COOPER S WITH PULLEY UPGRADE MULTI-GROUND:
Replacement performance spark plugs for the MINI Cooper S with the pulley upgrade, sold each. 'Cooler' temperature rating than stock. 14mm, 3/4" reach, 2 ground electrodes. Pre-gapped.

COOPER S WITH PULLEY UPGRADE - IRIDIUM:
We have selected the NGK Iridium IX Spark plug to run with MINI Cooper Ss equipped with the high performance supercharger pulley. This Iridium IX spark plug is rated a step 'cooler' than stock to reduce the likelihood of detonation, and features a .6mm iridium center electrode which offers superior ignitability without sacrificing durability. The tapered ground electrode of the spark plug increases flame kernel expansion, while the superior heat range design is ideally suited to the demands of high performance MINI Cooper S environments. Spark plugs come pre-gapped. 4 required per car.

• Fine Iridium tip ensures high durability
• Extremely durable under high heat
• “Trivalent Metal Plating” has superior anti-corrosion and anti-seizing properties
• Faster starts and quicker acceleration
• Better fuel economy and lower emissions
• Best platinum spark plug at an economical cost

COOPER & COOPER S - MULTI-GROUND PLATINUM:
A great replacement for the stock plugs in your MINI Cooper (non-S), or the equivalent to factory replacement for the Cooper S.

Multi-ground electrodes improve ignition capabilities and are less sensitive to increased voltage requirements due to gap growth. Designed to specific manufacturer ignition requirements in either supplementary gap, intermittent discharge, or semi-surface discharge, all for various firing tip self cleaning abilities. Platinum center electrode for extended life. Multi-ground plugs maintain all features of NGK's traditional plugs including corrugated ribs, pure alumina silicate ceramic insulator for greater strength and better heat transfer, copper core and triple interior seal. Pre-gapped to 0.032".

Some combustion chamber designs require that the spark plugs have the ground electrode placed to the side of the center electrode rather than below as on a traditional plug. This firing tip design tends to erode the tip of the ground electrode faster than a traditional plug, erosion at these points creates a larger gap between the center and ground electrodes causing plug misfire. Thus by having more ground electrodes you extend plug life. It is important to note that multi-ground does not mean multi-spark, there will still only be one spark at a time.

COOPER S JCW - MULTI-GROUND PLATINUM:
Same plug as above except with a slightly cooler temperature for the JCW Supercharger.

COOPER & COOPER S W/STOCK PULLEY - IRIDIUM:
A great upgrade / replacement for your stock MINI Cooper or Cooper S.

NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency. Pre-gapped to 0.032".

Advantages of Iridium spark plug types
Because of the properties of Iridium, the spark plugs centre electrode can be made with a much smaller diameter than with platinum types (0.6mm), Gold or gold palladium and copper/nickel types. This means that spark plugs potential difference is more concentrated and hence less 'spark jump' voltage is required - this can be as much as 5,000 volts less than with standard plug types. Ignition is improved and less strain is placed on the ignition system. Benefits of improved ignition/combustion include better fuel economy, increased power/acceleration and especially better throttle response.

Iridium: 8 times stronger than platinum, 6 times harder, and with a melting point 1200 degrees higher. New laser welding techniques make it possible to make a spark plug with an iridium electrode. The result is a plug that requires less voltage to spark, burns more of the fuel in the cylinder, and can spark at LEANER air/fuel mixtures, resulting in higher horsepower and better gas mileage. Although the plugs are expensive, you don't have to change them as often as garden variety spark plugs. The iridium electrode is extremely resistant to erosion, so it can last MUCH longer than a normal plug. (Longevity will vary by usage, fuel mixture, and other factors.)

PLATINUM'S USE IN SPARK PLUG CONSTRUCTION Nearly all spark plug manufacturers use platinum in one form or another on their long life or performance spark plugs. This is because of platinum’s high melting point, which makes it useful in two ways. On long life spark plugs a thin wafer of platinum is bonded at the firing point to the center electrode (and possibly ground electrode) solely so they don’t wear as fast as a traditional plug. On a fine wire performance plug, the very tip of the center electrode is made of platinum so that the fine wire tip will last longer. Do not be fooled, all platinum plugs are not created equal. Platinum is a very expensive precious metal, a $2 platinum spark plug will not have much platinum in it, and therefore will not last as long as a $12 platinum spark plug. Some platinum plugs have only the center electrode tipped with platinum, while others have both the center and ground electrodes platinum tipped.

Sold each. Order 4 per car.

Subject to manufacturers warranty.

