The explanation of low impedance injectors sure explains why the Japanese were using so many low impedance injectors even back in the 80's

[@kelvinleong915]

So sir u recomemede low impedance for evo3

[@nicefknmodel2201]

I needed this. Thanks for the explanation guys.

[@Sleeperdude]

Good information

[@916chevyboy]

Doesnt impedance mean resistance...?

[@Onalky87]

Is the injector driver 554-143 needed when using a low impedance billet atomizer 550 or similar large injector for methanol

I will keep asking you guys this on the phone and on the web until I get an ACTUAL real answer... WHY WONT YOU SELL INDIVIDUAL REPLACEMENT INJECTORS FOR THE HOLLEY SNIPER. you sell them for the other injection systems, but not for the sniper? Nobody wants to take their sniper off the engine, ship it to you guys, wait 4-6 weeks, and loose time using the car while you take 5 minutes to plot in a new injector. WE ALL want to buy a replacement injector, leave the sniper on the engine, plop in the new replacement injector and hit the road. please, make sniper injectors readily available for purchase. It is NOT a safety issue as you guys claim.. for heaven's sakes, you sell fuel lines, fuel fittings, carbs, fuel pumps, and on and on... so how is an injector any more dangerous. PLEASE, smarten up.

I’m not certain on the sniper, but i know that most all throttle body injection systems need to have all injectors flow matched to maintain proper delivery. so maybe that’s why they don’t just sell one individually

The answer isn’t made in China copies of Rochester/Delphi injectors.
