den1 Posted May 4, 2011 Share Posted May 4, 2011 The coil-packs on my Supra are 17 years old . I am considering replacing them... http://www.mkivsupra.net/vbb/showthread.php?210757-*NEW*-Super-Spark-Coil-Packs-for-1JZ-2JZ Does anybody think after 17 years of service these things must be nearing the end of their efficient operating life??

jevansio Posted May 4, 2011 Share Posted May 4, 2011 That's what I was thinking, if you're going for lots more power then sure, but if you're just wafting lazily round in an auto then save your money Link to comment Share on other sites More sharing options...
johnny g Posted May 4, 2011 Share Posted May 4, 2011 Hmm - always good to see different points of view Link to comment Share on other sites More sharing options...
Robzki Posted May 4, 2011 Share Posted May 4, 2011 Hmm - always good to see different points of view I'd change 1/2 of them and see if its any different, then you've only wasted half of your money, send me 50% of the saving on the rest and your in a 25% net profit. I'm good to you Link to comment Share on other sites More sharing options...
