Review on Spectra Premium C 666 Ignition Coil by Dhoal Shankar

Just as good as Denso OEMs on my 2003 Toyota 4Runner SR5 V6 4x4. Had to replace everything for about 225k because they were just wasted and looked pretty rough. They have already driven about 50,000 kilometers on my car and no problems. I just bought a replacement for a B/C, when I first installed it there I overtightened one of the coils and the bolt broke the hole the bolt goes through (hope that makes sense). I haven't had any performance issues or any sign of this being a problem, but since I'm changing spark plugs again I figured I could go ahead and just replace that ignition coil. They look exactly like the Denso that originally came with the car. I'll try to take the time to give an update on how the ignition coils look after I've removed them to change the spark plugs. I'm sure everything will be fine. Unlike many products that offer "Prime", this one actually arrived within 2 days which was nice, unlike others which actually took 3-4 days despite the "free 2 day shipping". take a while and although I ordered for a week in the morning so no apologies for it not having arrived after 2 days (but that is a note and a problem with Revain not this seller).
