Fuel Injector Clinic Six Cylinder 2150cc SHORT Custom Injector Set - 38mm Height - 11mm Top O-Ring Diameter - 21mm Bottom O-Ring Diameter (2150-38-11-21-6)
The Fuel Injector Clinic 2150cc SHORT Custom Injector Set is engineered for extreme horsepower six-cylinder engine combinations that require exceptional fuel delivery in a compact injector package. Featuring a 38mm SHORT body, these injectors are an excellent solution for custom intake manifolds and applications with limited injector clearance. Despite their massive flow capacity, advanced injector technology delivers excellent low pulse width control, resulting in smoother idle quality and superior part-throttle drivability. Every custom injector set includes solder-in pigtails for custom installations.
Each injector is individually tested and dynamically flow matched using Fuel Injector Clinic's proprietary Data Match Technology to provide outstanding cylinder-to-cylinder consistency. Every injector is individually serial numbered and supplied with a comprehensive Data Match Sheet containing precise flow and latency values, making ECU calibration more accurate and repeatable. Every injector is flow tested at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees F and is backed by Fuel Injector Clinic's Lifetime Warranty against manufacturing defects.

Important Fuel Compatibility Information
CAUTION: The internal construction of this 2150cc injector contains a seal that has been found to swell when exposed to MTBE found in oxygenated race fuels such as VP Import and Q16. This swelling can significantly reduce injector flow, making these injectors unsuitable for use with MTBE oxygenated fuels.
When using alcohol-based fuels such as E85, Fuel Injector Clinic recommends following proper injector maintenance procedures. Extended storage while exposed to alcohol-based fuels may increase the potential for corrosion if recommended care guidelines are not followed.
Fitment

FAQs
What are the benefits of the SHORT 38mm injector body?
The compact 38mm design is ideal for applications with limited injector clearance while delivering the same 2150cc flow capacity, excellent idle quality, and precise fuel control.
Can these injectors be used with E85?
Yes. These injectors are compatible with E85 and other alcohol-based fuels, but Fuel Injector Clinic recommends following proper maintenance procedures if the vehicle will remain unused for extended periods.
Can I run VP Import or Q16 race fuel with these injectors?
No. Fuel Injector Clinic specifically recommends against using MTBE oxygenated fuels such as VP Import and Q16 because they can cause internal seal swelling and significantly reduce injector flow.
