AS3 Performance silicone radiator hoses are crafted from top - quality silicone reinforced with polyester. This makes them sturdier, more durable, and less prone to punctures or damage compared to standard rubber hoses. Many of our sponsored teams and riders use these hose kits in various race conditions. The hoses have a gloss finish with AS3 Performance branding. They fit 2003 - 2007 Kawasaki KFX 400. Features include high - quality silicone with polyester reinforcement, 3 - ply construction with a 4.5mm wall thickness, pressure testing up to 5 times the working pressure. They're used by our sponsored mx and enduro riders at national and world levels, designed for off - road and track use only, not approved for road or public highway use, and come with a 12 - month warranty from the purchase date. The hoses you see in the picture are exactly what you'll get.

Using these AS3 Performance silicone radiator hoses is easy. First, make sure your 2003 - 2007 Kawasaki KFX 400 engine is cool. Then, carefully remove the old radiator hoses and replace them with these new ones. Remember, these hoses are only for off - road and track use, so don't use them on public roads. When it comes to maintenance, check the hoses regularly for any signs of wear or damage. Since they're made of high - quality silicone, they're pretty durable, but it's still a good idea to keep an eye on them. If you notice any issues within 12 months of purchase, you can use the warranty to get them replaced. Just enjoy a reliable and long - lasting radiator hose solution for your off - road adventures.