IMPORTANT! - Use anti-sieze compound with proper torque (27 Nm or 20 ft-lb) when installing spark plugs. We recommend changing plugs on a 'cool/cold' engine.

Performance for Mini Cooper

MINI MANIA OFFERS A COMPLETE LINE OF PRODUCTS TO MEET YOUR PERFORMANCE GOALS

The process of finding the right starting point or next step in getting more performance for your MINI Cooper or Coooper 'S' can be confusing. To help narrow your search, begin by identifying your driving style and performance goals, then choose products which fit your needs.

For detailed, step-by-step instructions on modifying your MINI for optimal power and handling, you'll want a copy of MOTORING. In the mean time, here are some basic pointers on options that are appropriate for your driving level and interest.

 

MAKING THE MOST OF YOUR MINI
UPGRADING YOUR COOPER 'S'

The BMW MINI is a spectacular reincarnation of the classic Mini Cooper.The short wheel base, rigid chassis, light weight, combined with BMW engineering results in an exceptionally well handling car straight from the factory.

The stock design makes some compromises for the masses, being a delicate balance of performance, comfort and cost.But the stock MINI provides an excellent platform for the enthusiast where upgrades can transform the car to nothing short of phenomenal.

As with any internal combustion engine, horsepower and torque are increased by improving flow of air and fuel into and exhaust gasses out of the engine. Reducing rotational mass of engine and drive train components improves ‘responsiveness’ for better throttle response and all around drivability. Each upgrade provides an incremental increase in performance, but a ‘systemic’ approach offers the highest gains.

For the 1.6 liter supercharged engine in the MINI, the typical and proven sequence for upgrades are listed below. You can install each piece individually, or install one of Mini Mania’s Stage kits for the best performance at the best price.

  STEP 1: Cold Air Intake - The Mini Mania Cold Air intake improves flow by greatly increasing the airbox and filter size while maintaining air intake from outside the engine compartment. The airbox uses polished stainless steel for its exceptional heat shielding qualities. For detailed information, see Item NME2030.

  STEP 2: Cat Back Exhaust - Mini Mania offers three different stainless steel low restriction cat back exhaust systems with mild, medium, and aggressive exhaust tones. All three systems offer greatly reduced back pressure while maintaining gas velocity for optimum performance. Items  NME1020, and NME1021.

 

STEP 3: Supercharger Pulley Upgrade - Mini Mania uses a 15% reduction pulley that maximizes the supercharger speeds without exceeding specifications. Reducing the pulley diameter increases the supercharger revolutions at a given engine speed, resulting in a higher boost pressure and delivering more horsepower at that engine speed.This Pulley upgrade essentially moves the horsepower and torque curve lower in the RPM range.Part number NME5011.

 

  STEP 4: ECU Remap - The Electronic Control Unit (ECU) manages all aspects of engine operation including air/fuel mixture, throttle ositioning and ignition timing, just to name a few.We offer the UnichipShark Injector, and Evotech ECU upgrades which remap the software for optimal performance.

  STEP 5: Throttle Body Upgrade - The throttle body upgrade has a greater inlet diameter allowing more air to flow into the engine. The ECU recognizes the increased airflow and adds more fuel, resulting in more power. Part number NME6050.

  STEP 6: Performance Camshaft - The camshaft controls how much air and fuel enter and exit the combustion chambers. By increasing lift and duration, more air and fuel enters the chamber for a more powerful combustion. The Schrick Performance Camshaft optimizes lift and duration along with other parameters for greater performance using stock valves and springs. Part number NME6041.

  STEP 7: Exhaust Header - For off road use only. The exhaust manifold takes the spent exhaust gasses from the engine through a catalytic converter and into the exhaust system.The Mini Mania stainless steel exhaust header increases flow over the stock design.Using a hi-flow catalytic converter with the necessary flex joint, this header increases horsepower and throttle response. Part number NME1004.

  STEP 8: NGK Performance Plugs - The spark plugs ignite the air/fuel mixture once it enters the combustion chamber. A supercharged engine produces more heat due to the increased density of the air/fuel mixture.These ‘colder’ spark plugs reduces the combustion temperatures, thereby generating less heat. Part number NME3011.

  STEP 9: High-Flow Cylinder Head - The cylinder head serves to move the air/flow mixture into the combustion chamber and exhaust gasses out of the engine.Although the factory head works well, the flow can be increased through porting and polishing which increases the openings into and out of the engine, smooths the walls of the channels for less turbulence, and reshapes the channels for optimum flow. Better flow equals more power. Part number NME6001.
