Important Fuel Compatibility Information
Do NOT use these injectors with MTBE oxygenated race fuels such as Q16 or VP Import. Fuel Injector Clinic advises that the internal seal used in the 2150cc injector can swell when exposed to MTBE oxygenated fuels, significantly reducing injector flow. If operating on alcohol-based fuels such as E85, proper injector care during extended storage is recommended to help prevent corrosion.

FAQs
Can these injectors be used with Q16 or VP Import race fuel?
No. Fuel Injector Clinic specifically recommends against using the IS834-2150H with MTBE oxygenated fuels such as Q16 or VP Import because the internal injector seal can swell, resulting in reduced fuel flow.
Why are these large injectors still easy to tune?
Fuel Injector Clinic uses proprietary Data Match Technology to dynamically flow match each injector, greatly improving low pulse width control for smoother idle, better drivability, and more accurate ECU calibration despite the injector's massive flow capacity.
