mods List (Updated 8/22/17) 2005 Outback FMT Running on Electrons Link to comment Share on other sites More sharing options...
DonnyJagaru Posted December 22, 2015 Share Posted December 22, 2015 In days of yore they used to encapsulate laminations on ignition coils and transformers so they would rust. I'm guessing they don't do this anymore for cost-saving reasons. Link to comment Share on other sites More sharing options...
