Tired of the factory turbo boots on your 6.4 Powerstroke cracking and blowing off? This Mishimoto silicone boot kit is the direct-fit upgrade you need. It's made with their special DuraCore material that's way more resistant to heat, oil, and fuel compared to regular silicone or the stock rubber. That means no more leaks, no more blowouts under boost. The kit includes everything: all the necessary boots and high-quality constant-tension T-bolt clamps to ensure a perfect, secure seal every time. It replaces the weak factory pipe (part #8C3Z-6N651-A). Installation is straightforward, and it's backed by Mishimoto's lifetime warranty. Stop fixing boost leaks and start driving with reliability.
