Koyo Radiator Reviews

905/05/2013350ZThis radiator is working like a charm. Looks great, performs very well, and the installation is quite straightforward. My turbocharged car has always been running a bit hotter and this upgrade really solve my engine temperature problem.
1003/15/2013Civicgood looking high quality easy to install typical koyo product
903/12/2013SupraVery pleased with rad. keeps the engine much cooler. only reason i didnt give it a ten is because thermo switch fitting didn't come with plug in it. necc to locate one before use. $400.00 rad missing $2 plug, and its made for this application. so a rad cap wouldn't hurt either. other than that. its a needed addition to a modded supra and i love it!
911/13/2011tCI had my friends at Vivid Racing install the KOYO along with Mishimoto dual fan cowling, Mishimoto race thermostat, Mishimoto Heavy duty trans/cooler and Agency Power silicon radiator hoses... The difference in engine cooling and power/throttle response is amazing. I was very pleased with my purchases thru HorsePowerFreaks. Your website is a very good resource for information on performance parts for my car. Thank you... Sincerely, Eric
1011/25/2010Accordthe quality of this product is above my expectation and easy to install just making a slight modification
705/25/2010SupraPacking was shrink wrapped so well it was fused to the radiator and it took several hours by hand with my fingernails to remove all the clear plastic. A non metallic scraping tool might have speeded up the process but I didn't have one available. The radiator went right in and was a perfect fit, all stock components bolted right on, no issues there. While putting on the shroud though, the overflow pipe fell off so the factory solder job was inferior. Im afraid to let a radiator shop fix it as they might ruin the nice welds so Im using an epoxy to hold it on. The car runs cooler than the stock rad but still gets too warm with an electric fan with the factory shroud so Im using the stock 2JZGTE water pump with a 95 LS400 and the stock 86.5-92 fan. Im in Kuwait though and its getting over 100 now so Ill go electric in the winter.
1002/28/2008SupraInstalled well, No problems
711/08/2007Supralooks great.I bought this for an 87 supra turbo.the radaitor came with an extra hole for a thermal car didnt come with a thermal switch.koyo doesnt supply a drain plug or a for 400.00.HPF is sending me a 16mm drain plug.
1010/24/2007Accordperfect part cools the engine perfect!! get this rad!
1006/28/2007240SXgreat product!!!!!
1006/06/2007Accordyou cant go wrong with this radiator if you want good looks and preformance look no farther
