A bigger injector isn't always a better injector! It can flow a large volume of fuel at WOT, but if the spray pattern is poor, you can expect poor idle quality, poor drivability, increased knock propensity, soot, NVH (noise vibration harshness,) and tuning difficulty. Additionally, the wrong spray pattern can result in liquid fuel impinging in the cylinder walls, causing oil dilution, which increases mechanical wear to internal engine components.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003ePrecision Raceworks is committed to providing only quality products, and has developed partnerships to deliver an OEM level of quality on our injectors. \u003c\/span\u003e\u003c\/p\u003e        \u003cp\u003e \u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e \u003cb\u003e \u003cstrong\u003eStage 1\u003c\/strong\u003e\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003e \u003cstrong\u003eWHP Potential - Gasoline: \u003c\/strong\u003e 780 WHP*\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eWHP Potential - E85: \u003c\/strong\u003e 630 WHP*\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eTune Required: \u003c\/strong\u003e YES\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eFlow Rate:  \u003c\/strong\u003e14.1 g\/s at 100 bar\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eFlow Rate over stock: \u003c\/strong\u003e 35%\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eMax Operating Pressure:  \u003c\/strong\u003e220 bar \/ 22 MPa \/ 3200 psi\u003c\/li\u003e\n\u003c\/ul\u003e \u003cb\u003e \u003cstrong\u003eStage 2\u003c\/strong\u003e\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003e \u003cstrong\u003eWHP Potential - Gasoline: \u003c\/strong\u003e 880 WHP*\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eWHP Potential - E85: \u003c\/strong\u003e 700 WHP*\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eTune Required: \u003c\/strong\u003e YES\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eFlow Rate:  \u003c\/strong\u003e17.3 g\/s at 100 bar\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eFlow Rate over stock: \u003c\/strong\u003e 66%\u003c\/li\u003e\n\u003cli\u003e \u003cstrong\u003eMax Operating Pressure:  \u003c\/strong\u003e220 bar \/ 22 MPa \/ 3200 psi\u003c\/li\u003e\n\u003c\/ul\u003e        \u003cp\u003e \u003c\/p\u003e        \u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBmw 340i 2016 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw 340i Xdrive 2016 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw 440i 2017 to 2020\u003c\/li\u003e\n\u003cli\u003eBmw 440i Xdrive 2017 to 2020\u003c\/li\u003e\n\u003cli\u003eBmw 540i 2017 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw 540i Xdrive 2017 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw 640i Xdrive 2018 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw 740i 2016 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw 740i Xdrive 2016 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw M240i 2017 to 2021\u003c\/li\u003e\n\u003cli\u003eBmw M240i Xdrive 2017 to 2021\u003c\/li\u003e\n\u003cli\u003eBmw X3 M40i Xdrive 2018 to 2019\u003c\/li\u003e\n\u003cli\u003eBmw X4 M40i Xdrive 2018 to 2019\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFeel free to contact us at info@mlperformance.co.uk should you wish to double check!\u003c\/p\u003e        \u003cp\u003e \u003c\/p\u003e        \u003ch4\u003eCompatibility Check\u003c\/h4\u003e\u003cp\u003eTo ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch.
