To determine which Peak & Hold you need

  1. Grab a multi-meter and select Ohms 200
  2. Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
  3. Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
  4. Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)

High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.

*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

Good and Cheap
Works great on my 1997 Honda Accord EX 2.2L. Great value for the money. Installed it myself. Only a 30 day warranty though.

Works well. Installation pe

Body of starter is longer than the original. Still fits but changing the starter on a BMW space is at a premium. Also had to grind down edge of battery cable to fit on solenoid. Aside from that starter was fine. Working well
