are there any good hose kits out there for an S4 NA? I want to replace all the rubber with some good silicone hoses. I don't want any colors or anything, just a black silicone hose.

 

There are some sold by rx7store.net and mazdatrix.com

They aren't kits but you should be able to determine how much you need in FT.

hosetechniques.com has really good prices and quality hose. Thats where I always got all of mine from. They also ship really fast.

 

I have both the mazdatrix kit and hosetech, one on my N/A and the other on my 10thAE and I must say that the hosetech kit seemed to hold up to the heat of the turbo alot better than the mazdatrix kit did! Even though the guy at mazdatrix told me they buy from the same manufacture as hosetech the quality of hose wasn't the same! I can say this because I originaly put the mazdatrix kit on the AE, I went through a summer and one winter and my pressure sensor hose became very brittle and during a routine check cracked, I decided to try hosetech kit and its been 2 years and I can still freely move the hose. Hosetech was also abit cheaper. I also didn't buy the hole kit, I bought the starter kit and it worked just fine. Oh and the hose diameter and thickness is the same from both mazdatrix and hosetechnics, maybe I just got ahold of some old hose stock but I would go with hosetech. They also have every color you could think of!

sweet. thanks guys

 

You don't need to use silicone. The stock rubber hoses lasted for well over a decade on your car so its longevity isn't really an issue. If you just want black lines, save yourself a bunch of money and buy new rubber ones from an autoparts store.
