Recommended for all MINIs running any MANIC TUNE or aftermarket power adders!

All modified Gen 2 turbo engines that are putting out anything above factory rated power suffer from a very marginal and weak ignition system.  The coils will not support any increase in power and the factory spark plugs are cheap throw aways.  After many years working on and modifying Gen 2 Turbo MINIs we have a cost effective solution. Install a set of NGK Iridium spark plugs and a set of Bosch High Performance pencil coils and the problemsome high speed-high load misfire is eliminated. You will be surprised on how much better and smoother your MINI runs.

Why MINI coils fail.

The design of the ignition coil on the gen 2 MINI is not ideal.  All the control electronics and amplifier windings of the coils are housed within a sealed tube deep inside the engine surrounded by 250 degree F oil and zero cooling air. The coils never get a chance to cool-off. After you shut your car off the coils contine to bake until the entire engine cools down.  Heat destroys anything electric.

A fresh set of Bosch Ignition coils will immediately fix the high speed or high load misfire you are experiencing. High-performance ignition coils from Bosch ensure a reliable voltage from the start, and more ignition energy so your engine starts and runs smoothly. Long recognized as world leader in automotive electronics, ignition and fuel systems, Bosch's quality, innovation, and experience are the foundation of the entire line of engine management components. This does not fix the design flaw of the Gen 2 ignition system but it is a very cost effective repair and should last 30,000-50,000 miles before replacemnt is needed again.

High-Voltage Ignition Components

High-voltage ignition components designed for a normal charged or low-pressure boosted engine will sooner or later prove inadequate to spark properly through the denser charge mixtures encountered as boost increases significantly. Stock-heat-range spark plugs can contribute to knock or pre-ignition, and should be replaced with plugs at least 1-2 ranges colder for street turbo engine.

If the ignition is too weak to fire reliably through the super-dense charge mixtures of high compression as a result of high-boost supercharging or turbocharging, the engine will begin to misfire under heavy load. Common first aid when the high-side ignition voltage becomes problematic is to decrease the spark plug gap down to 0.020 or even less. A better solution is to replace and upgrade the ignition coils with fresh OEM type of high voltage versions if available..

NGK Iridium Spark Plugs

Designed specifically for the performance enthusiast. Iridium IX S spark plugs offer extreme ignitability, improved throttle response and superior anti-fouling. The most recommended and best performing spark plug for stock and modified MINI Coopers with N14B & N18B turbocharged engines.

  • Sold in a set of 4
  • Fine Iridium tip ensures high durability and a consistently stable spark
  • Iridium alloy has extremely high melting point, perfect for today's high-tech, high-performance engines
  • Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties
  • Outstanding acceleration, high fuel efficiency and durability
  • Ultimate design, technology and performance.
  • 0.6mm laser welded iridium tip
  • Iridium alloy is extremely durable against heat, corrosion, and electrical wear
  • Tapered ground electrode to minimize "quenching effect"

Select desired heat range when ordering.

  • Standard Heat Range: Best choice for daily driver with minor engine modifications and a Stage 1 or Stage 2 Manic Tune.  We do not recommend +1 colder spark plugs for street driven daily drivers.
  • +1 Colder Heat Range: Recommended for cars with performance engine mods, Stage 2 and above Manic Tunes and are used in sustained high RPM track event driving running 100+ octane race fuel.
