Upgrade injector 4-hole kit of 2 BMW R850 R1100 NEW 13641341352

A modern 4-hole injector is generally an improvement over the original single-hole Bosch injectors fitted to the BMW R850 and R1100 because it atomizes the fuel much better. The main advantages are: Finer fuel atomization – Four smaller spray streams create much smaller fuel droplets, allowing the fuel to mix more evenly with the incoming air. Smoother idle – Better combustion at low engine speeds often results in a more stable idle. Improved throttle response – The engine reacts more quickly and smoothly when opening the throttle, especially from low RPM. Cleaner combustion – More complete burning of the fuel can reduce carbon deposits and exhaust emissions. Reduced surging – Many Oilhead owners report less of the characteristic light-throttle surging that early R850/R1100 models are known for. Potentially better fuel economy – If the injectors have the correct flow rate and the engine is in good tune, fuel consumption may improve slightly. Will it increase horsepower? Not significantly. On an otherwise stock R850/R1100, don’t expect more than 0–2 hp. The noticeable improvements are in: smoother running, better drivability, cleaner cold starts, and improved throttle response.
