These will work great for E85 builds where huge fuel systems are required.

These are high impedance injectors so they are plug and play.

Slim design saves 276 grams total over 42# Lucas injectors.

Injectors of this size require PCM programming on all applications. L67 cars will chose EV1 connectors, and L32 cars will chose the EV6 connectors. 2001+ NA cars require injector connectors or adapters.

All ZZP purchased injectors come with dielectric grease and are packaged in a reusable plastic case to store your factory injectors safely.


Coil Resistance: 14 Ohms / High Impedance / High-Z (No ECM driver modifications required).
Static Flow Rate @ 43.5PSI ( 300kPa ) w/Gas: 80 lb/hr = 630 cc/min = 850 cc/min.
Dynamic Flow Rate: 18.6 mg/pulse 2.5ms PW, 20 ms Period.
Series: DEKA 4 ( DEKA IV ).
Orifice Type: Multi-orifice.
Spray Pattern: 30 Degree Spray Cone.

Good Injectors, Authentic Siemens And Great Service. I Had These Injectors For 3 Years And Had 1 Injector Fail. It Would Get Stuck Open. This Was About 35000 Miles And Way More Engine Hours Than You Typical Daily Driver. Also Injectors Are Too Large For Pump Gas And Will Cause Misfire At Idle. Great Injectors For High Fuel Demands.

Deka 80# injectors

I received them fast. I have not installed them yet but I expect that they will work perfectly. I purchased Deka 60lb injectors from zzp and they worked great.

Too Large For Elevation.

Got These Injectors For A Turbo Set Up On E85. Holding Off On E85 And Got The Injectors Tuned For 91 Pump Gas. I'm At 5,000-7000 Feet Elevation And These Injectors Are Too Large If Running These On Pump Gas For The 3800. The Injectors "Bottom" Or Lowest Amount They Can spray Is Not Low Enough To Maintain 14.7 At idle With No Load. 3800s Will Misfire And Set Multiple Cylinder Misfire Code If Let Idling Long Enough. (misfires stop when vehicle is stopped and in gear. Misfires also stop in Park Idling with A/C On) These Injectors May Not Cause This Condition On Pump Gas At Sea Level And Will Most Likely Not Occur At All With E85. They Work Fine And Haven't Had Issues Otherwise. If Your Like Me And Get These And Misfires Occur At Idle In Open-Loop Operation...And Absolutely Every Other Possible Cause For A Misfire Is Ruled Out... The Above Is Why And This Is Unavoidable Unless You Set Your Idle Target AFR To 12.0 XP
