Product Details

The Mishimoto MMHOSE-GM-15U is a high-performance silicone upper radiator hose engineered specifically for 1967-1969 Pontiac Firebird models equipped with 326ci, 350ci, or 400ci engines. This direct-fit replacement hose provides a significant upgrade over original rubber hoses, offering superior heat and pressure resistance for demanding driving conditions.

Key Features:

  • Five-layer silicone construction with heat-resistant embedded fibers for maximum durability
  • Improved heat tolerance to withstand higher coolant temperatures without degradation
  • Enhanced pressure tolerance to prevent hose failure under extreme conditions
  • Direct-fit design ensures proper routing and connection points for easy installation
  • Includes high-quality worm-gear clamps for secure, leak-free connections
  • Available in black for a clean, factory appearance or subtle engine bay styling

Mishimoto silicone radiator hoses are designed to outlast and outperform stock rubber hoses, making them an excellent choice for restorations, performance builds, or anyone seeking a reliable cooling system upgrade for their classic Firebird.

Awesome Prices! were over $40.00 cheaper on my part I ordered from them than anyone else online. I will be back for more parts that's for sure!

cool

Site is nice, wish it had more filtering options, for instance, front brakes only, or rear rotors, etc.

Ordered parts for my civic. Great site, lowest prices (trust me I looked) and great service. Will definitely buy again from them.

Your website is great, but I only made this transaction because you cancelled my last one. I tried to order the Deezee brand box and your inventory was off. Hopefully I'll get this one, I really need my toolbox! Update- got the new box, it's just as ad

Very fast response to order. Only place I could find the product I wanted.

Good, lower price.

LEARNING AND LOOKING FOR BETTER SERVICE

So far so good!

Love the company. Just wished the site had more info on parts.

The items shipped and arrived really fast. This was a great transaction even though shipping was a little high.
