I was looking into Koni Yellows for a couple of my cars. My Honda mechanic told me they ALWAYS leak and have to be shipped back to Koni to have them fixed under warranty. He told me to go with a different brand because of this. I guess they have a good warranty but if you have to take them off, send them in and wait for them to come back, it could be a huge PITA. Just passing what he said on, I don't have any experience with them myself.
