Disaster rarely strikes at opportune moments when you have all the tools and resources to overcome it. Radiators crack at the track just after the last parts store closes. You got the last fitting they had but went one rotation too far and righty-tighty became righty-loosey. Rent, the electric bill, and that cracked block came due on the same day. It's Sunday night, 10-degrees outside, there's a puddle of coolant under your car, and you just need to get to work tomorrow. Sometimes, being an enthusiast means learning how to pivot and do what's necessary to get home. For those times, Mishimoto is here with our tested and proven Liquid Chill Stop Leak by K-Seal.----This stop leak has been independently lab tested and proven to seal holes up 0.6mm in diameter and cracks 0.25mm wide by 12mm long, without clogging your radiator or engine coolant passages. The key to this ability is its special blend of microfibers and copper particles that are small enough to flow freely through the cooling system. When pushed through a hole or crack, those particles and microfibers begin to build a wall that seals the leak. Heat and exposure to atmosphere or combustion gasses then cure the sealant for a permanent fix.----The best part of our stop leak is its simplicity. Simply shake the bottle, add it to the cooling system, and run the engine. Liquid Chill Stop Leak is compatible with all coolant types and doesn't require any special preparation. Liquid Chill Stop Leak provides a permanent seal without clogging cooling passages, so it can be left in the system or flushed with your next coolant change. So, if you're in a pinch, or are just tired of hunting for a solution to your coolant leak, look no further than Mishimoto's Liquid Chill Stop Leak.Shipping Notes

High quality cabin filter
Size: 8.3" x 9.3" x 1.3"
I change out the cabin filters in my cars at every oil change. It help when running the A/C all summer. This is high quality cabin filter that does its job. Seeing what the dealer wants for literally 1 minute worth of work is silly.

It works as expected
Size: 8.3" x 9.3" x 1.3"
Great. It does block air flow by a bit, but it is ok, if you don't need strong air blowing your face at maximum setting all the time.

Great cabin filter for 2019 Acura RDX
Size: 8.3" x 9.3" x 1.3"
When I have my car serviced at the Acura dealership, they routinely recommend that the cabin filter be replaced. As we all know, a dealership is going to charge an arm and a leg for a basic service. Therefore, I have been replacing the cabin air filter myself for the past few years. I like BOSCH products and when I found this filter on Amazon, I knew that was the one to purchase for my 2019 Acura RDX. The filter fits perfectly in its location in the glove box. It literally takes less than five minutes to swap out the old filter for the new. I will continue to use this product while I have the RDX.

Perfect fit, easy installation.
Size: 8.3" x 9.3" x 1.3"
This part fits perfectly. Directional flow is printed on the part however you need to confirm which way air flows in the actual air box. The easiest test is to run the a/c with the filter out, wet a finger, and stick in in the air box to see which side the air blows cold. Then just install this part in the air flow direction as printed on the part. I have not noticed a difference in air quality yet, however I imagine being a HEPA filter, this will do wonders keeping pollen out of the car. Installed this in a 2011 Honda CR-Z. Easy installation. Part looks high quality which is fitting for Bosch.

Great filter, but doesn't fit 2013 Honda Fit without modification
Size: 8.3" x 9.3" x 1.3"
Right off the bat: I don't have any airflow problems with this filter. It works great, the air is noticeably cleaner, and airflow has not been meaningfully reduced. However, it doesn't fit my air filter holder very well.
The ' air filter holder' (a plastic tray that slides horizontally into the air flow system) has two plastic fringes on either side of the tray, which each have two small notches in them, a few inches apart from one another. This appears to act as a sort of 'key' by which you can gauge you are putting the filter in with the correct alignment. On an OEM filter, the slots line up with two strips of material that stretch across the length of the filter, which themselves rest within the slots. However, the slots don't line up with the strips on this filter. I had to cut the fringes so that the slots in them are wider, so the strips would fit in them. Without doing this, the filter wouldn't press down into the tray.
Having done that, and the filter now rests flush in the tray, there are still marginal gaps around the perimeter of the filter. It's a millimeter or two too small for the tray, so there is some airflow around the filter. This could be rectified by wrapping insulation tape or something around the edge of the filter, or could be ignored if you're not super picky. I haven't added any wrapping to get an airtight seal, and even with that gap I still noticed that the air is way better.
So ultimately, it didn't fit exactly, but it fits 90% of the way and, with some finagling, is a superior filter by any other measure.
