Z1 G37 Silicone Master Hose Set

The hoses are of superior quality and value. I didn't see any instructions for installing which hose to which orifice. I had my mechanic do the installation and he is quite competent and it took him quite some time to ascertain the correct locations. I still have several that were not able to be installed. That is why I gave it 3 stars. I hope I can get some sort of installation drawing to be able to install the last 4.

Looks really good material is absolutely perfect

Gave my engine a new look also breathing a lot better feels like a new engine great product!

Great product, will last a long time.

Got the hoses when I got my engine swap and haven’t had a problem since. Went with red to dress up the engine bay a little bit. Gives it a cleaner look with the new engine.

The oem hoses get brittle over the years. this kit is a must.

Had a few oem hoses that were deteriorating pretty bad and leaking and these solved that problem and look a lot better too.

The quality is perfect. The fit is perfect. Even though all of the hoses are not really visible, I am happy knowing that they are there. Z1 is definitely my go to for all of my Infiniti needs!

I received the master kit from Z1 in red. Most pieces were obvious but I was able to refer to the pics on z1 to make sure I knew which hose went where. The hardest hoses to replace are the heater core hoses, and the brake booster hose seems like it won’t fit but it does after adjusting the hard line behind the engine bay heat shield. I recommend using the screw style hose clamps as re-using the factory clips was not practical. The kit looks great once fully installed.

Installed on my 08 G37S coupe. I got the blue to match my paint. Hoses are high quality, look nice under the hood, and give it a little pop of color. It would be nice if the hoses were labeled, but it wasn't too hard to figure out where they went. This set includes a full length heater hose to replace the two hoses and plastic bleeder valve on the driver's side, so I also bought the Z1 metal bleeder and moved the bleeder to the hoses on the passenger side and got rid of the plastic bleeder and coupler. Installing the heater hoses at the rear of the engine was a huge pain involving blood, sweat, and tears. Watch some YouTube videos before hand. You will definitely need long 16" needle nose pliers (straight and 90° bent). My old rubber hoses were fused to the metal pipes which caused the most pain. You just have to twist until they break free, and then the hoses will come off. Other hoses weren't too bad to install besides having to drain coolant and power steering fluids.

100% recommended. Good Quality.

Fit easy just don’t forget to get new clamps

Nice 👍 I loved good material

a must have and will save you in the long run

Superior build quality to OEM rubber hose, highly recommended to freshen up your engine bay and prevent leaks.

great product, looks great and better than stock.

My original hoses had burst and leaking coolant from at least 3 different areas. These hoses fixed that. These guys weren’t lying when they say “these are the last hoses you will ever need”.

Really good quality. Super happy to have this in Spain. Super fast delivery. Takes time on warehouse but this is not a Z1 deal. I can’t wait for purchase a lot of items from the shop for my g37. Here aren’t much dealers for aftermarket parts and its a luxury have the super high quality parts from Z1 in our country. Thanks for all!

Every single coolant hose you will every need if you buy this kit

I’ll be perfect if inside the packages we received too a label with each hose where is supuse to go

All great quality silicone gives me some piece of mind upgrading from the oem ones that don't age well.

I love is don't have to worry about the oem hoses it looks amazing under the hood installation was ok just sum tight spaces to get into

Great material and amazing color

Great materials and fit good.

I ordered the master silicone hose kit for my g37x. The only thing I wish was included would be 8mm hose for the throttle bodies. Everything else was outstanding quality and fit perfectly.

Shipping was super fast and product is exactly how described in add. Material is top notch and the color (red) is very vibrant.

AWESOME!! 10/10 , improves the flow of fuel lines too.

Great product, very easy to replace from OEM hose thank you!

This master set is a great product. Rad hoses were super easy to install. Power steering hose install was easy also. PVC hoses were easy. Coolant overflow fill and overflow hoses were easy to install. Now the heater hoses, they are exceptionally difficult. The IM has to be off the car to be able to reach the rear engine to firewall hoses. I also recommend taking the driver side motor mount nut loose on the bottom and jacking up the engine on that side. Also recommend a OTC Drake Off Road15 Cable Type Flexible Hose Clamp Pliers ($30, Amazon) to remove factory clamps in hard to reach places.
