Reviews for Mishimoto MMCFK-JK-12BK Coolant Filter Kit for 12-18 Jeep Wrangler JK 3.6L

This is a must for older model JKs, especially if any concerns for casting sand in the engine (look it up). I've changed out my filter a few times now, and seems like I still see some sediment every time. That will inevitably gum up the JK heater core, then you are looking at a $2k dealer repair or cutting up your passenger dash. Install is simple with their video. I would say the tubing was very long, probably cut off around 12inches. I have mine under the Airaid CAI which is a massive box, and no issues. I really wish I would have bought this when I got the Jeep, or else FCA should have this as a stock item.

MY 2012 JK was used for the prototype for this kit and I was shocked by how much stuff was filtered out. At the time, my jeep had 65K miles or so, the radiator had already been swapped under warranty (extended) and the coolant system had been flushed. Mishimoto installed a kit and cut open the filter after 1,000 miles and then again after another 1000 miles. each time the filter had pulled a substantial amount of casting sand/debris out of the cooling system. This is a must have for the jeeps with the 3.6 that have been known to have casting sand left in the block from the factory.

Have a problem with my heat in my 2014 JKU blowing Luke warm at best. Was told this kit will
Help filter out the particles in the heating system. Install was easy.

Just installed my kit today, it was very easy. just keep in mind this is a bypass style system. There is no need to worry about the filter being filled with casting debris (sand) and starving the coolant flow. I am excited to put some miles on the jeep and cut open the filter to see all the grit and grime.
