They're similar to the 4C coil packs They have about 5000 miles on them. $150 + shipping.
Here's some info from an NGEN Customs & Performance post:
Upgrade your ignition system with a set of NGEN Performance Ignition Coils! These ignition coils are engineered to fuel the powerful combustion needed to maximize performance. These ignition coils will provide higher voltage and increased energy compared to the factory Beru coils. These ignition coils were designed/manufactured exclusively for NGEN Customs & Performance. These are a direct replacement and fit in the stock location, making changing these coils very easy. If you are running Euro+Drive (particularly Phase 2+) or an ECU Piggyback (Euro+Drive Lite,RRM Ultimate, EC Unichip, etc), you need the hottest and strongest spark possible to burn your fuel. With the increased voltage and energy output values, your cylinders will get the spark they need to maximize fuel burn. We have been running these coils on our Abarth for over 6 months. Since upgrading to these coils from the factory ones, we no longer experience any breakup/misfire over 5800+ RPM (like many experience when running a tune/piggyback with the factory coils). We have also had several Beta Testers run these ignition coils with identical results. Brisk Spark Plugs are highly recommended to run with these coils but not required.
