Hi I go on tour in europe every year and last year was the first with my supercharger, towards the end of the tour one of my coils (passenger side) started misfiring but once everything had cooled down it was fine and I reset the error code etc, this was the last day in the heat and it was very hot. It's been fine since I've been back home. I assumed this was down to the engine bay temperature rising, I've seen a few posts on coils failing due to this. https://www.pointmeby.com/2017/09/10/86-brz-frs-p0351-cel-p0353-coil-pack-how-fix/ I was thinking of upgrading the coils which is around £800 but a friend also suggested a vented bonnet https://www.demon-tweeks.com/seibon-carbon-fibre-bonnet-ts-style-seihd1213scnfrs-ts/?istCompanyId=a2904180-3a7d-4e56-b876-cf81c9512180&istItemId=-xpitqlxmxw&istBid=t&gclid=Cj0KCQiAj4biBRC-ARIsAA4WaFgI1WlBEaP-7yoNrvIcfRf0u9eFNuUjKn2CLFhMGoO277owtNzCGtoaAqgKEALw_wcB&gclsrc=aw.ds Not only could this solve the problem but it would also look nice. Does anyone have any experience on coils or if the bonnet vents are effective at lowering temperatures enough to stop this happening again? Thanks Andy

I had torque running with an odb2 reader but I can't remember the exact code but I remember it pointing at the coil or spark plug for the fault, I'm glad it wasn't as I didn't relish the thought of removing either in that heat! That probably explains the lack of info on the web then if it's not a real issue. It's a Harrop Supercharger. It's never happened before and not since so I suppose it could have just been dirt in the fuel maybe. Thanks for the reply.

I went away for a 10 day tour to Italy recently as I do every year in my car, this is the second in the GT86 and with my SC fitted, it did take a lot of abuse but one very hot day I had a report of a miss-fire on cylinder #2, it seemed to cure itself after about 10-15 minutes after turning the engine off but my friends suggested a fuel cooler which makes sense if fuel overheating was the problem which sounds likely? Has anyone fitted a fuel cooler? If so do you have any recommendations on which size, make to use and where best to fit, I'm assuming cooling the fuel on the return is best? Thanks
