4-PACK Ignition Coil compatible with Yamaha Yzf-r6 YZF R6 Yzfr6 (2003-2007) Warranty Included

I ordered these coils and they are as advertised. My bike seems to run alot better. I would recommend 👌

Got them for my bike because it had a idle surge so I did a full tune up and.. man best choice of my life for a great price

I’m providing a 5 star review because there service is excellent!I had a coil foul out within 12 months of purchasing and they followed through on the warranty and got me a new set.Wonderful! Now I can get back on my bike!The coils themselves work, get the job done... One coil didn’t fit properly, kept slipping off from compression build up. Not sure what that’s due to...and the one that fouled. Sooo we are 2 for 4 in 12 months....The coils I had in there previously ran in the bike from the manufacturer...it’s a 2004, so roughly 12 years 35k Miles.... this one lasted <12 months... we will see.

These coils worked perfectly in my 2004 R6. A year and a half later experienced a little misfire issue and coilspec sent four replacements free of charge. Great customer service. All in one day and that was a Sunday. Lifetime customer

They worked fine for a bit until eventually one of them disconnected from my wire harness causing my stator not to charge my battery leaving me Stranded at school once, after I just changed the new one for one of my old ones I originally replaced since only one of the old ones was giving me issues and now she’s running perfect. Overall, decent.

Minor adjustments on the rubber incerts we had to cut like 1/8 of an inch off of them and then they fit - after the bike ran great 2007 yamaha r6

They're hard to get to on my bike but once I switched them out the difference was incredible and the stock ones are bad on all 2003 yzfr6's so switch them and have a more powerful motorcycle

I bought this set for my 2007 Yamaha YZF-R6 to fix a low rpm misfire and stumbling idle. They fixed the problem and now my bike no longer sounds like a V twin.
