The harness fit perfectly, works great, and included a generous supply of new clamps for single, double and quadruple wires. I was able to install it with fresh new clamps making it look that much nicer.

Very high quality - better than the competition. Go with Kelly - while they only sell through distributors, their customer service cant be beat!

Great fit, great quality. Very pleased.

I firstly purchased a no-name generic harness for my IO-360 C1E6 however, the leads were really just too short for my install and the ends were not marked. I reluctantly purchased this Kelly set (out of frustration), but now that the harnesses are installed, Im really wishing I would have started with the Kelly set. Quality looks to be very good, the ends are marked for correct install / hook-up, and theres plenty of lead length to work with. Apparently, the C1E6 has a different connection pattern than other 4 cylinder Lycomings. I havent had opportunity to start the engine yet, but I have high confidence in the Kelly harness, and Tempest plugs.

Harness received as expected, and worked well.

Install went good. Works fine. From what I have seen of it prior to installation, it looks as good as those costing quite a bit more. I’m sure it will last a long time

as advertised

always in stock. good value for what else is available.

Absolutely as advertised. As each lead was numbered, no chance to mess up and the cap fit perfectly into my Slick mags. Included in the kit was everything we needed. Aircraft starts and runs much better.

What a awesome setup Very nice Huge improvement Thanks

Called your sales number and wasnt sure which harness I needed. I connected with your salesperson, Tangie. I found her to be extremely Knowledgeable and very helpful as well. I think the company should be made aware of her professionalism.

A better quality harness than the original Champion Slick harness. I also received excellent help from Kelley Aerospace on determining their part number for the harness kit as it was not listed in their application chart for my Lycoming model.

Perfect part. Shipped fast and complete. Got here as expected and saved a AOG from a day of lost revenue. It would be nice to have a special number for AOG situations for even faster service

Great quality, variaty of colors, fit great, leads are appropriate lengths, not too long or too short, and each lead is labeled permanently for position. Started up after installation per markings and ran great.

Got the right part on the 2nd try. Your product support people helped out. The incorrect part I received at first had the correct part number but was not right. I sent it back ($27.54 UPS) and received the correct part.. Since none of this was my fault, I think ACS should have paid for the return. Other than that, Im thankful the issue was resolved.

Product is as it should be. The problem is with aircraft spruce. In stock item, that was needed quickly wasn’t shipped for a week after purchase! Part was in stock in all locations, but was sent from the furthest possible warehouse. Doesn’t make any sense. You guys dropped the ball on this one, and isn’t the first time. Plane was down for to many days for nothing.

Easy to install all labeled great

Made for a specific engine, this harness fits perfectly and works well. Each wire is labeled for the plug it should be connected to and which magneto it should be installed on. It is foolproof. Your mechanic will have a quick installation and the product works fine. Make sure that you have the correct part number for your engine before ordering.

Workmanship excellent and fit as expected. Very happy with steel connectors on plug ends.

Nice workmanship. Clearly marked with which plug each lead goes to. Plenty of installation clamps and tie wraps included with wire set. Despite the picture shown, this set does include harnesses for both mags.

Packed and application Aok

the best price out there. only one out of a dozen had a repairable defect ie part missing.

Seems like a good quality harness. Engine ran great after install. Came with all new clamps too. However, expect to bundle a lot of wire. The leads are almost twice as long as they need to be for my O-320.

Excellent, fit good and fixed the issues. Customer service was great.

Great set, my only complaint is the number 1 bottom wire could be an inch or two longer. That one is tight with my routing configuration, which is a normal configuration.

Easy to install. Be sure to only order 1 since the box contains both left and right harnesses (even though the ad shows a single harness and states “harness”)

It Run Tested Excellent! Price Good. We Found For a 0300D Cont on a Cessna 172 The #1 and 2 Leads Were Almost To Short # 3 and 4 Were Same Length As # 5 and 6 And Were Long. Remaining Was Excellent!

Good Quality from Kelly as usual, but the APPLICATION Chart is NOT Correct....for the TCM IO-550N the only listed part number is NOT CORRECT for the Normally Aspirated IO-550N as installed in a Cirrus SR22. The magneto mounting plate is the wrong size. Apparently this is a well know issue with the Magneto Repair Shops across the country and has been this way on the application charts for many years...
