Mini Gen 1 GTT Fuel Injectors.


SKU: N/A Category:


Using injectors too big can cause poor running problems at idle and light throttle. 440cc is the optimum size injector for any supercharged Cooper S and will achieve 260bhp running only 80% of its maximum output/duty cycle. Any ‘Injector size power output calculator’ website will confirm this to be correct.
We stock, 380cc, 440cc & 550cc. Our injectors have the correct OE electrical connectors, the correct physical size, correct spray pattern and correct electrical impedance. a remap is not normally necessary (the cars “smart” ECU learns as you drive)

Note: Please contact us for availability if you require 550cc injectors.(For turbo conversions 300 BHP and above)
Fits: Gen 1 Cooper S (also JCW / GP1)
