Mishimoto MMHOSE-GTO-05BK Silicone Radiator Hose Kit Compatible With Pontiac GTO 2005-2006 Black

Great fit and look amazing

Very durable and perfect in length. Had to google many methods to try and slip them on because they are extremily difficult. The method that worked for me was Dawn dish soap (lots of it).

Looks great, installation is a bear as these are a very tight fit over the connections. I ended up removing the thermostat housing so I could brace it against the floor to press the hose on with body weight.

I also have black silicone Mishimoto hoses on my 2006 GTO. The upper hose developed a pinhole leak due to contact with the hose support. The hoses look the part: orange silicone inside, abrasion-proof wrappings on the outside. But I'm super skeptical about replacing them with the same part. I've had cheep parts store hoses bulge, scraped, torn, and abused that lasted longer. I'm saying 10/10 for looks. But 4/10 for durability.UPDATE (5/29/15): After extensive searching, I determined that the Mishimoto hoses are the highest quality hoses available for my application, and I gave them the benefit of the doubt on the small pinhole leak--so I bought the set again. After inspecting the new hoses I have upgraded them to four stars. The new hoses still SEEM to be made of the highest quality wrapped silicone. They are an exact fit. That being said, I will suspend a five star rating based on the failure of the first set.PHOTO: old hoses on the bottom/new hoses on the top

This hose was a great bargain as I saved $$ buying a returned item. They're awesome hoses and brand new so I wondered why they had been returned, but my old ones were shot. Way too deteriorated to reuse and I wasn't about to put those back on my brand new 2-core G-Force Aluminum radiator, besides they were only priced a little bit higher than the standard rubber hose replacements. Once I received the new silicon hoses I instantly knew why they had been returned and it wasn't for any poor quality or mechanical issues but THEY WEREN'T RED the box was labeled RED, the picture of hoses on the box had awesome looking RED hoses but not these, they're black. HMMPH! I really needed to get this car back on the road, so I went ahead and installed them. Now these are perfectly fine just plainly colored BLACK hi-performance silicon radiator hoses and wow I am quite happy with the deal I got. If an accidental switcheroo at the factory allowed me to get a high tech high performance upgrade, one that I would otherwise not get for such little extra coin - so be it - I'm fine with my new black radiator hoses for my red GTO. **installation note ** If lower hose seems impossible to force on the t-stat housing water spout, don't give up just TURN IT OVER, the hose has a different diameter on each end, not by much but enough to make it not fit.
