BMS Mini Cooper S N18 JB+


  • £299.03
    exc. VAT £249.19

JB+ adds up to 20whp and 30wtq


Featuring quick plug and play installation the N18 JB+ adds up to 20whp and 30wtq to your N18 equipped MINI. Fuel economy is unchanged during normal driving and the tuning works in conjunction with the DME rather than against it ensuring optimal but more aggressive boost levels with air/fuel ratios and timing to match. Boost is increased 2-4psi on average depending on the climate and conditions. Unlike other N18 piggyback tuners this one actually works and completely transforms the driving experience. This is how the car should have come tuned from the factory. Literally installs and removes in less than 20 seconds.

CARB Approved Under Executive Order (EO) No. D-744 for all 2011-2015 MINI Cooper S and MINI John Cooper Works models equipped with a 1.6L N18 turbocharged engine.
