Note: 12304-32 1 Mag Cap with 4 Leads per order (see Image 1). 12304-33 and 123404-31 are sold as a set, 2 mag caps with leads. Will fit 5/8" spark plugs only.
Ignition harnesses 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
Really nice set of wires at a price BUT, if your mag is very tight to the fire wall, the shoulders they use to keep the wires straight coming out of the mag cap, adds about 1/2 to the length of the magneto. Only a problem if you were already against the fire wall.
Delivered promptly in good shape
The parts arrived about a week after ordering, and were a perfect fit. There were no machine screws, so I used the old ones. Otherwise there were no problems.
I found this item to be well made and of very nice quality for my RV-4
Fast delivery and perfect fit. No problems at all with installation.
They fit well and perform great. The shielding is encapsulated in a silicon outer coating/sleeve making them stiffer and larger in diameter than the original. This is a very good value compared to OEM product offerings.
fit perfect ,ran much better after install
It installed ok leads are a tight fit. Leads should be numbered.
It looked like a well made part but was the wrong harness. I need the harness for Bendix mags p/n 12301-22. The harness I received was for slick mags 12304-33. I have sent the slick harness back with an explanatory note including the required code number for returning a part, now I await shipment of the correct part.
Dont know yet not starter engine, however hardware is not useful. plug ends not labeled. price is great if all goes well. Thank Jerry
Yes, part # 12304-32 is a single mag cap with 4 leads.
The 12304-33 does have the shielding built in the wire. All ACS Products ignition harnesses are shielded.
Yes. There is a left and right side and they are labeled as such.
Yes, this is sold as a set for left and right mags.
The ACS Products harnesess all have ends to be used on 5/8" barrel aircraft sparkplugs. They do not offer an automotive style sparkplug connectors.
It comes with 8 leads. It is a complete harness.
Per Vendor: The Slick mag caps are all the same size, and this harness is for Slick mags, per the application info on-line and catalog.
This will be viton rubber.
No, this is the only colored it is offered in.
The caps are metal and the includes the harness for left and right mags. We wouldn't have access to previous 337's. Part number 08-13303 is a certified Kelly version and wouldn't require a 337, might be a better option.
