Instead of paying 80 dollars for each one and I needed 6 ...wow..thats a lot of penny for someone who lives pay check to paycheck. I was honestly scared to buy these for what it cost me for one?? Im sure it has to be cheaply made or plastic or a toy. You never k ow what is coming in the mail.. A TOY CAR PART..LOL. These were absolutely amazing and they really work and last. Ive already had in my 2004 chevy trailblazer for almost 2 years and still running great..

Tengo dos meses desde que se las puse, sin ninguna falla , se ven de muy buena calidad. Excelente compra. Saludos desde mty n.l.

Plug & play as it were, everything fit perfect & she's running like a kitten now. Quick delivery & great pricing.

I only had 1 bad coil but opted to replace them all since im at 175k miles. Though other reviews said they got some faulty coils, i did not. My previous misfire, which was very evident when cruising at freeway speed between 60 and 70mph was corrected and my trailblazer is running great again. Its a really easy install. 10mm socket and a common screwdriver is pretty much all you need. Take the coilpack out to disconnect the wiring clip to make the job easier. Push it up with your screwdriver and it will easily release. Trying to do it while the coilpack is still bolted down is much harder since the clipholding the wore connector is facing away from you. A mechanic wouldve charged a lot.
