    Well they were very responsive for my questions. After receiving the product i had a question and they responded within a couple hours yes not days which is almost unheard of these days. Shipped as they said it would very fast i was impressed alot of sales these days say it will arrive by a certain day and it doesn't. The packaging was also first class, i was also impressed on that, box wasn't damaged either. They were spot on!

    Absolutely amazing and perfect transaction!  The seller made an exceptional offer on this rather expensive item, and I was thrilled to accept it.  shipping time was amazing as well and being new and using Federal Express. It arrived in perfect shape and exactly as expected. I highly recommend the seller and will be planning to purchase from them again in the near future. They also had follow up communication to be sure that everything was OK and I appreciate that as well. Thanks !

    Sent them an email asking about shipping and to be sure the springs were indeed in stock. They emailed me back right away and confirmed they had them ready to ship. So I ordered them on a Wednesday night and had them by Friday afternoon! Awesome customer service!

  • Mishimoto 99Miata radiator

    It is amazing how small the original radiator is...the Mishimoto is not only MUCH better quality, it has greater volume and cooling abilities. It look a little bit of fabrication to the original fan shroud framimg, but all went well if you just take your time with the installation. Very pleased with this product.

  • Much better cooling than stock - looks great

    It's a nicely made piece that brightens up your engine bay. The increased capacity over stock fixed all my overheating issues. Pretty straight forward to fit but be aware that very early '99s (like mine) have AC lines that interfere with the lower rad mount on the passenger side and need to be bent down by ~0.5 -1 inch before the unit will fit (yes I transferred the rubber grommets and everything!)

  • Mishimoto aluminum radiator

    Bought this product at a great price. The craftsmanship and fitment was great , I live in Southern Arizona where temperatures are high. The Mishimoto radiator keeps my engine running cool even in the worst traffic conditions. A great addition to any cars cooling system.

  • Great radiator

    Bought this to replace the original unit which had developed a leak between the upper tank and the cooling fins. Twice the cooling capacity and all aluminum tank housing compared to the plastic original. Looks great and installed with only a minor modification to the fan housing bracket.

  • Wished it Worked Out

    Might have just been a "one-off" issue, but everything was great except the aluminum drain plug was stripped and cross threaded into place from the manufacturer. It ultimately leaked and caused me to need to park the miata until i can get it warrantied potentially. But otherwise it was great looking and seemed to be promising.
