These MSD Ford Blaster Coil-on-Plug ignition coil packs feature a patented winding design and direct bolt-in replacement. The improved spark energy and voltage of the coil packs, combined with their reliability, have made them a favorite of performance enthusiasts. They are designed as direct bolt-in replacement coils for many SOHC Ford V8 modular engines. The housing and installation are the same as the factory coils, but that is where the similarity ends. Inside the MSD coil packs, engineers used better quality materials to assemble the primary and secondary windings. The MSD Ford Blaster Coil-on-Plug ignition coil packs take the spark energy right out of the coil and put it across the plug gap to improve the combustion and output of the engine.

Davis Unified Ignition SOS ignition coil packs feature advanced technology to pack more electrifying voltage into them for pure ignition performance. The SOS (Sultans of Spark) ignition coils are designed with increased windings to boost spark output up to 40,000 V! That is a 60 percent increase in spark energy over the 25,000 V produced by the stock ignition coils. The higher voltage, along with an increased spark duration, allows spark plug gaps to be opened up. The larger gap exposes a hotter spark in the combustion chamber for an increased burn of the fuel mixture, resulting in more horsepower and better fuel economy. Davis Unified Ignition SOS ignition coil packs also provide quicker starting, smoother idle, and excellent throttle response. They are direct replacements for the factory coil packs and do not require any special modifications for installation.

Holley EFI Smart Coils are a bolt-in ignition upgrade for your Gen III HEMI or Coyote engine. Here's the difference over a stock coil: they produce more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. The Smart Coils are available individually and in sets of 8. * For Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 and Coil Extension Harnesses 558-326 for a plug-and-play solution. Features: * Direct bolt-on to factory valve covers * Same wiring pinout as other IGN-1A coils for easy plug-in upgrades (Will not work with factory wiring) * More spark energy than any other smart coil on the market for maximum fuel burn during combustion sequence * Low current draw means less demand on the electrical and charging system * Built-in ignitor for compatibility with Holley EFI and many other aftermarket ECUs * Maximum operating voltage of 18 V—for compatibility with both 12 V and 16 V electrical systems found in many performance/race applications

The basic requirements for a properly running engine are fuel, air, compression, and spark. A weak spark from your ignition system can result in misfiring under high-load driving, and spark blow-out under high boost, which is bad for performance. Mishimoto ignition coils are high-quality replacements that can bring your vehicle up to Stage 0 before moving on to horsepower adding modifications. They are designed and tested to meet or exceed OEM performance standards and are available as a single coil or in sets. Once installed with a set of new spark plugs, you can expect a refreshed ignition system with improved engine startup, a smoother idle, and restored performance. The primary frame of Mishimoto coils is constructed from extremely robust phenolic resin, ensuring optimal longevity in high-temperature environments, while a precision lower rubber boot provides a barrier against moisture entry into the plug well, eliminating chances for spark plug contamination. Each coil is pre-lubricated with dielectric grease to prevent corrosion and ensure an optimal connection between the spark plug and coil. Swap out your worn or defective factory coils with Mishimoto's ignition coils, and as with all their products, the coils include their signature Mishimoto Lifetime Warranty. Choose the ones designed for your vehicle in the quantity needed.
