Overview

Note: Photo is for reference only. Individual items may differ.
Product does not come with mag back plate. Only fits screw on mag back plate. Only fits 5/8" spark plugs. Production ignition harnesses at remarkably low prices. Late type 5MM wire constructed of 16 strands of tightly braided copper wire impregnated with scuff resistant white silicone. All strands must fracture before a complete open circuit type failure occurs thus extending lead life. Lead flexibility is retained from -65° to 400°F. Moisture & cleaning solvent penetration is eliminated by the impregnated silicone coating. This extremely flexible wire lends itself to sharp bends thereby eliminating the need for old style harness elbows. No soldered joints in the grounding circuit. Custom made for most 4 & 6 cylinder engines using Bendix or Eisemann magnetos and 4 cylinder engines using Slick magnetos. Cable outlet plates are not furnished for Bendix & Eisemann mags as these are already installed on the magnetos in service. They must be purchased separately for new magneto installations. Harnesses for Slick magnetos are furnished with the backplates installed. Standard harnesses for the Bendix S4/S6 mags are fitted with a male nut which screws into the threaded outlet plate on the back of the mag. Harnesses for old style Bendix SF4 and SF6 magnetos are fitted with female nuts. ACS Products ignition harnesses can be used on experimental aircraft or on certified aircraft with field approval (FAA Form 337). If FAA/PMA harness is mandatory or if for use with 3/4" spark plugs, use Slick Bendix, Aero-Lite or Champion harnesses. Made in USA |

Reviews
The ignition harness looks great and came with installation instructions. The price was decent as well
Good Value
Nice harness, well made.
Good harness . some type of elbows would be helpful on most cylinders.
They look pretty good and should work but I only needed half of them since I have half an EI system.
Perfect on the lower cylinders. An inch longer on the top leads what have been 5 stars
O320 harness was a great length on bottom but too could use a inch or two more to be perfect fit. It fit okay though.
Leads are a little short for an O-320. Had to buy a second set & replace a couple with longer leads due to the bend radius on a couple cylinders looking like they were kinked over which wouldnt last.
Ordered as advertised for my 029D. 4 lines fit normally. 2 lines were a bit snug. 2 longest lines did not fit(2-3 in short) and will have to be replaced. Very frustrating and costly. Not recommended for 0290D.

The ACS Products harnesses do not have 90* elbows, and are not FAA approved. Intended for use on experimental aircraft only.
These are priced and sold per engine. You will get a left and right harness.
ACS harnesses are made to be used with 5/8" barrel spark plugs, and the magneto cap is not included for Bendix mags, they hare threaded leads. The harnesses for Slick mags have the magneto plate swaged to the harness leads.
The units do not come with the documents for a 337. The aircraft owner will need to discuss the approval process with the A&P and possibly work with the manufucaturer for specific details.
There are crimping instructions included.
These would need to be installed into your current harness plates.
No this will only work with s4/s6 mags. You would need a Kelly aerospace harness for a dual mag.
This will work with S4 mags and REM/UREM plugs on C-85 and O-200's.
Yes, please look for the "SF" after the engine to specify scintilla mags.
