    "Was looking for the Denso spark plugs that came with the car. And ordered them, then it turns out this particular company I don't want to mention sent me an email and said there out and back ordered I requested a refund. While looking online, I came across Pulstars and was impressed. I did notice a little more pep when I hit the gas and the car wasn't laboring. I'm looking forward to put them in my other vehicle."

    "I immediately felt the torque response. The plugs definitely do the job they are advertised to do. I' m a satisfied customer. And I highly recommend them to everyone."

    "I was very excited to recieve my car parts from CARiD, but when I opened my spark plug box, there were only 4 when I paid for 6. After calling Pulstar multiple times explaining the situation, they said they would send two more no problem. I still haven't received my 2 missing spark plugs. Have been in touch and they keep saying they will send it. Not CARiD's fault. "

    "I use this controller on my Honda S2000 with a Turbo and it works great. The only thing is that the stock ECU couldn't see the injectors and had to do a work around to keep engine light off - but it's not a big deal. I am very satisfied with the unit."
