FAQs
Do I need a pump upgrade or dual-fuelers with 300% over injectors?Yes. 300% nozzles can outflow the stock HPFP. A high-pressure pump upgrade and/or dual-fueler kit plus a quality lift pump are strongly recommended to maintain rail pressure.
Can these run on a stock turbo?Not recommended. Airflow will be a major limiting factor. Plan a larger single or compounds, proper intercooling, and engine hard-part support.
Are these brand-new or reman?Brand-new S&S Motorsport injectors built to S&S specifications and flow-matched as a set.
Is tuning required?Absolutely. Custom calibration is required to safely and effectively utilize 300% over injectors.
What about cores?S&S requires core returns; a surcharge applies if no core is returned. See product checkout details for current core handling.
