🔥 Teleflex 18-5179 Ignition Coil: A Reliable Solution for Efficient Engine Performance Review

Don't buy these, it's not Sierra. Complete garbage! Of the four ordered, only two worked, and those two gave off a spark for a week. STAY AWAY!

Be careful when installing, tighten the grounded side and "squeeze" the other side, otherwise the coil will break one of the ears due to its bent shape. Also, the Sierra coil is not marked, for example, the one in the photo is universal.

Fits perfectly, looks better than the original coil that was on the outboard before the replacement. I rented the boat today and with the new coils the boat ran better without hesitation. After the ride I removed the spark plugs, they were clean, to be honest they looked like new. It's been a long time since the candles looked so good after a trip. In short, this product works and I would buy again at any time.

no i repeat do NOT buy this offer! The high quality German coil pictured is not what you get. I opened the package and was immediately disappointed, the reel looked very cheap and generic with a small paper tag that said 'Made in Taiwan'. I installed it anyway - no change, it turned out I had a burned head gasket, replaced it - no change. After a lot of time and frustration I thought what the heck, I put the old coils back in and BOOM, ran like a top! The last thing you need when…

Without even 10 hours of work on this coil set (three of them for 70hp Johnson) the coil on the second cylinder failed. When I was at the lake And I had to limp to the pier. Luckily I had a spare coil on a 30 year old 70hp 3 cylinder Johnson that was on my trailer fishing boat. There are no identifying marks or brand logos anywhere on the Sierra reels. After working as a professional automotive technician for 40 years, I've found that companies that are so aware of their parts they don't even…

CHECK IT IN POCKET, DON'T EVEN OPEN IT, I didn't and 3 out of 4 of these coils were immediately bad the bag. The motor ran poorly with them and I removed 2 new 18-5784 power supplies that were installed with them. I bought four to have one as a spare. it turned out that the one I had on the shelf as a spare failed the resistance test (showing an open instead of 275 +/- 50 ohms) on the secondary circuit, albeit STILL IN sealed twin bags! everyone has the same problem. I didn't think new parts…
