Bavauto High Performance Ignition Coils

Since I don't know the maintenance history of my car before it came into my hands, I am replacing a lot of stuff as funds come in so that I can be certain about when stuff got done, etc.

What do you know about Bavarian Autosport's "High Performace" ignition coils? They cost $400 for a set, which is 66% more than OEM coils would cost at $60 each. Are they worth the extra dough? Bavauto claims better fuel economy, increased hp and lb-ft, but present no figures

Thoughts/comments/testimonials welcome.

- Daniel

my thoughts are that they really arent too benificial to a near stock car. i cant really seeing you needing that extra bit, i consider a mod like this to be for someone who has pretty much done everything else to the car, or has maybe gone FI. really your not gonna see any substancial gains from them, to be honest just stick to the OE ones they are very good anyways.

Thank you for the prompt reply. That all makes plenty of sense to me. I'll stick to OE.

Well, quite frankly, the stock ones already give you a spark so hot that you can't use high performance plugs or they'll fry them. I'd say that's pretty fucking good.

Edit: Just to inject some science into this, essentially what happens is that because the platinum plugs have a lower resistance, they transfer more of the energy from the coil to the spark itself, and it becomes so hot that it can actually damage the plug itself, and it makes the combustion chamber temperature go too high as well and you can suffer from predetonation, especially with more aggressively timed aftermarket chips installed.

No, don't worry. It's cool. I'm taking it back for us.
