Part number help

[Heff]

Hey guys, im struggling at the moment, been having some issues locating part numbers, 

basically, had some idle issues and general lack of power, 

removed and tested my coils, one is breaking down, and the other ones are looking like there gonna go soon aswell so im going to replace the lot, 

the problem - the part numbers on there are so old (guessing original) that most of the information is illegible or no longer visible, 

i phoned a main dealer (Woodford green) to help me find the parts, but they are unable to help as they cant search on imports on there system, 

its a ej255 engine, sg9 chassis preface any help would be helpful, or even a photo of the part number from another members coil 

FK0186 is what i suspect but am in no way certain 

thanks in advance

I assume you've got 4 individual coilpacks (one on top of each sparkplug) ?

I've only ever seen 2 types of individual coilpacks on imprezas ,92 to late 96 had two wires on the coilpack plug and later newage coilpacks with 3 wires on the coilpack plug . 

Most foresters have the same engine set up of a impreza of same year , can you post a pic of the coilpack on here .

As you'll probably find there's a impreza one the same and that would help widen the search
