Cubes Posted November 12, 2006 Share Posted November 12, 2006 What sort of power/boost are you making on these after market coils? If its near stock or still stock turbo on measly 15psi boost then we can't tell if it will work once the combustion pressures are considerably higher. + the non-stock look. For $520 delivered splitfires are the way to go.

Cubes Posted November 12, 2006 Share Posted November 12, 2006 So you bought second hand leads and second hand coils. Second hand leads... Not exactly some thing you want to be doing if your running decent power and want to avoid a dodgy lead.

For $520 delivered splitfires are the way to go. where abouts can u get em for $520? Autobarn almost called the medics when they told me a new set of spitfires would cost over $1500 (cause i wasn't expecting more than $500~$600). i got the exact same problem as you guys. gotta get this fixed up soon Link to comment https://www.sau.com.au/forums/topic/140243-the-real-fix-for-dodgy-coils-misfire-at-high-rpm/page/3/#findComment-2666928 Share on other sites More sharing options...
Cubes Posted November 13, 2006 Share Posted November 13, 2006 $520. Buy from Nengun (~2-3week wait), Perfectrun (~7day wait). (Japan) You'd have to be silly to buy from auto barn and the likes. If you must buy a set in Aus grab a set from Slide. He sells them for $589 + postage.

Pulled my coils out and they look brand new but i still have a miss! your plugs look pretty shagged mate. close your gap to .8 and throw some new ones in.

cattivo_69 Posted March 1, 2007 Share Posted March 1, 2007 does the rubber boot connecting to spark plug just pull off? i had the missing problem 2 at 4500rpm and did the whole tape em up trick and u beauty, not a problem! in the last couple of weeks, since we have had this hot weather, one coil seems 2 be playing up when the car is at peak operating temp u will be driving, and all of a sudden it feels it drops a cylinder u put ur foot flat 2 the floor and it clears it self up, and then when at normal revs u can hear the miss again by looking at the coil there are a few hairline cracks but ive already taped them and still doin it when at normal operating temp?? any1 had this drama??

Cubes Posted March 1, 2007 Share Posted March 1, 2007 Tape didn't work for me. Grey Silicon worked. Your issue sounds strange. It wouldn't be a shagged ignitor? Check it plugged in well and there's no corrosion.
