Norcal Dynamics B46 B48 B58 S58 High Output ignition Coil Packs

Set of 6 Norcal Dynamics is pleased to announce the availability of our most recent product, "ND - High Output Ignition Coils (HOIC)," after months of trial and error and testing we have finalized our coils even running it on our customers builds and our shop build making over 550+ whp without any issues. These loops are an extraordinary redesign for the people who value the general driving experience of their vehicle as a regular vehicle and incredible for the individuals who will stretch the boundaries of their motor. As the OE B58 style coil packs are an incredible and well performing start loop from industrial facility we actually figured out how to arrive at the constraint of them through straightforward tuning. The original coils cannot maintain charge for an extended period of time before releasing energy. We took advantage of this limitation to enhance the upgraded coil. Stay can be held for a more drawn out timeframe (kept in Ms). The more energy it stores/charge during the abide period the more energy/charge it discharges when it comes time to fire. The OE weren't capable of holding such charge, they would prematurely release the energy pre-igniting the coil pack and firing again when commanded resulting in a double fire which causes ignition break-up/misfires.   No changes are required to run the ND Upgraded coils on any of the cars listed below. These are the BEST absolute coil upgrade for B48 B58 S58. For the best results we do NOT recommend gapping spark plugs when using these coils, gapping plugs only deteriorates the burn efficiency of the ignition setup. The larger the gap the more efficient burn you will get. ("0.030-0.031") Highly recommend OEM champion spark plugs straight from BMW dealership. When it comes to custom tuning and adjustments we have seen the best results when raising the dwell time to 3.7Ms. Please consult your tuner if you want your dwell time optimized. Otherwise these are plug n play and will perform better right off the bat!
